DELRAY BEACH, Fla. (AP) Top-seeded Kevin Anderson quit his first-round match at the Delray Beach Open because of an injured right shoulder.
Anderson had just dropped the first set to 103rd-ranked American Austin Krajicek in a tiebreaker when he headed to the sideline. He packed his racket bag, shook his opponent's hand, tossed some used wristbands into the crowd and walked off.
Anderson won this tournament in 2012. He was forced to retire from his first-round match at the Australian Open last month because of an injured left knee.
Krajicek was down 3-0 in the first set but broke back on Anderson's increasingly weak serve. The 29-year-old South African was treated by the trainer after the seventh game and served for the set at 5-3 but failed to convert.
