ATLANTA (AP) — Top-seeded defending champion John Isner and Jack Sock each rallied Friday in the Atlanta Open to set up an all-America semifinal between the practice partners.

Isner beat Marinko Matosevic 7-6 (8), 6-4 in hot conditions, taking advantage of the Australian's mistakes to run his Atlanta record to 14-3.

Sock later topped Slovakia's Lukas Lacko, 7-6 (6), 6-2 after trailing 3-5 in the first set.

In the other quarterfinals, Germany's Ben Becker beat Dutchman Thiemo de Bakker 6-4, 6-2, and Israel's Dudi Sela topped fourth-seeded Vasek Pospisil of Canada 7-5, 1-6, 6-2.
