Former Georgia tennis player John Isner had an inspired run at the Atlanta Tennis Championships, but lost in the final Sunday to fellow American Mardy Fish during a three-set match in the scorching summer heat.

Fish topped Isner 4-6, 6-4, 7-6 (7-4) in the 2 hour, 45 minute match where the on-court temperature hovered near 150 degrees. Fish, who now has won two tournaments in a row, was ranked No. 6 in the tournament, while Isner was the No 2 seed. Fish beat top seeded Andy Roddick to reach the finals.

Isner is 1-3 in finals this season, but gained his greatest fame during his historic first-round win at Wimbledon last month.

“It’s disappointing,” Isner told the Associated Press. “I’ve made four finals this year and I’ve lost my last three, all in three sets. That’s tough to swallow but it hasn’t stopped me from progressing.”
