Roddick reigns supreme at Key Biscayne

KEY BISCAYNE: Andy Roddick used a dominating serve and a smart baseline game to beat Tomas Berdych 7-5, 6-4 and win the Sony Ericsson Open on Sunday.

Roddick coaxed an errant backhand from Berdych on championship point, and responded to the crowd's cheers with a thumbs-up. He improved to 26-4 this year, the best record on the men's tour. He also won the tournament in 2004. This was his fifth Masters 1000 title, his first since 2006.

“The last month has been real good for me,” he said. “I've played well on the big moments. I've been able to have a game plan and execute it, regardless of what kind of shots it takes. So it's all good. It's all encouraging.”

Varying the pace

Roddick, seeded sixth, varied the pace on his groundstrokes to keep Berdych off balance while committing only 16 unforced errors.

He had 13 aces and never faced a break point. Roddick lost only seven points on his serve in the second set and dropped just two service games in the tournament.

Roddick's slice backhand repeatedly forced the 6-foot-5 Berdych to hit the ball at ankle level, robbing his forehand of power.
