Rafael Nadal hasn't been in action since losing to Roger Federer at the semifinals of Wimbledon in July, but he told reporters after his victory over Daniel Evans that he was trying to return to his winning ways, per ATPTour.com:
"Always is tough, first match on hard court after such a long time. After Wimbledon, the mind always goes down a little bit because I have been playing a long clay-court season, then grass, so you didn't relax. Then when you finish Wimbledon, it's like your body loses a little bit of that tension, so it needs little bit of time to recover.
"Today, as I said before, the main thing is win. I know with victories that other things should be coming slowly. I have been playing and practising more or less well. Now is the moment to compete. Today I competed enough well to be through. Tomorrow is another challenge."
The next challenge will be facing Guido Pella on Thursday. Don't expect Nadal to take him lightly.
"Today was a good victory that allowed me to be back on court again tomorrow," he said. "Tomorrow [I play] against a player who is playing great. He's having the best year of his career. He's super dangerous, winning great matches. I need to be ready for tomorrow."
While most of the top seeds advanced on the men's side, No. 4 Stefanos Tsitsipas, No. 5 Kei Nishikori and No. 12 John Isner saw their tournaments come to a close.
On the women's side, chalk mostly held, with No. 8 Serena Williams handling her business against Elise Mertens.
Her win included a few brilliant highlights, including some powerful winners:
Meanwhile, No. 2 Naomi Osaka put on one of the day's truly dominant performances before her opponent, Tatjana Maria, retired in the second set. That set the stage for either Osaka or No. 3 Karolina Pliskova to move into the top overall spot on the WTA rankings when the new set is released Monday.
Osaka spoke about her performance after the match, per WTATennis.com:
"I thought I played really well despite the fact that we only played one set. I think that I was able to do what I wanted, which was go for the shots that I had the opportunity to. And, of course, there were, like, a couple unforced errors, but I think that's part of the process. For me, I'm just happy that it was my first match in a while and I was able to get in the groove of things quickly."
Back in the groove, indeed. Osaka is one of the favorites in this tournament, though Williams' strong showing Wednesday was a reminder that she's always lurking as a threat.
