The first game of second-seeded Victoria Azarenka’s match last night at Arthur Ashe Stadium lasted 10 minutes as last year’s finalist finally converted her sixth break point. The rest of the match took just 55 minutes as Azarenka shut out 99th-ranked Dinah Pfizenmaier of Germany 6-0, 6-0, in her first-round match.

Men’s No. 1 Novak Djokovic had just slightly more trouble, cruising past Ricardas Berankis, 6-1, 6-2, 6-2, in his opener to improve to 12-1 in night matches at Ashe.

“I think the night sessions in New York are quite different from any other tournament because of just the vibe that you feel with the people, the crowd gets involved,” said Djokovic, who has reached the past three Open finals. “There’s a lot going on in the changeovers. It’s very exciting, always entertaining. I had experience before and knew how to play. Berankis was playing his first night session. That’s where I was looking for my chance to start pressing from the start, and I was playing on a very high level.”
