NEW YORK – US ninth seed Andy Roddick made a shocking second-round exit from the US Open on Wednesday with Serbia's 44th-ranked Janko Tipsarevic firing 66 winners in a 3-6, 7-5, 6-3, 7-6 (7/4) victory.
Roddick, whose lone Grand Slam title at the 2003 US Open was the most recent Slam crown won by an American, suffered his only worse Flushing Meadows finish with a first-round exit in 2005.
Tipsarevic smacked 66 winners, hit 59 percent of his first serves and won 81 percent of his first-serve points to send off Roddick, who told the Serbian not to lose his next match.
"He said, 'If you lose early I'm going to freaking kill you," Tipsarevic said.
"He played great," Roddick said. "I told him, 'Too good.'"
Tipsarevic next faces French 17th seed Gael Monfils, who celebrated his 24th birthday by ousting 121st-rated Igor Andreev 6-3, 6-4, 6-3. The Russian, slowed by knee and ankle injuries, had won four of five prior matches against Monfils.
"He's maybe after (top seed Rafael) Nadal the guy who is moving the best on the court, playing really well," Tipsarevic said. "If I play like I did today, I might have a chance to win."
Tipsarevic said talent played a bigger role than risk.
"I wasn't feeling I played too risky. I just played good," Tipsarevic said. "Keeping this level is really hard. Only champions can do that."
After splitting the first two sets, Roddick fell behind in the third but gathered energy after a foot fault controversy.
With Roddick serving down 2-5 in the third set, a line judge called a foot fault that television replays showed was correct.
But when Roddick asked her which foot he committed the violation with, she mistakenly said the right, giving Roddick something to verbally complain about into the next set.
"Why don't you get some umpires who know what they are doing?" Roddick said. "Try 1-800-Rent-A-Ref!"
"My right foot? Really? Right foot?" Roddick yelled. "Had time to think about how that is physically impossible?"
Roddick battled back to hold serve but Tipsarevic battled through five set points before finally smacking a backhand down the line winner past Roddick to claim the set.
"I'm either really talented or she messed up really bad. That's ridiculous. I think we both know that's ridiculous," Roddick said to the chair umpire after the set, muttering an obscenity as he walked to the locker room for a shirt.
After the match, Roddick was only mildly calmed down about the call.
"I expect my umpires to know their right foot from their left," Roddick said. "It was the fact that I couldnt get her to admit it was the wrong foot infuriated me. I have trouble when they stick to an argument that's wrong.
"It was probably a very correctable mistake and I probably let it get to me more than it should have.
"It's just, in the moment, I was just stupified.
"A lot is going to get written about it but it had zero impact on the match."
Roddick, who won 17-of-17 first-serve points in the fourth set, fell behind 3-2 in the tie-breaker when he sent a backhand beyond the baseline. Tipsarevic then won the next two points on his serve for a 5-2 edge.
Roddick hit a backhand volley winner and Tipsarevic hit a backhand long to pull the American within 5-4, but the Serbian smacked a service winner to reach match point and won it after three hours and 18 minutes with a backhand winner.
