European champions Portugal got their Euro 2020 qualifying campaign back on track with goals from William Carvalho, Goncalo Guedes, Cristiano Ronaldo and Bernardo Silva helping them to a pulsating 4-2 Group B victory in Serbia on Saturday.

The victory lifted the Portuguese to second place in the group on five points from three games, eight behind runaway leaders Ukraine who have 13 from five matches after their 3-0 win in Lithuania earlier on Saturday.

Third-placed Luxembourg and Serbia in fourth both have four points from as many games while Lithuania are bottom with one point from four matches.

Portugal dominated the opening half and Carvalho fired them ahead in the 42nd minute when he poked the ball into an empty net from three metres after Serbia keeper Marko Dmitrovic spilled a Bruno Fernandes cross from the right.

Ronaldo, looking subdued in the opening half and given a hostile reception at Red Star stadium as Serbian fans jeered him every time he touched the ball, twice came close early in the second half.

He fired inches wide from the edge of the penalty area after cutting in from the left and then curled a free kick narrowly off target before Guedes doubled Portugal's lead with a fine individual effort.

The forward capped a flowing move as he sidestepped a defender and rifled in an unstoppable shot past Dmitrovic into the far corner from 12 metres to silence the raucous home crowd.

Centre back Nikola Milenkovic pulled one back for Serbia in the 68th minute, heading a Dusan Tadic corner past keeper Rui Patricio, who was two minutes later forced to tip a fierce Adem Ljajic shot from 20 metres over the bar.

Taunted by chants of "Messi" from Serbia's die-hard fans, Ronaldo demonstrated his class in the 80th minute when he took a Bernardo Silva pass in his stride and coolly dinked the ball over the advancing Dmitrovic.

Serbia refused to roll over as Aleksandar Mitrovic drove a shot from inside the penalty area into the roof of the net after a defensive blunder in the 85th minute but Silva sealed the contest with a clinical finish barely 60 seconds later.

Trevor Bayliss has called on England's batsmen to "put their hand up and be the hero" on the final day of the Manchester Test.

England go into the fifth day requiring a miracle - another miracle - to sustain their hopes of winning back the Ashes. Set an improbable 383 to win in the final innings - their more realistic target is to bat out the final 98 overs on the last day - they lost two wickets within the first four balls of their reply.

While they scraped through to stumps without further loss, the fact that Joe Root and Rory Burns were the men to go will do nothing to increase optimism in England's chances of survival. Root, who was bowled first ball by a perfect delivery from Pat Cummins, has become the first England captain to register three ducks in a series. If Australia win the game, they will take retain the Ashes whatever happens in the final Test at The Oval.

But Bayliss, the England coach, insisted his team could bat out the final day to claim the draw that would sustain their hopes.

"It'll take a couple of our guys to make good hundreds but as we saw in the last Test, anything is possible," Bayliss sad. "It's a big challenge, but we've got two guys out there who are very good players. We've certainly got some players in the sheds who can make hundreds.

"I think we can do it. We've had a chat in the changing room and we're certainly not thinking it's all over. There's no use playing at this level if you don't believe you are good enough to bat for 98 overs and save the game."

While Bayliss could, realistically, hardly say anything else, England's slim hopes have some substance while Ben Stokes remains. He has already pulled off two near miracles this summer - the World Cup final and the Leeds Test - and is England's leading run-scorer in the series. England's supporters will hope he can snare a hat-trick of miracles on the final day.

The form of the other remaining batsmen provides less reason for optimism, however. Jason Roy is averaging 12.42 this series, Joe Denly 23.00, Jos Buttler 13.71 and Jonny Bairstow 25.50. But Bayliss hopes Stokes' success can inspire them with greater belief.

"Stokes' record probably gives the rest of the guys belief," Bayliss said. "If one guy can do it someone else can do it as well. We've already spoken about who is going to put their hand up and be the hero. We know it is going to be hard work, but we're going out there with the aim to do that."

While Bayliss leaves his role as coach straight after The Oval Test, he does have advice for English cricket: ensure home advantage by preparing pitches that suit their side. England were underwhelmed when they arrived in Manchester to find a slow track with very little grass covering. As a result, there was relatively little help for England seamers - who are, with the exception of Jofra Archer - slower than the Australian trio - and they could find no answer to the excellence of Steve Smith. He also had words of mitigation for England's seamers, who struggled in trying conditions on the first day.

"I'd have liked to have seen a bit more green grass on all of the [Test] wickets this year," Bayliss said. "We certainly had that in the Ashes here four years ago - except for the one where Australia won at Lord's. And we won the series.

"What's got to happen in England is that we either play on Test wickets that have some green grass on, like in county cricket, or we play county cricket on flatter wickets with not a lot of grass on so we actually learn how to bat and bowl on flatter wickets.

"Why did England's bowlers not manage the same intensity in the first innings? It was probably the 300mph wind and the minus 10 degree temperature. They were probably the toughest conditions I've ever seen cricket played in. That will take a fair bit out of you, those conditions. The wind was very, very difficult."

It may well go down as the moment Australia truly believed they were set to win the Ashes on English soil for the first time in 18 years. At the very least, Pat Cummins' top-of-off-stump pearler to defeat England's captain Joe Root first ball has set down a definitive blueprint for what the Australians will be attempting on day five at Old Trafford, according to no less an authority on batting than their talismanic run maker Steven Smith.

There was a period on day four when England looked capable of elbowing their way back into the contest, as Stuart Broad and Jofra Archer delivered two of the most compelling spells of a series dominated by the bowlers on both sides. However Smith emerged as Australia's' bulwark yet again, cuffing 82 with help from Matthew Wade and Tim Paine to grant the visitors a handsome lead and the chance to bowl in murky light during the final half an hour.

Cummins responded by drawing an error from Rory Burns in the first over, and followed up with a ball that could not have been bettered to flick Root's off stump. He had copped a similar delivery from Ryan Harris at Durham in 2013, but this one will be remembered not only for the quality of the ball but the importance of the moment. Smith said that it made crystal clear what the Australians needed to do on the final day.

"I think it will be difficult, particularly while the ball is hard. I found when I first went out to the middle, when you bowl a good length, there was enough up and down and sideways movement. My first 20 or 30 balls, I felt pretty vulnerable when they were bowling that good length," Smith said. "Patty hit it beautifully tonight, I think that ball to Root is a blueprint of what we need to do tomorrow, first thing in the morning, and the quicks to keep hitting that top-of-the-stump length and let the pitch do its thing.

"Mixed in with a good bouncer to play with their feet, and maybe get a bit of up and down as well. It's the length we've been trying to hit on Root, particularly early in the innings. It's worked a few times. He's got out first ball a couple of times and early on a few time with a very similar ball. That's the sort of length we tried to hit. Fortunately Patty did it first ball. I have no idea if it moved, kept low or what but I think it's the length that's the most important thing. That was a good length."

Bowlers on both sides have been able to dictate terms with seam more so than swing, and Smith believed this was deliberate: a scrambled seam delivery that can move either way off the pitch being far harder to adjust for than something that moves through the air, though as Mitchell Starc demonstrated to Johnny Bairstow, it can make for a devastating variation if conditions are right. At the same time, David Warner's struggles have been unprecedented in his career, leaving him asking Smith, among others, for answers.

"I think it's off the pitch, that's the key to try and hit that," Smith said. "I don't know what it does when they scramble it, but I guess it just hits the ball in a different spot then can move sideways, there is no doubt in my mind that the seaming ball is the hardest thing to play in the game. You don't have time to react so you have to play the line and if it goes in, you are a chance of hitting the stumps and getting lbw, and if it goes away you are a chance of nicking it.

"A couple of our guys have exploited that pretty well on this wicket and if they do that again and hit the top of the stumps, that same length as the Root ball, hopefully we can see a lot of bowled, lbws and caught behind the wickets. It's been tough on the new ball for both sides. The ball's probably done its most when it's new. When it gets a little bit softer it doesn't do quite as much, it gets a little bit easier. They've bowled pretty well with the new ball. They're both particularly good bowlers to left-handed batters, both Broad and Archer. It's not been easy for Davey and Marcus but they're trying their hardest.

"We've talked, a few different things here and there. Just trying to form a plan to get through Broad. He's admitted himself that Broad's had the wood on him throughout this series and he's been talking to myself and Justin and Hicky, I think, about ways he can play. He's tried a couple different ways and they haven't quite worked. but Davey's a quality player and he hasn't had a great deal of luck this series either, hopefully he can turn it around and get a big one for us at The Oval."

As for his own incredibly prolific series with so much chaos around him, Smith said he had wanted to be involved when the games were at their most difficult, using his singular skills to turn numerous scenarios back around to Australia's' favour. "I think when it is tough you want your experienced players to step up," he said. "I've played quite a lot of cricket now. I like to get into those situations and try and be the one to take the team through.

"I was able to form a really good partnership with Matty Wade, who I thought played really well today as well. That partnership was really handy for us at that stage. England were really up and about with us four down but a good half an hour of batting and things got a bit easier for us and we were able to form a nice partnership, and hopefully one that will set us up for this game.

"I'm not in the game for personal accolades, I'm here to do my job and score as many runs for the team as I can and fortunately this series I've been able to score quite a few and help the team as much as I can. Hopefully I can do that again next game."

Dustin Poirier succumbed to the same fate as Conor McGregor. And no one yet has figured out how to deal with Khabib Nurmagomedov's wrestling. Let alone beat him.

Nurmagomedov defeated Poirier by submission via rear-naked choke at 2:06 of the third round Saturday in the main event of UFC 242 in Abu Dhabi. With the victory, Nurmagomedov unifies the UFC lightweight title. Poirier came in as the interim champion.

The bout was significant for Nurmagomedov, because of the location. Nurmagomedov is a devout Muslim from Dagestan, a republic of Russia, and it was his first UFC fight in a Muslim-majority country. There were loud chants of "Khabib" throughout the main event and many fans wearing Nurmagomedov's signature papakha sheepskin hat.

Nurmagomedov is ranked No. 2 in ESPN's pound-for-pound MMA rankings behind only light heavyweight champion Jon Jones. Poirier came in at No. 9, tied with welterweight champion Kamaru Usman.

Heading into the third round Saturday, Nurmagomedov dominated the entire way with his wrestling and grappling. He was in control for a total of 8:54. Nurmagomedov put Poirier on his back in the first round and nearly got a hold of choke at that point. Poirier survived, but he spent nearly the entire round on the ground with Nurmagomedov all over him. Twice, Poirier went for reversals, but Nurmagomedov ended up with even more dominant positions.

Poirier showed heart in the second. He landed a big right hand and followed with another, putting Nurmagomedov on his heels. Poirier chased the champion in an attempt to rope him into a brawl. It didn't quite work and the flurry seemed to tire Poirier. Once again, Nurmagomedov took him down and put him in the wrestling grinder. Ground and pound opened up a cut near Poirier's left eye.

In the third round, Nurmagomedov shot for a takedown against the cage and Poirier grabbed onto a tight guillotine. He held it for more than 30 seconds, changed positions and it seemed to be close. But Nurmagomedov somehow slipped out. The bout was over soon after. Nurmagomedov got onto Poirier's back, wrapped his arms around his neck, fell back and Poirier had no choice but to tap.

Inside the cage, Nurmagomedov landed seven takedowns and outstruck Poirier, 22-12, in significant strikes. Nurmagomedov has completed 59 takedowns in his UFC career, compared to just two from his opponents. On the ground, Nurmagomedov has outlanded opponents 379-11.

The two respectfully exchanged shirts afterward. Nurmagomedov said he would auction Poirier's shirt off and send the money back to him for his charity. Nurmagomedov said previously that Tony Ferguson, who is on a 12-fight winning streak, should be next, but Saturday he said he needed some time to rest and contemplate.

Nurmagomedov (28-0) remains undefeated and has hardly been challenged in the UFC. "The Eagle" has won 12 in a row in the UFC and he and Anderson Silva are the only ones to start their UFC careers with that winning streak. Silva went 16-0 to begin his UFC run, a record mark.

Nurmagomedov, 30, had not fought since beating McGregor at UFC 229 in October 2018 via neck crank submission in the fourth round. Nurmagomedov was suspended nine months by the Nevada State Athletic Commission (NSAC) for his role in the post-fight brawl at UFC 229, which led to the institution of the interim title.

Poirier (25-6, 1 NC) was unbeaten in six straight fights coming in. The Louisiana native defeated Max Holloway to win the UFC interim lightweight title at UFC 236 in April. Poirier, 30, owns victories over the likes of Holloway, Eddie Alvarez, Justin Gaethje and Anthony Pettis in eight years with the UFC.

Antonio Brown has agreed to a deal with the New England Patriots, his agent, Drew Rosenhaus, told ESPN's Adam Schefter on Saturday.

New England is giving Brown a one-year deal worth up to $15 million, Rosenhaus said. It includes a $9 million signing bonus, $10 million guaranteed and $5 million in incentives.

The agreement comes hours after the receiver was released by the Raiders, ending a tumultuous stint with Oakland after it acquired him via trade during the offseason.

Brown was eligible to sign with any team at 4:01 p.m. ET Saturday. Because of that, he is not eligible to play until Week 2 at the earliest, meaning Brown will miss New England's opener Sunday night against his former team, the Steelers. The Patriots and Raiders do not play this regular season.

The Patriots will have to make a corresponding move once they officially sign Brown, but for now, their receiving corps includes Super Bowl LIII Most Valuable Player Julian Edelman, Brown, Josh Gordon, Phillip Dorsett, and undrafted rookies Jakobi Meyers and Gunner Olszewski. First-round draft choice N'Keal Harry has opened the season on injured reserve.

The agreement comes after Brown asked to be released by the Raiders in an Instagram post earlier Saturday. Oakland had fined him $215,073.53 for conduct detrimental to the team, sources told Schefter, a move that voided the $29.125 million worth of guaranteed money in his deal.

In addition, the Raiders sent Brown a letter stating that he no longer would be entitled to termination pay, sources told Schefter. As a result, Brown would have been playing on a week-to-week basis with both his guaranteed money voided and lack of termination pay.

Oakland, in turn, cut Brown loose Saturday afternoon, and Rosenhaus said he'd immediately try to find a new home for the seven-time Pro Bowler.

"Antonio is looking forward to a new beginning," Rosenhaus said.

The acquisition of Brown moved the Patriots past the Kansas City Chiefs and into the role of Super Bowl favorites at multiple Las Vegas sportsbooks. The Patriots went from 6-1 to 4-1 to win the Super Bowl at the SuperBook at Westgate Las Vegas. The Chiefs are 6-1.

NEW YORK -- The Mets have activated infielder Jed Lowrie from the 60-day injured list for the first time this season.

Lowrie signed a $20 million, two-year deal with New York in January but has yet to appear in a game for the Mets. He felt pain in his left knee during spring training and opened the year on the injured list, then dealt with injuries to his left hamstring and right calf.

The 35-year-old played 12 minor league rehab games and batted .275 (11 for 40) with two home runs. He was activated before a game Saturday night against the Phillies.

Lowrie hit .267 with 23 homers and .801 OPS in 157 games with Oakland last season. He was formerly a client of Mets general manager Brodie Van Wagenen.

Chicago Cubs shortstop Javy Baez has a hairline fracture in his left thumb, an MRI on Saturday revealed.

Baez will see a hand specialist on Monday, at which point a timeline for his return will be determined.

The shortstop missed his fifth straight game Saturday at the Milwaukee Brewers due to the injury. He hurt the thumb sliding headfirst into second base during last Sunday's game against the Brewers at Wrigley Field.

Baez is hitting .281 with 29 home runs and 85 RBIs for a Cubs team that entered Saturday holding the second spot in the NL wild card race, 2 games behind the Nationals and 3½ games ahead of the Diamondbacks. The Cubs are 2½ games behind the first-place Cardinals in the NL Central.
