Twenty-year-old Atlanta native Ben Shelton beat Aslan Karatsev 6-4, 3-6, 6-2, 6-0 Friday at the U.S. Open in New York to reach his second Grand Slam tournament fourth round.

Shelton, the son of former Georgia Tech player and coach Bryan Shelton, reached the quarterfinals at this year’s Australian Open.

Shelton will next face 14th-seeded Tommy Paul, who defeated No. 21 Alejandro Davidovich Fokina 6-1, 6-0, 3-6, 6-3. Paul served up the last of his 15 aces to close out the match.

No. 6 Coco Gauff, a former Atlanta resident, beat 32nd-seeded Elise Mertens 3-6, 6-3, 6-0. Gauff will face Caroline Wozniacki in the fourth round. Wozniacki earned a 4-6, 6-3, 6-1 victory over Jennifer Brady.

Tenth-seeded American Frances Tiafoe moved into the fourth-round with a 4-6, 6-2, 6-3, 7-6 (6) victory over No. 22 Adrian Mannarino, the fourth straight year he has gone at least that far at the U.S. Open, beating Rafael Nadal on his way to the semifinals last year.
