JOIN USTop seed John Isner booked his spot in his eighth Atlanta Open final, defeating Aussie Matthew Ebden 6-4, 6-7 (6/8), 6-1 in the semifinal.
The hard-serving Isner avenged his only loss to Ebden in five career ATP Tour meetings when the Aussie beat him earlier this year at the Australian Open.
"It was tough," Isner said. "Just like yesterday, I was able to get out early in the third set and that definitely took some pressure off.
"I'm very happy to be back in the final here."
In the final, the 33-year-old Isner will face fellow American Ryan Harrison, who beat Britain's Cameron Norrie 2-6, 6-3, 6-2.
Isner has won eight of his nine semifinals in Atlanta, and will look to improve his record of 13-12 in finals.
Isner appeared to be cruising to victory, leading by a set and up by a break, when the wheels almost fell off.
The fourth-seeded Ebden broke back in the second and then saved one match point in the ensuing tie-break when Isner flubbed a backhand return.
Isner rebounded by breaking Ebden twice in the deciding set. He smashed 26 aces, using the confidence from his victory at the Miami Open and run to the Wimbledon semifinals to win in exactly two hours.
Agut survives scare
Second seed Roberto Bautista Agut survived a scare against Serbian Laslo Djere before holding his nerve to win 6-7 (5), 6-4, 6-4 to reach Swiss Open final in Gstaad on Saturday.
Chasing his third title of the year, Bautista Agut raced to a 4-1 lead in the opening set but was soon pegged back by a determined Djere, who went on to force a tiebreak.
Djere dominated the tiebreak but eventually needed five set points to close out the first set.
Spaniard Bautista Agut responded by cutting down unforced errors in his game before converting a decisive break in each of the next two sets to book a place in Sunday's final.
Earlier in the day, world number 84 Matteo Berrettini reached his first tour final with a 6-4, 7-6 (6) win over Estonian Jurgen Zopp.
