German Tommy Haas posted the first big upset in men’s action at the 2008 Pacific Life Open, taking 84 minutes to upset top American Andy Roddick 6-4, 6-4 in their second round match on Sunday in Indian Wells.

Roddick, who had held serve in all 55 games last week in Dubai en route to his second title of the 2008 season, saw his perfect service streak come to an end as he was broken at 4-all in the first set. He dropped serve again in the seventh game of the second set, and then wasted a golden opportunity to get back into the match in the following game as he returned Haas’ serve into the net on his break point chance. The German held and proceeded to close out the match on his third match point.

“I think he's just a great competitor,” said former World No. 6 Haas, who improved to a 7-3 lifetime record against Roddick. “He really makes you win every point... Today was one of the matches where I won the majority of the important points. When I broke him a couple times today, I really played some great points, backhand and forehand passing shots and forehand lobs, and that was really the only difference today.”

The 29-year-old German is playing in his fifth tournament since undergoing shoulder surgery last November, and had not advanced past the second round prior to this week. He is making his 10th appearance at Indian Wells, and made his best run last year when he reached the quarterfinals.

Two-time semifinalist Roddick, who had gotten off to his best start in three years with titles in San Jose and Dubai, said: “I don't think my confidence is really affected.  I felt like I was hitting the ball well. I just needed to kind of get into it a little bit more and bear down on the big points, which I didn't do today.”

Twelfth-seeded Chilean Fernando Gonzalez followed Roddick out of the draw in a loss to another former Top 10 player, Croat Mario Ancic, who battled to the 7-5, 3-6, 6-3 victory. Ancic is also on the comeback trail from injury; he missed nearly six months last year with mononucleosis and the first month of this season with a stomach illness. He reached the Marseille final in February to climb back into the Top 100 of the South African Airways ATP Rankings.

A number of other seeds were also fiercely tested in their second round openers, but pulled through for the three set wins.

Top Brit Andy Murray, the No. 11 seed, came back from a loss of a set to defeat Austrian Jurgen Melzer, 3-6, 6-3, 6-3. Meanwhile, two others were pushed to a third-set tie-break: seventh-seeded Argentine David Nalbandian defeated Latvian teenager Ernests Gulbis 6-4, 4-6, 7-6(4), and Spanish No. 15 seed Tommy Robredo toiled for more than three hours against Chilean Nicolas Massu before prevailing 6-4, 5-7, 7-6(5).
