Isner reaches Cincinnati final
John Isner followed up his victory over Novak Djokovic by beating Juan Martin del Potro to reach his second Masters series final in Cincinnati.
American tennis reached a historic low on Monday when Isner dropped out of the top 20, making it the first time since the rankings began that no US player has been at that level.
But the 28-year-old has answered the critics in the best possible fashion with one of the best weeks of his career.
Isner had already stunned world number one Djokovic in the quarter-finals and a day later he recovered from a seemingly impossible position to beat seventh seed Del Potro 6-7 (5/7) 7-6 (11/9) 6-3.
Del Potro broke to lead 5-3 in the second set and held a match point but served a double fault, Isner broke back and then took his fifth chance in the tie-break.
The Argentine looked lethargic and could find no way back after Isner won the first three games of the decider.
The 6ft 10in giant is taking confidence from his excellent form on home soil this summer.
Isner told Sky Sports: "As of right now I'm just very thrilled to be in the final. I've got to get myself ready and I know it's going to be another tough match.
"I certainly believe I can beat anyone, and if I can take that belief onto the court tomorrow I'm going to give myself a shot."
Isner's first Masters final came in Indian Wells last March, when he also beat Djokovic before losing to Roger Federer.
"I know I'm playing fantastic tennis," said Isner. "Whenever I get back home to the US I always play my best."
