NEW YORK - Former top-10 player Mardy Fish pulled out of the US Open yesterday, according to the US Tennis Association, the latest setback in his bid to make a comeback on tour after dealing with heart issues.
The USTA said the 31-year-old American cited "personal reasons" for his withdrawal. The draw for the year's last grand slam tournament is today, and play begins Monday.
Fish has missed months of action at a time over the past two seasons.
On Tuesday, he stopped playing in the third set of his match against Jarkko Nieminen at a hard-court tournament in Winston-Salem, North Carolina, because of heat stroke.
Fish has played only eight matches on the ATP World Tour in 2013, going 3-5. He skipped all of the grand slam tournaments this season while entering only five other events on the main tour.
A year ago, Fish reached the fourth round at the US Open but withdrew before he was to face Roger Federer at that stage, saying it was for "precautionary measures" on doctor's orders and missed two months earlier last season because of an accelerated heartbeat.
The night after he lost a match at Key Biscayne, Florida, in March 2012, Fish's heart started racing uncontrollably.
That May, doctors induced extreme palpitations to try to pinpoint the problem. He returned for last year's Wimbledon.
Earlier this month, Fish spoke of the difficulties he's faced the last two seasons.
"I struggled mightily during the US Open last year. So those sort of post-traumatic experiences that I've had — that I have now — are what I need to get over right now," he said.
