KANSAS CITY, Mo. (AP)Patrick Mahomes threw two touchdown passes, rookie Jaylen Watson returned an interception 99 yards for the go-ahead fourth-quarter score, and the Kansas City Chiefs held on to beat the Los Angeles Chargers 27-24.

Mahomes finished with 235 yards passing, and Jerick McKinnon and Justin Watson hauled in the TD passes for the Chiefs (2-0), who fell behind 10-0 in the first quarter and spent most of the game playing catch-up.

Jaylen Watson finally put the Chiefs ahead after the Chargers (1-1), answering Matt Ammendola’s tying field goal, marched to the Kansas City 3. Justin Herbert was eyeing tight end Gerald Everett when Watson, a seventh-round pick making his first start, stepped in front of the pass with 10:29 to go and ran nearly untouched the other way to the end zone.

Things became worse for the Chargers (1-1) two series later when Herbert was drilled by Mike Danna delivering a throw. He left the field clutching his side, returned one play later, then threw an incompletion that forced the Chargers to punt.

Clyde Edwards-Helaire promptly split the defense on a 52-yard run to set up a field goal for Kansas City.

PITTSBURGH (AP) – The Pittsburgh Steelers placed star outside linebacker T.J. Watt on injured reserve, meaning he will miss a minimum of four games while recovering from a left pectoral injury.

The Steelers already had ruled Watt out for Sunday’s visit by New England. The NFL’s reigning defensive player of the year sustained the injury in the fourth quarter of last week’s overtime victory against Cincinnati.

Pittsburgh coach Mike Tomlin said earlier in the week that Watt’s injury wasn’t as bad as initially feared. Watt received multiple opinions during the week and does not need surgery, which opened the door for him to return at some point this season.

TENNIS

Roger Federer is retiring from professional tennis at age 41 after a series of knee operations, closing a career in which he won 20 Grand Slam titles, finished five seasons ranked No. 1 and helped create a golden era of men’s tennis with rivals Rafael Nadal and Novak Djokovic.

Federer posted what he called a ”bittersweet decision” via both a written statement and an audio clip, less than two weeks after 23-time major champion Serena Williams played what is expected to be the last match of her career.

Federer has not competed anywhere since Wimbledon in July 2021, and so, in that sense, his news is not all that surprising. But he had appeared at an event marking the 100-year anniversary of Centre Court at the All England Club this July and said he hoped to return to play there ”one more time.” He also had said he would return to tournament action in his home country at the Swiss Indoors in October.

In Thursday’s announcement, Federer said his farewell event will be the Laver Cup in London next week. That is a team event run by his management company.

BASEBALL

NEW YORK (AP) – On a Roberto Clemente Day particularly meaningful to both of them, Francisco Lindor and Carlos Carrasco propelled the New York Mets past the Pittsburgh Pirates 7-1 to extend their slim lead in the NL East.

Lindor launched his 24th home run to set a Mets season record for shortstops, and Carrasco (15-6) struck out 11 in six splendid innings as New York moved a game ahead of idle Atlanta. Slumping designated hitter Daniel Vogelbach drove in three runs against his former team, and pinch-hitter Mark Vientos had an RBI single for his first major league hit.

Breaking out early at the plate in the opener of a four-game series, the Mets halted a five-game home losing streak and rebounded from a three-game sweep by the Chicago Cubs at Citi Field.

PHOENIX (AP) – Drey Jameson pitched seven shutout innings in his major league debut and the Arizona Diamondbacks hit three home runs in a 4-0 victory over the San Diego Padres.

Jameson, called up Thursday from Triple-A Reno, gave up two hits – both by Brandon Drury – and walked one. He struck out five – including Juan Soto twice – and got 10 ground outs. He threw 90 pitches, 62 for strikes.

Kevin Ginkel, Joe Mantiply and Reyes Moronta finished the three-hitter. Ketel Marte, Emmanuel Rivera and Carson Kelly hit solo homers.

The Padres’ lead over the idle Milwaukee Brewers for the final National League wild-card spot was reduced to 1 1/2 games.

GOLF

NAPA, Calif. (AP) – Rickie Fowler shot a 5-under 67 and was among nine players who finished their rounds four shots behind leader Justin Lower at the Fortinet Championship.

Lower, beginning his second PGA Tour season and 15th as a professional, concluded his career-low, 9-under 63 in the early evening at Silverado Resort and Spa. He held a two-shot cushion over defending champion Max Homa and a three-shot lead over Byeong Hun An, S.H. Kim and J.J. Spaun at the fog-delayed PGA Tour season opener.

Lower, whose career-best finish in 28 PGA Tour starts dating to 2013 was a tie for eighth in July at the Barbasol Championship, had a bogey-free round.

Homa, finishing just before play was called because of darkness, birdied two of the last three holes for his 65.

GUIDONIA MONTECELIO, Italy (AP) – Rory McIlroy’s first competitive round on next year’s Ryder Cup course was a success.

The four-time major champion holed out an approach shot for an eagle en route to a 4-under 67 for an early share of the clubhouse lead in the opening round of the Italian Open on Thursday at the Marco Simone club outside Rome.

With later starters still on the course, McIlroy was tied for the lead with Gavin Green of Malaysia and Adri Arnaus of Spain.

Defending champion Nicolai Hojgaard, who played in a group with McIlroy and two-time Italian Open champion Francesco Molinari, finished one stroke behind the leaders.

McIlroy went 5 under over his final seven holes.

PORTLAND, Ore. (AP) – Ayako Uehara found momentum from par saves on her opening two holes and turned that into a 7-under 65 for a one-shot lead in the AmazingCre Portland Classic.

Hannah Green had a 66 despite a bogey on her final hole at Columbia Edgewater Country Club, with Nelly Korda in the group another shot behind.

Also at 67 were former Women’s British Open champion Hinako Shibuno and Caroline Inglis. Brooke Henderson played in the afternoon and joined the group at 68.

AUTO RACING

BRISTOL, Tenn. (AP) – Ty Majeski scored his first career Truck Series win and locked a spot in the championship finale.

Majeski, in his 40th career start in the trucks, became the first driver to earn a spot in the championship-deciding final four. He had a clean jump on Zane Smith on a restart to with 12 laps remaining to cruise to the victory in a Toyota for ThorSport Racing.

The 28-year-old from Wisconsin ran only four Truck Series races last season as he desperately tried to continue his NASCAR career. It led to a full season ride with ThorSport for this year and now a shot at the series championship.

Bristol marked the opening race of the round of eight in the Truck Series playoffs.

Smith finished second after starting at the back of the field. Parker Kligerman was third and, followed by Grant Enfinger, Matt Crafton and Derek Kraus.
