Two-time French Open quarter-finalist Alexander Zverev suffered a shock defeat in the second round of the Stuttgart Open to compatriot and world number 170 Dustin Brown.

German Zverev lost 6-4 6-7 (3-7) 6-3 in the first grass court tournament of the season ahead of Wimbledon.

The world number five, who is yet to win a title on grass, led 5-2 in the second but was taken to a tie-break.

He missed three break points at 3-3 in the decider before Brown broke late.

Brown, 34, who famously knocked out Rafael Nadal in the second round of Wimbledon in 2015, saved 13 of 14 break points as he claimed only his fifth win over a top-10 ranked player.

Elsewhere, Greek top seed Stefanos Tsitsipas lost 6-4 3-6 6-4 to Chilean world number 60 Nicolas Jarry in the first round in 's-Hertogenbosch.

The world number six was playing in his first grass-court match since a dramatic fourth-round French Open exit against Swiss Stan Wawrinka in Paris.

Belgian fifth seed David Goffin comfortably beat Frenchman Pierre-Hugues Herbert 6-3 7-5 in just over an hour and a half in the Netherlands.

Worcester boss Alan Solomons has signed a new deal, committing himself to the Premiership club until the end of the 2021-22 season.

The 68-year-old South African's contract was due to expire at the end of the 2019-20 campaign, but he has been given a two-year extension.

It comes the day after co-owner Jed McCrory quit, leaving Colin Goldring and Jason Whittingham in charge.

"Jason Whittingham and I think Alan has done a great job," said Goldring.

"Alan's contract extension ensures continuity and stability.

"We both support his vision and plan to achieve a sustainable top-flight team with the Three Pears Warriors Academy at its core, supported by top-class talented and experienced players."

Solomons joined Warriors in October 2017, initially as assistant to then boss Gary Gold, before being appointed director of rugby when Gold left two months later.

"I am honoured to be afforded the privilege of being part of Warriors' continuing journey," said former Edinburgh coach Solomons, who was also formerly USA Eagles director of rugby and also coached Northampton Saints and the Barbarians.

Warriors finished 10th in the Premiership last season, winning a campaign-best nine out of their 22 games.

They also reached the European Challenge Cup quarter-finals and the last four of the inaugural Premiership Rugby Cup.

Eddie Jones and assistant John Mitchell are set to continue as England's coaching team until at least summer 2021 after the Rugby Football Union abandoned its previous succession plan.

The union announced in January 2018 that Jones would develop a successor to ensure a smooth transition.

However, new RFU chief Bill Sweeney says this policy has now shifted.

"It is not about him grooming a successor," Sweeney told BBC Sport on Thursday.

Jones and Mitchell could both now stay even if England underperform at this year's Rugby World Cup, with Sweeney adding there is no strict break clause in Jones' deal.

It was previously expected Jones would only stay in his role if England reached the semi-finals in Japan.

"We will sit down and we will evaluate how it has gone and look at the performance and then make a decision which is in the best interests of England Rugby," Sweeney added.

"I think it is a bit unfair to say there is a clause in the contract and it is black and white.

"We feel we have got a really strong coaching set-up now, going through Japan and coming back for the almost-immediate Six Nations and the aftermath of that."

Former All Blacks coach Mitchell has signed a two-year extension to his deal, with Sweeney hailing his impact since joining the set-up last autumn and his strong working relationship with Jones.

However, Sweeney says Mitchell is not currently being earmarked to succeed Jones as head coach.

"He is a proven coach with great credentials, so that was purely the decision, it was nothing to do with succession planning," he said.

"Eddie was instrumental in that approach, and wanted John Mitchell to sign up and be part of his coaching team through to June of 2021, so we approached John from that perspective.

"That came after a conversation with Eddie about his commitment, and he has given that."

Sweeney is the RFU's fourth chief executive in as many years, and inherits a union in the midst of a cost-cutting drive.

However the former British Olympics chief says the financial outlook at Twickenham is not as bleak as he expected.

"It really is not a financial crisis," he said. "Inherently here at the RFU you have got a really strong business model.

"I would say we have gone through a little bit of a blip, a bit of a bump, but we are confident we are going to come out of that pretty strong."

CONCORD, N.C. – Though he set the fastest time in qualifying and finished third in his return to the Bojangles’ Summer Shootout on Tuesday night at Charlotte Motor Speedway, Bubba Wallace was far from satisfied with his results.

Wallace spent the day soaking in as much knowledge as he could during his first Legend car appearance at the 10-race summer series since 2012, a pursuit that was aided by the support of his longtime grassroots owner Chris Rogers, who the Monster Energy NASCAR Cup Series star returned to drive for.

The 25-year-old piloted a No. 76 dressed up in similar colors to one of the cars he drove for Rogers before at the Summer Shootout, progressively gaining on the setup and his skillset as the night went on.

“For me, it was a matter of learning all night,” noted Wallace. “All those little quirks and tricks that you could use to manipulate the car, I’ve kind of forgotten about, so it’s about getting those back and getting to a place where we can go out and win some races, because that’s what we’re here for.

“We weren’t the best tonight; we were really tight in (turns) one and two and just could not get the drive off (the corner) that we needed,” Wallace added. “In turns three and four, I thought we were OK, but it was just too late to make anything happen. It was great to come back out here, though.”

Wallace redrew the eighth starting position after qualifying on the pole, cracking the top five in just two laps and snagging third for good on the fifth revolution, taking advantage of the race’s lone restart after a caution for the stalled car of Ashton Higgins in turn four.

From there, Wallace stayed consistent but couldn’t stay with eventual winner Joey Padgett and runner-up Carson Ferguson, fading to four seconds adrift by the time the twin checkers waved over the field.

“I didn’t know if (Ryan) Mackintosh was going to take the top on that one choose (restart), and he did, but if he hadn’t then I would have and at least tried to make it a race up there,” Wallace said. “We settled in for third, though, and all in all … the car’s in one piece, so that’s a good day.

“Of course, I would have liked to have won, but for showing up with no practice and to sit on the pole (with the fastest time in qualifying) … that’s a good day,” he added. “My redraw skills just need to be a little bit better. This was a good time, but I forgot how long and drawn out these things are. I’m a little older and getting a little tired, but it’s a lot of fun to be back out here, for sure.”

Though he now races wheel-to-wheel with the best in American stock-car racing on a weekly basis, Wallace said there were a few pre-race jitters before he hit the track for Tuesday night’s 25-lap feature.

“I was actually nervous,” Wallace admitted. “I don’t get nervous on Sundays, but I was nervous sitting on the grid. The butterflies were going, for sure, but it ended up working out.”

Much like several of his Cup Series contemporaries who have returned to their short-track heritage in recent years, Wallace was drawn back to the Summer Shootout by a passion for the sport and the “fun factor” of driving a Legend car on the quarter-mile frontstretch oval at CMS.

“This is what racing is all about,” Wallace said. “You’ve seen it a lot lately, with (Kyle) Larson going back to his roots and running sprint cars … and other Cup guys, as well, going to more short tracks. It’s cool to see. The sport has changed so much, and the car counts have decreased from where it was for a long time here at the Summer Shootout, but hopefully my being here helps to spark some interest and maybe get some kids back in Bandoleros and Legend cars again. I had a blast.

“These things are so much fun to drive. Dirt guys will always put sprint cars on top of their ‘fun list’, but I’ll always say Legend cars are number one,” he added.

Ever the competitor, Wallace isn’t resting on his podium result. He’s focused on trophy hunting and intends to add to his 12 career Summer Shootout victories before the end of the season in July.

“We’ll just keep plugging away,” Wallace pointed out. “I know Chris and I aren’t happy with how we ran, so we might be bringing a new car next week. We’ll see.”

CONCORD, N.C. — The CARS Tour is one of the top late model organizations in the Southeast, putting on well-attended shows across the Carolinas and Mid-Atlantic.

Some of the top drivers in the formula — Josh Berry, Deac McCaskill, Tommy Lemons Jr. and others — are regular participants and they draw the big hitters from other groups on a regular basis: drivers such as Phillip Morris, Bubba Pollard and Peyton Sellers.

What the CARS Tour reminds me of, quite honestly, is the American Speed Ass’n when it was in its heyday during the late 1970s.

That’s the feeling I got recently while attending the Old North State Nationals at Orange County (N.C.) Speedway. It didn’t hurt that I attended an ASA race at Orange County that was televised on The Nashville Network, so it was easy to compare the two.

Sure, the ASA back then (2000 or so) was bigger than the CARS Tour. It had TV, sponsorship from ACDelco and others, and featured drivers the likes of Gary St. Amant, Tim Steele and Kevin Cywinski. The competition was fierce, as the .375-mile oval is built for close competition.

There are other comparisons.

In the old ASA, which I grew up around, had its factions. If you were a Bob Senneker fan, you didn’t mix with the Mike Eddy crowd. Dick Trickle was popular, but his fans were loyal to him and no one else.

It’s that way in the CARS Tour, too. Berry fans and Brandon Pierce fans aren’t cooking out together during down times, and there are other rivalries that are rather either/or.

That said, there is a feeling of us against the world when you get right down to it, and that is what makes the series great.

The ferocity of the racing is also similar. Nobody is giving an inch on the track when the money is on the line. For example, in the late stages of the Old North State Nationals, Berry and Lee Pulliam went at it for the $30,000 winner’s check. That late-race battle saw both drivers work to get the other into the marbles at the top of the track and take advantage.

Berry went first and didn’t get Pulliam high enough. Pulliam came back and did get Berry enough into the rubber that it killed his momentum and dropped him back to fourth. Pulliam wound up with the big money.

Many times, I saw the same thing happen in ASA with Trickle, Eddy, Senneker or Mark Martin winning a late-race battle for big stakes and the checkered flag. Like those battles, neither Pulliam nor Berry punted the other, and the race played out between the lines and without an egregious bump-and-run that resulted in one or the other — or both — in the fence.

The CARS Tour competes with the NASCAR Whelen All-American Series for drivers and prestige and while there might be more NWAAS races, there is not a lot of daylight between the two in terms of competition.

The CARS Tour seems to be more of an all-star tour, where the best drivers and teams go. It has that family feel, too, like the one Rex and Becky Robbins engendered in building ASA from local tracks in Indiana into a Midwestern powerhouse that at one point rivaled NASCAR.

Many drivers used ASA as a springboard to the big time. They include Rusty Wallace, Martin, Ted Musgrave, Glenn Allen Jr. and Jimmie Johnson, who ran a season with Howie Lettow for Chevrolet before going on to the NASCAR Xfinity Series and eventually winning seven NASCAR Cup Series titles.

A lot of what ASA did, I see the CARS Tour trying to do, and with a fair amount of success. Ty Gibbs is a frequent competitor, as is Layne Riggs, and development drivers such as Christian Eckes, Anthony Alfredo and Sam Mayer did a season or so in the CARS Tour before stepping up the ladder to the NASCAR K&N Pro Series or ARCA Menards Series.

If the CARS Tour continues to grow — and it will, I think — it could be the second coming of the American Speed Ass’n. The drivers you read about today could be the champions of tomorrow and that would be a wonderful thing.

COSTA MESA, Calif. – MotoAmerica has announced a slightly different qualifying procedure for the EBC Brakes Superbike, Supersport and Liqui Moly Junior Cup classes for this coming weekend’s Championship of Utah at the Utah Motorsports Campus.

Due to the time constrictions of the two-day schedule, Superpole has been eliminated for the UMC round and grid positions for the EBC Brakes Superbike class will be based on each rider’s fastest time from all qualifying practice sessions combined. With Superpole not on the schedule for UMC, Dunlop qualifying tires will not be made available.

For the Supersport and Liqui Moly Junior Cup classes, grid positions for race one will be based on the fastest time recorded by each rider in the qualifying practice, per usual. Grid positions for race two, however, will be based on the riders’ fastest lap from race one. Those classified as DNS will start race two from the back of the grid. Those riders who didn’t start race one will be gridded based on their qualifying time after all the other riders have been gridded.

“After our first two-day event at VIR, we requested feedback from our teams and modified the schedule and qualifying based on that feedback,” said MotoAmerica’s Chuck Aksland. “VIR posed some exciting challenges for the teams, and we think this change will both make the condensed schedule more manageable and a better show for our fans.”

KNOXVILLE, Iowa – Aussies Ian and Kerry Madsen are heading home. Not to Australia. Their other home – Knoxville, Iowa.

When the Madsen brothers moved to America, they landed in the Marion County city of 7,000 people. Their reason?

“It’s kind of the center of the sprint car universe,” said Kerry Madsen, the elder of the two brothers.

The core of that universe is Knoxville Raceway – a half-mile track that’s turned heroes of the Sprint Car world into legends. And the World of Outlaws NOS Energy Drink Sprint Car Series is returning to the iconic track for the first time this season on Friday, June 14, and Saturday, June 15 for the Brownells Big Guns Bash.

Since starting their 410 sprint car careers at the raceway in the early 2000s, both Madsen brothers have found success there. Kerry Madsen won the 2005 track championship and has 21 career Feature wins at the raceway – including a World of Outlaws Feature win. He was leading the points at the raceway before skipping the latest race to compete with the World of Outlaws at Granite City Speedway.

“I’ve always loved Knoxville,” Kerry Madsen said. “Fun place to race. Great crowd. Obviously tuning up for later in the year (for the prestigious Knoxville Nationals). Looking forward to it.”

Ian Madsen won the track championship in 2014 and 2017. He has 12 feature victories at the track, but is still seeking his first World of Outlaws feature win there. A win this weekend would go a long way for Madsen and his KCP Racing team.

Madsen, the 2018 World of Outlaws Kevin Gobrecht Rookie of the Year, claimed his fourth series win at Thunderbowl Raceway in March, but he has been searching for a return to the top-five since the beginning of April. Lately, his results have been a mix of top-10 and top-15 finishes.

“The last few weeks have been pretty rough,” Ian Madsen said. “We’ve had a lot of bad luck. I feel like a lot of it has been out of our control. We just really need to get a good night in and turn our luck around. I think if we just get some luck on our side it’ll take care of itself.”

Along with getting to go home, Madsen said he’s happy to get back to a bigger track after spending the last month mostly on smaller tracks.

“That’s what’s good about the Outlaws, you get to mix it up on all sorts of different tracks,” Madsen said. “Knoxville is the best track in the country, I feel. I look forward to going there.”

Kerry Madsen shares Ian’s sentiment, stating he enjoys the bigger tracks and loves the dedication people in Knoxville have to Sprint Car racing.

Not running full-time with the World of Outlaws, unlike Ian, Kerry Madsen said his one goal every race is to just win.

“Pretty simple,” he said with a grin.

His season this year started off slow, barely cracking the top-10, but lately Kerry and his team have found their rhythm, clicking off top-five finishes more consistently – including two podium finishes in his last five races.

While both he and Ian will be eyeing the win at Knoxville, the brothers don’t let the competition get between them. While many drivers isolate themselves to just their team during a race weekend, every time the Madsen brothers are at the same track its guaranteed you’ll find them together throughout the night.

“We’re always pretty close together,” Ian Madsen said. “It can get pretty lonely out here sometimes. So, it’s good to have him out here to hang out with on the off nights and stuff like that. I enjoy being out here with him. It’s just cool we can both be out here at the same time.”

Before Ian began his racing career at Knoxville, he worked on Kerry’s team.

“We’ve always been fairly close that way,” Kerry Madsen said.

While they’re close, and will share anecdotes about their race car, they’re still competitive. Advice isn’t always shared. For more than one reason, too.

“I try not to give him too much advice,” Kerry Madsen said. “I feel like I try to tell him something and it back fires and he ends up going slower. I just let him figure it out.”

INDIANAPOLIS – The logo for the 104th Indianapolis 500 presented by Gainbridge captures four essential elements – tradition, speed, excitement and innovation – of The Greatest Spectacle in Racing within the framework of the new logo system introduced last year.

Bold, dynamic colors and features form the core of the 2020 logo. At the heart of the design is a continuation of the type lock-up introduced with the unveiling in May 2018 of the logo for the 103rd Running of the race.

“The logo for the 104th Indianapolis 500 presented by Gainbridge acknowledges the traditions and grand legacy of the Indianapolis Motor Speedway while propelling ‘The Greatest Spectacle in Racing’ forward, racing for what’s next,” Indianapolis Motor Speedway President J. Douglas Boles said. “This colorful design reminds everyone of the power and pageantry of the world’s greatest race. The logo is the ‘500;’ it is May.”

The wordmark is athletic, prestigious and confident, and includes a rich red shield that contrasts with gold, the color of the iconic Wing and Wheel logo of the Indianapolis Motor Speedway. This lock-up creates a strong, consistent annual brand appearance for the event.

A new feature of this year’s logo is a checkered flag pattern that races upward and forward behind the shield, symbolizing the goal of every competitor in the race and the rich history of champions at IMS.
