Victor Estrella insists that at 34, he's not that old. He also laughs off the thought that his tennis career took off at a time when most of his peers are finishing up. After all, the first player from the Dominican Republic to reach the Top 100 of the ATP rankings hasn't played that much. I see that the guys from my generation, from the '80s, most of them have retired,'' Estrella told The Associated Press.

A year after a most painful absence, Maria Sharapova returned to her winning ways at Arthur Ashe Stadium.

John McEnroe and Martina Navratilova, singles champions from three decades ago, slammed tennis balls into the stands before Monday night's matches to ceremonially light the Empire State Building in U.S. - By James Martinez - www.twitter.com/jfmartinez --- THINKING OF UKRAINE: For Ukraine's Sergiy Stakhovsky, just keeping his mind on tennis these days is a challenge. Open match to Andreas Seppi of Italy 6-3, 6-1, 6-4 on Monday, acknowledged the current political unrest in Eastern Ukraine is a distraction. ''Two weeks ago I was there and not very far from what is happening,'' Stakhovsky said, adding that he preferred not to ''disclose'' exactly where he was.

Kyrgios, whose ranking soared more than 70 spots after he upset Rafael Nadal to reach the Wimbledon quarterfinals, said he was frustrated by stretches of poor play against Youzhny when he slammed a ball out of the court to earn his first code violation in the second set.

Venus Williams started with a soft forehand, shifted to a gentle backhand and even tried to blow away a most pesky opponent. ''The bee was a challenge,'' the two-time Queen Bee of Flushing Meadows said after beating Kimiko Date-Krumm 2-6, 6-3, 6-3 in the first round. Williams is 34, Date-Krumm is 43 and their combined 77 years was believed to be the oldest for opponents in a women's Grand Slam pairing, the WTA said. It's just a number.'' Earlier in the match, a bee interrupted Date-Krumm's serve.

Two 23-year-olds, Milos Raonic and Grigor Dimitrov, broke through to their first major semifinals at Wimbledon.

It was then-28-year-old Stan Wawrinka who snapped the streak of 16 straight Grand Slam titles by Djokovic, Roger Federer, Rafael Nadal and Andy Murray when he won the Australian Open in January.

The question made Roger Federer smile. ''It's perfect that we're talking semis and finals already,'' Federer said. He had lost in the second round at Wimbledon and arrived at the U.S. ''I just kind of felt like it was always going to be for me hard beating top-5, top-10 players,'' Federer added.
