MELBOURNE, Australia — Frances Tiafoe rolled up his white shirt's right sleeve, flexed his biceps and slapped the muscle five times. Then he pounded his chest and yelled, “Yeah! Let's go! Let's go! Come on!”
Forgive the young American's exuberance. This was, after all, the biggest victory of his nascent career.
Down a set and 3-0 in the second, the 20-year-old from Riverdale in Prince George’s County came back to stun two-time Grand Slam finalist and No. 5 seed Kevin Anderson, 4-6, 6-4, 6-4, 7-5, on Tuesday in the Australian Open's second round.
“I went to a different place. I dug insanely deep,” the 39th-ranked Tiafoe said during an on-court interview. “It's all about competing. Guys are so good. It's just about how badly you want it. I want it real bad.”
He was joined in the third round by another kid from the U.S. who'd never been that far at Melbourne Park, 21-year-old Taylor Fritz, who saved 12 of the 13 break points he faced while dispatching No. 30 seed Gael Monfils of France, 6-3, 6-7 (8), 7-6 (6), 7-6 (5).
Next for Fritz is a matchup against Roger Federer, the two-time defending champion in Australia and owner of 20 Grand Slam titles.
“I grew up watching a lot of the guys I play today. I can't tell you how many times I watched Monfils' highlight reel on YouTube, just growing up. `Fed,' obviously, my whole life growing up, he was always the best, winning everything,” Fritz said. “So it's really cool being able to step on the court with him again.”
For Tiafoe, it helped that Anderson's best attribute, his intimidating serve, slowed down along the way because of problems with his right arm. Anderson was repeatedly visited by a trainer during changeovers and he lost about 5 mph on his first serves as the match wore on.
Anderson was the runner-up at Wimbledon last year and at the U.S. Open in 2017 and had won all three previous matchups against Tiafoe.
But Tiafoe, an alumnus of the Junior Tennis Champions Center in College Park, ended a six-match losing streak against top-10 opponents and is now into the third round at a major for the second time, equaling his best showing.
“These are the matches where they kind of define you and help you feel more and more comfortable to keep winning matches like that,” Tiafoe said. “So, yeah, I'm definitely going to remember this one.”
As for his postmatch flex, Tiafoe said: “I hope the crowd liked it.”
Defeat Andreas Seppi of Italy next, and Tiafoe would make his debut in the second week of a Grand Slam.
He turns 21 on Monday and said: “If I'm playing on that day and beat somebody, that's the best present I can get.”
Earlier Tuesday night, No. 18 seed Diego Schwartzman of Argentina, defeated Denis Kudla, another JTCC alum, 6-4, 7-5, 3-6, 6-7 (6), 6-4.
Kudla, 26, ranked No. 62 in the world, nearly rallied from a two-sets deficit for the second straight match after beating Melbourne resident Marc Polmans, a former junior doubles Australian Open champion, 5-7, 1-6, 6-2, 6-3, 6-2, on Monday.
Another 20-something from the United States threw a scare into another older, more-accomplished top-10 foe, but Mackenzie McDonald couldn't match Tiafoe's or Fritz’s upsets, losing to No. 6 Marin Cilic, 7-5, 6-7 (9), 6-4, 6-4.
Cilic was the 2014 U.S. Open champion and the runner-up at Melbourne Park to Federer last year. Against McDonald, an NCAA champion in singles and doubles at UCLA who is 23 years old and ranked 81st, Cilic delivered 25 aces, including on each of the last two points.
Federer, seeking a record seventh Australian Open title and third in a row, reached the third round by beating Dan Evans, 7-6 (5), 7-6 (3), 6-3.
“I couldn't pull away early in the match,” said Federer, who actually was two points from dropping the opening set.
The defending women's champion, Caroline Wozniacki, also advanced in straight sets, beating Johanna Larsson, 6-1, 6-3, and could face Maria Sharapova next.
Also scheduled to play later Wednesday were past champions Rafael Nadal and Angelique Kerber.
No. 5 Sloane Stephens opened the day in Rod Laver Arena with a 6-3, 6-1 victory over her junior doubles partner Timea Babos.
Stephens, the 2017 U.S. Open champion, reached the third round of the Australian Open for the first time since 2014.
“I'm kind of conquering all the places where I've been terrible,” Stephens said.
Four seeded women were sent home, including No. 24 Lesia Tsurenko of Ukraine, a 6-0, 6-2 loser against 17-year-old American Amanda Anisimova. No. 9 Kiki Bertens, No. 20 Anett Kontaveit and No. 29 Donna Vekic also exited. Vekic lost, 6-4, 4-6, 6-1, to Kimberly Birrell, a 20-year-old Australian ranked 240th who got into the field as a wild card.
“It is so surreal,” Birrell said. “That was just such a blur. I get to play again. It's crazy.”
