Tsitsipas cruises past Anderson; Goffin handles Coric
Fourth seed Tsitsipas broke the big-serving Anderson four times and saved all three break points, which came in the fifth game of the second set, to cruise past the two-time Grand Slam finalist 6-1, 6-3 in just 69 minutes.
"I think the fact that I kept my serve very aggressive and remained aggressive with my groundstrokes helped me a lot and I'm very pleased that I was able to maintain my game throughout the match", he told ESPN following the win.
Goffin claimed a 7-6 (6), 6-4 victory over Borna Coric to improve his head-to-head record against the Croat to 5-0.
"It was a big battle until the end of the first set", he said. "I think winning the first set was the key because after that, I didn't lose my serve. I served well until the end. The surface is very quick so when you are aggressive and you serve well, it makes a big difference."
