Ryan Harrison moved into his first ATP World Tour final, setting up a clash against Nikoloz Basilashvili in the Memphis Open decider.
Harrison progressed at the ATP 250 event with a 6-4 6-4 win over Donald Young in an all-American semi-final on Saturday.
The 24-year-old broke serve three times to seal victory in one hour, 30 minutes on the hard-courts in Tennessee.
Awaiting him in the decider is Basilashvili, who beat Mikhail Kukushkin 7-6 (7-5) 6-1.
The Georgian was dominant but was almost made to pay for missed chances, winning the first set in a tie-break after converting just one of 10 break points.
He lost just one point on serve in the second set to reach a second ATP final, although like Harrison he is eyeing a first title.
