Frances Tiafoe has advanced to the fourth round at Melbourne Park, his first appearance in the Round of 16 at any Grand Slam.

The 20-year-old American from Riverdale in Prince George’s County beat 34-year-old Andreas Seppi, 6-7 (3), 6-3, 4-6, 6-4, 6-3, on Court 3, where matches began 2 1/2 hours late because of morning rain.

After trailing by a set and 3-0 in the second, Frances Tiafoe, an alum of the Junior Tennis Champions Center in College Park, turned the match around to get to the third round at a major for the second time. 

The No. 39-ranked Tiafoe, an alumnus of the Junior Tennis Champions Center in College Park, beat fifth-seeded Kevin Anderson in four sets in the second round, and followed it up with a biceps-slapping celebration that drew plenty of attention.

He will next play 20th-seeded Grigor Dimitrov, who beat Thomas Fabbiano, 7-6 (5), 6-4, 6-4, earlier Friday.

After his win, Tiafoe paid homage to LeBron James by copying the four-time NBA MVP's “Silencer” — raising his knees and pushing his palm-down hands toward the ground. He also had yanked off his shirt before doing that move.

Marylander Frances Tiafoe is making waves at Wimbledon, and faces Russia’s Karen Khachanov on Saturday.

After his previous victory, a second-round upset of two-time major finalist Kevin Anderson, Tiafoe mimicked another James celebration by flexing his right biceps and slapping it five times with his left hand.

“Be interesting to see if [other players] want to try them. Just trying to bring something to tennis,” said Tiafoe, who turns 21 on Sunday.

He said his post-match choreography is not premeditated. It just sort of happens.

“If I get a chance to do it on a big court, big situation, you've got to bring it up,” he said. “I don't know what celebration I'm going to do. I got a lot of them that I know.”
