WINSTON-SALEM (AP) -- Defending champion John Isner advanced to the Winston-Salem Open final Friday, beating France's Jo-Wilfried Tsonga 3-6, 7-6 (7-3).
Isner, seeded third and ranked 10th, will face seventh-ranked Tomas Berdych of the Czech Republic, a 6-4, 6-3 winner over seventh-seeded Sam Querrey in the final hard-court tournament before the U.S. Open.
Isner, from nearby Greensboro, had 24 aces against the top-seeded Tsonga to reach his fourth final of the season. The American won the grass-court event last month in Newport. R.I.
Isner also improved to 3-1 against Tsonga, including two wins this year.
Berdych, seeded second, overcame 18 aces by Querrey by breaking his serve five times, including the final two games in both the first and second sets to advance to his third final of the season.
