Ben Shelton, Taylor Fritz represent U.S. with Wimbledon wins on ...

The Floridian said he thrives in the high-intensity moments of tiebreakers, and it showed. Harris served an ace to make it 7-6 in the final-set tiebreaker before unraveling, and Shelton kept cool to win four consecutive points and take the match after 3 hours 49 minutes.

The left-hander attributes his confidence in high-pressure moments to being able to clear his mind thanks to a plan similar to Novak Djokovic’s approach. The Serbian champion has often said he chooses to focus on one thing when playing tiebreakers: getting every ball back.

“My mind is pretty clear about what I want to do when I get to the tiebreaker: I want to get to the net before the other guy,” Shelton said. “I want to be aggressive on the baseline, but I’m not trying to hit winners. I just want to make the guy come up with a pass — he’s got to hit the perfect return. He’s got to hit the perfect pass up the line or angle or get the lob over my head, and if he does, I’ll walk away. … I’d much rather do that than play a passive game and let the other guy attack me.”

Shelton, the No. 14 seed, will face Canada’s Denis Shapovalov in his first appearance in Wimbledon’s third round.

Fritz, the No. 13 seed, moved on by beating Arthur Rinderknech, 6-3, 6-4, 3-6, 6-4, before telling the Frenchman to “have a nice flight home” during a testy post-match handshake. The pair have history dating from last year’s French Open, when the crowd heckled Fritz after he beat Rinderknech, the last French man in the draw. Fritz said Rinderknech went “out of his way to take a jab” at him before Thursday’s match.

“I’m like: ‘Dude, you know what you said. You know what you said,’” Fritz said. “Don’t disrespect me before the match and then expect me to be all nice after the match. That’s not how it works.”

Fritz faces 24th-seeded Alejandro Tabilo of Chile in the third round.

Elsewhere at the All England Club, top-ranked Iga Swiatek defeated Petra Martic, 6-4, 6-3, to set up a third-round women’s match with Yulia Putintseva. The Polish star is looking to back up her quarterfinal appearance last year, which is as far as she has made it at Wimbledon.

Making the third round, however, is nothing new for her — Thursday’s win made this her 18th consecutive Grand Slam reaching that stage.

“I’m not looking at that kind of broad horizon as you do with statistics. I’m kind of doing everything step by step, and every match matters for me,” Swiatek said. “It’s not like I’m going in the first rounds of Grand Slams knowing that I should win or I should take it for granted. I’m ready to battle even in the first rounds. Yeah, I’m happy that I’m consistent, for sure.”

No. 4 seed Alexander Zverev advanced with a 6-2, 6-1, 6-4 win over unseeded American Marcos Giron. Djokovic had just a minor hiccup while winning his second-round match over wild-card Jacob Fearnley, 6-3, 6-4, 5-7, 7-5. Fearnley, who followed in fellow British player Cameron Norrie’s footsteps and played college tennis at TCU, had the crowd with him on Centre Court. But the second-seeded Djokovic has just a touch more experience than the 22-year-old.

In the third round, the 24-time Grand Slam champion will face Australia’s Alexei Popyrin as he continues to play with a protective sleeve covering his right knee after undergoing surgery to repair a torn medial meniscus last month.

Wang beat Pegula, 6-4, 6-7 (9-7), 6-1, before the American rebounded by notching a women’s doubles victory with Coco Gauff.
