New York finally got some sun, but there was very little shining on male American tennis players at the U.S. Open on Friday.

Fourth-seeded Andy Murray advanced to he semi-finals and on Saturday will face nemesis and defending champion Rafael Nadal, who easily defeated Andy Roddick.

Murray defeated hard-serving American John Isner 7-5 6-4 3-6 7-6, and finished off the match with 7-2 score in the fourth-set tiebreaker in a quarter-final matchup.

Though Isner reached his first Grand Slam quarter-final, he was disappointed with his overall effort. The towering 26-year-old had 17 aces in the match, compared to Murray's 14.

It's been a good run for me, but I'm still disappointed right now, Isner said. I'm not satisfied.

Murray had 47 winners and 20 unforced errors, while Isner had 55 winners and 54 unforced errors.

He put a ton of pressure on me, Murray said. It was a relief to win that fourth-set tiebreaker.

On the other side of the bracket, No. 1 Novak Djokovic faces No. 2 Roger Federer.

First Lady Michelle Obama was in the stands, and seated next to Billie Jean King.
