Mario Ancic has retired at age 26 to become a lawyer. The former No. 7 and 2004 Wimbledon semifinalist is currently working at a law firm in Croatia. He retired due to chronic back problems. "I can't stand it any more. I have finished my career. I'm forced to quit because nature has decided it's time. My back can't withstand the effort of professional tennis," said Ancic, who helped lead Croatia to the 2005 Davis Cup title.—Matthew Cronin
