Sunday's sports briefs

Nikolay Davydenko won the first big tournament of his career Sunday, running down just about every ball and using a consistent serve to beat U.S. Open champion Juan Martin del Potro 6-3, 6-4 and win the ATP World Tour Finals.

"Maybe I had good concentration. I was surprised," Davydenko said.

Del Potro had three chances to break Davydenko, but the Russian saved them all, completing a sweep of all three of this year's Grand Slam champions at the season-ending tournament. He beat Roger Federer (Wimbledon, French Open) in the semifinals and Rafael Nadal (Australian Open) in the round-robin phase.

"He's very fast," Del Potro said. "He plays like PlayStation."
