Teenager Taylor Fritz beat Benjamin Becker of Germany 6-4 5-7 7-6 (7-5) on Friday at the Memphis Open, becoming the youngest American to reach an ATP semi-final since 1989.

Fritz, who turned 18 on October 28, used his big serve and strong forehand to advance to his first career ATP semi-final as the youngest American since Michael Chang won Wembley in 1989 at the age of 17

“It feels incredible,” Fritz said.

“You know it’s a great milestone. I always say this is reassuring to know that I’m doing the right thing and I’m on the right track.”

The teenager, in the event as a wild card and ranked No.145 in the world will play Ricardas Berankis of Lithuania on Saturday.

Berankis upset third seed Donald Young 7-6 (7-3) 6-1.

Fourth-seeded Sam Querrey beat Japanese qualifier Yoshihito Nishioka 6-3 6-4 in the other quarterfinal and likely awaits Japanese to seed Kei Nishikori who will play Mikhail Kukushkin in the remaining quarter-final.
