DOHA, Qatar — Andy Roddick lost 6-4, 6-2 today in the final of the Qatar Open to defending champion Andy Murray.

Murray showed no signs of a back injury that bothered him during Friday's semifinal win over Roger Federer. He converted all three of his break points against Roddick in the tuneup ahead of the Australian Open.

"I served well and I didn't allow Andy to break me," Murray said. "I also knew Andy can get confident on his serve so I tried to stay ahead of him in the match."

Murray broke Roddick to go up 3-2 in the opening set, and used two more breaks in the second to take a 4-1 lead. Roddick's only break point came with Murray serving for the match, but the Scotsman saved it with an ace and clinched the title with a backhand winner down the line.

"He's in top form right now," Roddick said. "I think he is capable of winning the big ones."

In an exhibition in Abu Dhabi last week, Murray defeated Federer and top-ranked Rafael Nadal. Murray looks to win his first major at the Australian Open after losing to Federer in the U.S. Open final last year. At Wimbledon, Murray lost in the quarterfinals to Nadal.

"I am not close to my best tennis," Murray said. "I need to do what I did at Wimbledon and the U.S Open last year. But if I play my best tennis, then I can beat the top players."

Roddick wasn't dissatisfied with his week in Qatar.

"I made him beat me," Roddick said. "I didn't give it away so easily. It was a successful week for me."
