Mardy Fish retired from his first-round match at the Swiss Indoors against fellow American James Blake on Tuesday after just one game because of a hamstring injury. Fish, who entered the tournament as the fifth seed, held serve in the opening game and lost the first point of the next game when he decided he couldn't continue due to pain in his left leg.
Fish is hoping to qualify for the season-ending ATP World Tour Finals for the first time. He is currently in the eighth and final qualifying spot for the tournament starting in London on Nov. 20. Although Fish cannot be overtaken this week, the last qualifying tournament is next week in Paris.
