Fish will meet second seed John Isner in the final after the towering American overcame stifling heat to beat unseeded South African Kevin Anderson 6-3, 6-7, 6-3.
Sixth seeded Fish had a poor service game, making just 40 percent of his first serves, but saved all three break points and broke Roddick in the only chance he received. Isner overcame seven break points and sweltering heat in his afternoon match against Anderson to advance to his fourth final of the year.
Isner had an opportunity to close out the match in the second set and escape the torturous heat when he held match point in the tiebreak but hit a forehand long and Anderson capitalised to send the match into a decider.
Both players battled fatigue in the final set, before Anderson double faulted to allow Isner to convert the only break point opportunity of the set and take a 5-3 lead, which he converted into victory.
Bopanna-Vliegen in final
Rohan Bopanna is one step away from winning his second ATP doubles title of the season after making the final of the Atlanta Tennis Championships along with partner Kristof Vliegen.|

Bopanna and Vliegen will next take on Americans Scott Lipsky and Rajeev Ram, who beat compatriots John Isner and James Blake 7-6 (7-5), 7-6 (7-5).
