Top seed John Isner swept into the semi-finals of the BB&T Atlanta Open with a straight-sets win over Lithuanian Ricardas Berankis.
The big-serving American claimed a 7-6 (7/5) 6-4, one break of serve in the second set all he needed to book his place in the last four.
Isner's compatriot Denis Kudla joined him in the semis, the qualifier following up his victory over Jack Sock by knocking out Israel's Dudi Sela 7-5 6-0.
