Former Georgia men’s tennis All-American John Isner continued his impressive run at Wimbledon with a 6-4, 7-6 (8), 7-6 (4) win against Greece’s Stefanos Tsitsipas during Monday’s fourth round.

The victory puts Isner into the quarterfinals at Wimbledon for the first time in his career. He is looking to become the first former Georgia men’s tennis player to advance to the finals of a grand slam singles event since Mikael Pernfors made the finals of the French Open in 1986.

Isner will now face Canadian and No. 13 seed Milos Raonic on Wednesday.

A native of Greensboro, N.C., Isner was a four-time All-American at Georgia from 2004-07 and helped lead the Bulldogs to a perfect 32-0 record and a national title as a senior. He holds the school record for career singles (138), doubles (138), and combined (276) wins.
