Winston-Salem, NC (Sports Network) - John Isner upset Andy Roddick in Friday's all-American semifinal at the inaugural Winston-Salem Open, which is a final tuneup for the U.S. Open.
The fourth-seeded Isner upended the top-seeded Roddick in 7-6 (9-7), 6-4 fashion on the hardcourts at Wake Forest University. Isner broke Roddick for a 5-4 lead in the second set and then won the next game by swatting three aces to end the match.
Isner, who hails from nearby Greensboro, North Carolina, erased the struggling former world No. 1 Roddick in 1 hour, 34 minutes, as the two men combined for 18 aces, including 10 from the Day-6 loser.
The 6-foot-9 Isner is now 2-3 lifetime against Roddick, who prevailed in a bout at Indian Wells earlier this season.
Roddick hasn't reached a final since titling in Memphis back in February.
The 26-year-old Isner will appear in his eighth career ATP final, seeking a third title. The towering American captured a championship in Newport and was a runner-up in Atlanta last month.
Isner will face Julien Benneteau in Saturday's final after the French qualifier rallied past No. 10 seed Robin Haase of the Netherlands, 3-6, 7-6 (9-7), 7-6 (8-6), in a bout that lasted over two hours, 30 minutes.
Benneteau will be appearing in his fifth career final -- winless in the previous four -- and first since Marseille in February 2010.
Saturday's match will be the first meeting between Isner and Benneteau.
The Winston-Salem champion will collect $74,630.
