Pliskova, Kvitova cruise; Osaka pushed by Doi

Pliskova overcame a slow start to top Anhelina Kalinina 6-4, 6-0. The Czech was broken in the first game of the match, but soon recovered to take a 4-1 lead only to see the Ukrainian rally back to draw level at 4-4 before the top seed streaked to the finish, winning the final eight games to reach round two.

"I think this match, especially the first set, was in a couple periods", she said via video conference. "I think I started not really great with the first game, but after, I was able to somehow, like step in the court, was playing quite aggressive, so I was doing a lot of points.

"I felt better than in my match previous, last week, what I have played on Court 17. I think the center court is better place to play no matter [if] it's still without people, but I just felt somehow a little better. I had a lot of practices on this court, so I just felt quite used to it.

"And also, just to play without people, I think that even I just had one match without people [last week], but I thought it quite help me just to know how it feels."

Osaka closed play on Arthur Ashe Stadium with a 6-2, 5-7, 6-2 win over countrywoman Misaki Doi. The 2018 broke twice in a dominant first set only to see Doi gained an early break to go ahead 2-0 only to see her lead evaporate, but she broke at the end of the set down 40-15 to force a third.

The two-time major broke in the third game of the deciding set and never looked back, breaking a second time in the seventh game after the world number 81 missed a backhand and held to 15 to close out a tougher than expected opening-round victory.

"It was very difficult", she said in her on-court interview after the match. "I kind of expected it because of the first round nerves, and she's also a very tough opponent. I knew there was a chance it would get really long. I just have to see what happens tomorrow and how I feel."
