Fritz cruised past Czech Vit Kopriva Thursday, firing 15 aces in a 6-1, 6-4, 7-6 (4) victory. While the No. 9 seed was disappointed not to serve out the clash at the first time of asking, he was pleased overall with his first straight-set win of the season and the state of his knee heading into the weekend.
“I came out playing really, really well. Definitely the kind of like start to a match that I'm looking for. Just felt very calm, in control,” he told press.
“I felt like I was playing aggressive at the right times. When I didn't have the chance, I was being really solid, not giving away any free points. Just a really good level.
“I'd say my knee has been feeling really good the last couple of days.”
Wawrinka, for his part, survived another marathon contest after outlasting qualifier Arthur Gea in four hours and 34 minutes.
