Murray loses in opening round at US Open tuneup

Top-seeded Rafael Nadal dropped out Sunday night to prepare for the US Open after winning his fifth title of the year in Toronto.

Murray had his best result since missing 11 months following hip surgery when he reached the quarterfinals in Washington two weeks ago. But he had a hard time adjusting to the Cincinnati courts.

"The start of the match was not good," he said. "It was a pretty bad first set. After that, it was a little better."
