Felix Balshaw vs Aleksandar Kovacevic — R64 — Winston-Salem Open

Serve settled this one, and only one of them held up: Kovacevic won 91% of his first-serve points and was never broken across 11 service games, while Balshaw took zero of 11 return games. Both breaks landed in the opener, in game 3 for 2-1 and again in game 10 for the set, and the qualifier saved a match point before the tiebreak ended it in 1 hour 17 minutes. The 96th-ranked winner, who came in with no prior meetings on record against Balshaw, banks just his second win in seven matches and a second round at the Winston-Salem Open.
