Dubai Championships 2012 Results Day 2: Andy Murray, Roger Federer Advance

In 17 minutes, Roger Federer won the first set of his Dubai Championships opening round match. The second set took a bit longer -- 50 minutes, to be exact. It did go to a tiebreaker, but Federer won that too.

So that's a 6-0, 7-6 (8) victory for the Swiss and a spot in the second round in Dubai.

As for tournament No. 3 seed Andy Murray, it took him three sets to win in Dubai on Tuesday.

Murray defeated Germany's Michael Berrer in two hours and six minutes, 6-3, 4-6, 6-4. The match was Murray's first appearance since his loss to Novak Djokovic at the Australian open in January.

Murray aced the 116th-ranked German just seven times, three of which came in the third set. From SI.com:

"It was quite a frustrating match because I was up a break in the second set, and each time I think gave it straight back," Murray said. "And then the third set again I went up a break and gave the break straight back. So I could have made it a little bit easier for myself if I played a bit better."

Murray will face qualifier Marco Chiudinelli (who also had a three-set victory for his first round match), while Federer takes on Feliciano Lopez in the second round.
