Andy Roddick is strong favourite to claim the ATP Atlanta title when he takes on Gilles Muller in Sunday's final.
Roddick enjoyed one of his best wins of the season to edge past John Isner 6-4, 6-7(5), 6-4 late on Saturday night. Isner smashed down 26 aces but he was struggling with his returns and Roddick made him pay.
Conceding the second set on a tiebreaker was harsh on Roddick and he was relieved to prevent the match going into a decisive tiebreak by breaking in the tenth game of the final set.
"(Against) most people in a breaker, you can recover from losing one service point," Roddick said. "Against him, that's not necessarily the case. I'm not sure that I missed a ball besides a service return in the tiebreaker and still lost it. With his serve and weapon he has, a lot of times it's out of your control."
Roddick is a huge favourite against Muller having won their last three encounters on the tour. The tall left-hander served his way past Go Soeda in the semis, hitting 17 aces past the Japanese player for a 6-4, 6-3 win but Roddick will be a far tougher proposition.
