Tommy Haas exits French Open

PARIS -- Tommy Haas' bid to become the oldest man in the French Open's second round since Jimmy Connors in 1991 ended after less than a set Tuesday because of pain in his right shoulder.

Now the question for the 36-year-old German, a four-time Grand Slam semifinalist, becomes how much longer he will put up with the injury.

"If it continues to go on like this, who knows? It's a tough task to continue and to see doctors every other week to try to just be able to play a tournament here or there or finish a tournament or finish matches now," Haas told The Associated Press. "We'll have to see. It's frustrating."

The 16th-seeded Haas stopped playing while leading 5-2 in the opening set of his first-round match at Roland Garros against 335th-ranked Jurgen Zopp of Estonia.

"I felt it on one shot at 5-2, and that was it. I felt a little something in the shoulder. I couldn't really do the motion anymore that I need to create power and to feel good," Haas said. "Nobody knows your body as well as yourself, so it's tough to understand from the outside. But I just know that something is not right. ... I need some rest and more rehab and will see if I can get it back on track again."

Haas, who reached the quarterfinals at last year's French Open, got to a career-best ranking of No. 2 in 2002. But he then missed all of the following year and part of 2004 because he twice needed surgery on his right shoulder.

At his last tournament, the Italian Open, Haas quit after the first set of his quarterfinal May 16 because the shoulder was bothering him.

"The wear and tear and the recovery process for that shoulder is obviously much, much harder to do," Haas said. "With the history of problems that I've had, it's not too easy. But you try til the last chance you get, in order to get it back on track and just to see if you can play matches without too much pain."

Meanwhile, Andy Murray won his first match at Roland Garros in two years, beating Andrey Golubev of Kazakhstan 6-1, 6-4, 3-6, 6-3 Tuesday.

Moments after Murray's victory, he got an offer from a coach ... or at least from someone who might be a coach someday.

Before he walked off court, former player Fabrice Santoro interviewed Murray in front of the crowd at Court Suzanne Lenglen. One of the questions had to do with Murray's lack of a coach, with Santoro saying he had a list of candidates.

"Are you one of them, or not?" Murray asked.

"You want my card? I'll give you my card," Santoro responded, handing his business card to Murray.

The seventh-seeded Murray has been without a coach since he parted ways with Ivan Lendl in March. But with Lendl by his side, Murray finally won a major title at the 2012 U.S. Open. Then he won the big one nearly a year later, becoming the first British man to win the Wimbledon title since Fred Perry in 1936.

His next match at Roland Garros will be against Marinko "Mad Dog" Matosevic, a 28-year-old Austrian who beat Germany's Dustin Brown 7-6 (5), 6-4, 6-7 (1), 7-5 for his first Grand Slam win in 13 attempts.

Murray said Matosevic was a good guy, calling him an "interesting character, that's for sure." He said the Austrian is always ready to make others laugh.

Another seeded player in Haas' section of the draw, No. 21 Nicolas Almagro, also retired during a first-round match Tuesday, allowing 21-year-old Jack Sock, who's from Nebraska, to advance.

Almagro, a three-time French Open quarterfinalist, stopped while trailing 5-0 because of a left foot injury he said has been bothering him for six weeks. He was one of three men to defeat Rafael Nadal on clay this season.

In other matches, Grigor Dimitrov, the 11th-seed who reached the quarterfinals at the Australian Open, lost to Ivo Karlovic of Croatia 6-4, 7-5, 7-6 (4).

Dimitrov has never fared well at Roland Garros, getting only to the third round in 2013.

Former top-ranked player Lleyton Hewitt also lost, but No. 5 David Ferrer of Spain, No. 12 Richard Gasquet of France, No. 19 of South Africa, No. 28 Philipp Kohlschreiber of Germany and No. 32 Andreas Seppi of Italy all won.
