Nick Kyrgios insisted he had no need to apologise to Rafael Nadal despite blasting the ball at him at one point in their Wimbledon match.

"Why would I apologise? I won the point," said Kyrgios after his four-set second-round defeat. "I was going for him. I wanted to hit him.

"The dude has got how many Slams, how much money in the bank account? I think he can take a ball to the chest."

Nadal managed to get his racquet in the way but said the shot was "dangerous".

"It is not dangerous for me, it is dangerous for a line referee, dangerous for a crowd," the Spaniard said.

"When you hit the ball like this, you don't know where the ball goes.

"I know he's a big talented player, but I am a professional player too. I know when you hit this kind of ball, the ball can go anywhere."

It was only one flashpoint in a stormy 6-3 3-6 7-6 (7-5) 7-6 (7-3) win for two-time champion Nadal.

The build-up

The pair met on Centre Court five years ago when a 19-year-old Kyrgios, ranked 144th in the world, pulled off a shock four-set victory over the then world number one.

Before Thursday's encounter their head-to-head record stood at six wins apiece, with Kyrgios winning a testy encounter in Acapulco in February.

In the wake of that win, the Australian had described Nadal as "super salty" in defeat and admitted earlier in the Championships that the pair would not be sharing a drink any time soon.

Underarm, but underhand?

One of the flashpoints in his win in Mexico had been Kyrgios' decision to serve underarm. He produced the same tactic twice on Centre Court, winning the point on each occasion.

He was asked afterwards why he did not attempt it more often with Nadal standing deep behind the baseline to field a serve that delivered 29 aces.

"If I do something outrageous, I get destroyed in the media for it. I thought I'd be professional and hit a normal serve. That's what I was thinking," he said

"No, I'm kidding. I just didn't want to hit another one. Oh, shoot me down for not hitting an underarm serve Centre Court against Rafa.

"What do you want from me, man? I don't know what you want from me."

Clashes with officialdom

During the first half of the match, Kyrgios repeatedly argued with umpire Damien Dumusois, mainly about the time that Nadal was taking between points.

Kyrgios described the official as "a disgrace" during the match and his opinion had not mellowed in the aftermath.

"The umpire today was horrendous. I mean, he was terrible

"The rule is like play to the speed of the server. Why do I have to wait for Rafa to get into his rhythm every time?

"I thought the way he handled the match was just bad."

Analysis

Three-time Wimbledon champion Boris Becker:

"I want Nick Kyrgios to learn from that, he's such a fine tennis player, we want him in tennis, we maybe even need him in tennis once the big three are gone.

"Yes you should get emotional every now and then but don't get emotional for nothing. You're not going to change the tennis world without winning a major.

"Quite often these blockbuster matches that we talk up when we see the draw just don't deliver because one player is too strong or one doesn't turn up. This one I was pleased it didn't end in a bar-room brawl."

DAYTONA BEACH, Fla. – The IMSA-sanctioned Porsche GT3 Cup Challenge Canada by Yokohama series was at Canadian Tire Motorsport Park just two months ago for Victoria Day SpeedFest, and it returns for another equally big weekend with the IMSA WeatherTech SportsCar Championship.

While CTMP hosted the opening rounds of the 2019 GT3 Cup Challenge Canada season, this weekend’s Mobil 1 Sports Car Grand Prix marks the fifth and sixth races in the series’ 12-round championship. The two most recent races were held at the Formula One Canadian Grand Prix in June at Circuit Gilles Villeneuve in Montreal.

All eyes will be on Roman De Angelis, the 18-year-old who is riding a three-race win streak that started when he won Round 2 at CTMP. De Angelis then proceeded to sweep the doubleheader weekend in Montreal in his No. 79 Mark Motors Racing Porsche 911 GT3 Cup car, which will be one of 14 on the grid this weekend.

“I’d just like to start by saying what a performance by the team in Montreal,” said De Angelis. “It was a really important weekend for me, and for it to come off perfect is what I could have hoped for. I cannot wait for the upcoming back-to-back weekends with Mark Motors. I really hope we can keep the momentum pushing at Canadian Tire Motorsport Park.”

De Angelis has built a 15-point lead in the championship standings over Parker Thompson in the No. 3 Porsche for SCB Racing. One point separates the drivers in third and fourth place, with Patrick Dussault in the No. 77 Lauzon Autosport racecar having 112 points and Jeff Kingsley at 111 in the No. 16 Policaro Motorsport Porsche. Kingsley was the winner of round one at CTMP.

Seven drivers in the field are also competing for the Platinum Masters championship for drivers 45 and older. Again, a narrow one-point margin separates the top two contenders in that title hunt. Alan Metni in the No. 99 Kelly-Moss/AM Motorsport Porsche has 120 points and Marco Cirone with 119 in the No. 88 Porsche with Mark Motors.

It’s Cirone, though, that has claimed two of the four Platinum Masters wins so far this season and two overall podiums, making some competitors view him as one to beat.

One of those competitors is Michael Levitas in the No. 37 TPC Racing Porsche. Levitas joined the GT3 Cup Challenge Canada field at Montreal and scored a Platinum Masters victory of his own in round four.

“I’ve raced quite a few times at Canadian Tire Motorsport Park and I’m really excited to come up there and race,” said Levitas. “I just can’t say enough about being able to join the Canadian series and I feel really fortunate to be able to race with everybody. I’m looking forward to some great racing and maybe I’ll have something for that Marco Cirone.”

DAYTONA BEACH, Fla. – Brad Keselowski sent a message to the entire Monster Energy NASCAR Cup Series garage on Thursday at Daytona Int’l Speedway.

The message was simple, he’s not going to lift.

Keselowski delivered the message during the final practice ahead of Saturday’s Coke Zero Sugar 400 at Daytona Int’l Speedway and the unfortunate recipient was William Byron.

Entering turn three, William Byron was in front of Keselowski in the draft and was running half a lane up from the bottom. Keselowski got a run on Byron and rather than back off, he ran into the back of Byron’s Chevrolet and turned him sideways.

Byron, somehow, managed to save his car from crashing and he returned it to the garage. However, his Hendrick Motorsports team decided that enough damage had been done to switch to the backup car for Saturday’s race.

Keselowski said after the incident that he was simply sending a message to Byron and anyone else who might try blocking in the draft.

“I had a big run and it put me in a position where I had to lift. I keep telling these guys I’m not lifting,” Keselowski said. “I hate it for his team and that they’ve got to work on their car and so do ours, but I’m just trying to send a message. I’m not lifting.”

The message that Keselowski sent was nearly the same message he delivered after he crashed out of the 2018 edition of the Coke Zero Sugar 400 at Daytona.

“We’re not wrecking enough people. We need to wreck more people so they’ll stop throwing bad blocks,” Keselowski said in 2018. “That’s what is happening to me on the plate tracks. Everybody that is watching all them drivers out there throw another bad block, I’m just going to drive through you and wreck you.”

Byron said he felt like there was no reason for Keselowski to use his bumper the way he did.

“It’s practice, I get it, but I don’t think it was necessary to turn us there,” Byron said. “It wasn’t like I changed four lanes down the backstretch and blocked him. I was just kind of holding my lane and he just used his run to drive into my left rear.”

Looking at the speed charts Thursday, Kyle Busch led the opening round of Coke Zero Sugar 400 practice with a 200.754 mph lap. The second practice was paced by his Joe Gibbs Racing teammate Martin Truex Jr., who circled the 2.5-mile superspeedway with a fast lap of 205.935 mph in the draft.

Qualifying for the Coke Zero Sugar 400 is scheduled for Friday at 5:05 p.m.

Australia 218 for 6 (Perry 62, Mooney 43*) beat England 217 (Beaumont 114, Kimmince 5 for 26) by four wickets

Australia took an early grip on this Women's Ashes contest, completing a difficult chase with ominous efficiency to move 2-0 up in the ODI leg and claim another two points. Tammy Beaumont shone for England with a maiden Ashes hundred but England's innings listed badly as Delissa Kimmince claimed 5 for 26 and Australia then marched to victory on the back of Ellyse Perry's half-century and some composed finishing from Beth Mooney and Jess Jonassen.

It could have been worse for England, who saw Katherine Brunt helped from the field after twisting her ankle celebrating the wicket of Meg Lanning - though she was later able to return and bowl. However, they also might have had cause to question a tight stumping call that went Perry's way on 4, despite not seeming to have any boot clearly grounded behind the line. Had the decision gone in favour of wicketkeeper Amy Jones, deputising after Sarah Taylor was sidelined by a "niggle", Australia would have been 22 for 3.

Despite losing both openers inside three overs, Australia showed greater collective purpose on a used pitch that was never easy to score on but did not deteriorate significantly. Perry and Rachael Haynes put on 53 for the fourth wicket to ease concerns after Brunt had bowled captain Lanning with a perfectly executed slower ball, before the seventh-wicket pair of Mooney and Jonassen banished any thought of a nervous finish to match the first ODI with a brisk 60-run stand.

With Brunt limping off, England's confidence in their ability to defend a middling target seemed to ebb. Haynes took on the slow bowlers, lofting the only six of the match off Sophie Ecclestone and using her feet well to hit down the ground; Perry was more orthodox, waiting for anything short or overpitched to pounce on as she brought up her 27th ODI half-century.

Although Haynes fell to a smart caught-and-bowled by Laura Marsh, and Perry nicked a wide long-hop from Shrusbole, England could not quite force the door down. Ashleigh Gardner played around a cutter from Shrubsole to raise hopes again but Jonassen struck her third and sixth balls for four to signal her intent.

England now find themselves 4-0 down in the points-based Ashes, needing to win the series outright. "We've done it before, going to have to turn it around very quickly," Heather Knight, England's captain, said. "It's a massive game down in Canterbury [venue for the third ODI]."

That they were in this contest at all was largely down to Beaumont, who became the first Englishwoman to score a century in an ODI against Australia since Sarah Taylor in 2009 (and the first by anyone not called Taylor since 1993). Although she said afterwards she "never felt in", Beaumont managed to go at almost a run a ball while scoring more than half of England's runs; the only one of her team-mates to come close to matching her fluency was Danni Wyatt, who made 25 off 25 balls.

Although England again lost Jones in the second over to Perry, there was no repeat of the top-order collapse that undermined them in the first game. Knight struggled to find scoring opportunities in her 17 off 47, but she shored up one end as Beaumont found her groove during a partnership worth 65.

After Knight's dismissal, trying to hit Gardner over the top, Beaumont raised a half-century from 44 balls. Having used Perry's pace to get away several early boundaries, she lofted Jonassen down the ground and then took to relying on the paddle sweep against the spinners, scoring a significant proportion of her runs behind square on the leg side as Australia declined to plug the gap.

Nat Sciver became the first of Kimmince's victims, trapped lbw by one that skidded on, and Fran Wilson did not last long but Wyatt showed good purpose in helping put on another useful alliance with Beaumont. They had put England on course for what seemed like a score in the region of 250, but Wyatt was well caught by Alyssa Healy standing up to Megan Schutt and Beaumont fell in the following over, dragging on attempting a reverse-swat through the off side.

Two wickets in eight balls allowed Australia to squeeze in the field, with England unable to find the boundary after the 38th over. Kimmince returned to bowl a miserly line at the death, picking up Brunt and Shrusbole in the same over and then two in two balls to finish the innings with her maiden international five-for, as England lost their last four wickets for six runs and with 2.2 overs left unbowled.

Shaun Marsh is out of the World Cup with a fractured forearm. He was struck by a ball from Pat Cummins while batting in the nets at Old Trafford, two days before Australia's final round-robin match against South Africa.

Peter Handscomb will replace Marsh in Australia's squad. Handscomb is already in England with the Australia A team that is touring the country concurrently and is set to join up with the World Cup squad on Friday.

Marsh wasn't the only batsman to suffer a blow to the arm at Australia's training session. In the same net, Glenn Maxwell was hit on the right forearm by a short ball from Mitchell Starc. Both batsmen aborted their net sessions and went for scans immediately.

Australia coach Justin Langer has confirmed that while Marsh has been ruled out, Maxwell hasn't suffered extensive damage.

"Shaun Marsh has had scans on his right forearm after being struck while practicing in the nets at training today," Langer said. "Unfortunately, the scans have revealed Shaun has suffered a fracture to his forearm which will require surgery.

"This is obviously shattering news for Shaun and the squad. Throughout this tournament, his spirit, professionalism and the way he has competed has been typically outstanding. We are right behind Shaun in his recovery and rehabilitation.

"Glenn Maxwell also underwent scans after he was struck on his right forearm in the nets. The scans have cleared Glenn of any serious damage and we'll continue to monitor him over the coming days. We are hopeful he will be fit to perform for us on Saturday against South Africa.

"We have made the decision to call up Peter Handscomb to replace Shaun in our World Cup Squad of 15. Pete is a like-for-like player, in terms of batting in the middle order, and he performed very well for us during our recent tours in India and the UAE."

Handscomb narrowly missed out on a spot in Australia's original World Cup squad, showing impressive form in the lead-up to the tournament but having to make way for the returns of Steven Smith and David Warner from their ball-tampering bans.

Since the turn of the year, the wicketkeeper-batsman has scored 479 ODI runs at an average of 43.54 and a strike rate of 98.15, with three fifties and a match-winning century in a chase of 359 against India.

Philadelphia Phillies right-handed reliever Juan Nicasio has been placed on the 10-day injured list with a left groin strain.

Manager Gabe Kapler says Nicasio's strain is "pretty mild." Kapler says Nicasio needed the break because the pitcher also has been feeling tightness in his quadriceps.

Nicasio, who was acquired from Seattle in the offseason, has a 5.24 ERA in 34 1/3 innings pitched.

His roster spot will be filled by left-hander Austin Davis, who was called up from Lehigh Valley.
