Winston-Salem, N.C. - Mardy Fish, who is in the middle of coming back from a heart issue, advanced against Evgeny Donskoy in the first round of the Winston-Salem Open on Sunday. The American won 6-3, 3-6, 6-1.

Fish accepted a wild card to enter the field of the last warm up tournament prior to the U.S. Open this year. It was in the 2012 Open where Fish was forced to pull out of the tournament due to a heart problem. He was set to play Roger Federer in the round of 16 of that event.

Fish has only been able to compete in 5 singles events since prior to the Winston-Salem Open and has seen his ranking plummet to 129 due to inactivity.

On Sunday, he faced the young Russian who has spent a good portion of the summer playing in Challenger events.

Fish only placed 56 percent of his first serves in play in the match but won 76 percent of those. He had 8 break opportunities, breaking Donskoy 4 times in route to the victory.

Fish will move on to face Jarkko Nieminen of Finland on Monday. Nieminen was ranked 39th in the latest world rankings.

Other winners in Winston-Salem included Guillermo Garcia-Lopez, Robin Haase, Alex Bogomolov, Jr. and Yen-Hsun Lu.

One of last years surprises, David Goffen, qualified for the main draw on Sunday.
