ATLANTA--John Isner kept his Atlanta ATP title defense on track Friday with a 7-6 (10/8), 6-4 quarterfinal victory over Australian Marinko Matosevic.
A day after Isner fired 30 aces and still had to fight off two match points in a second-round win over Robby Ginepri, the towering American fired 17 aces and won 84 percent of his first-serve points in his win over Matosevic.
Isner was broken in the first game of the match, but kept his composure to take the opening set in a tie-break, saving a set point along the way.
He converted two of his own five break chances to seal the win, breaking for a 4-3 lead in the second set and pounding an ace on his first match point.
"I knew he was struggling out there a little bit and he knew I was struggling out there a little bit," Isner said. "A lot of times those situations are a big advantage for me because I can muster up enough energy to pop some big serves in.
"The beginning of the second set it felt like someone put us in the oven. It was rough. There's only one option for me there: play big and play aggressive. A lot of times it works out."
Isner, the champion in Atlanta in 2013 and runner-up to Mardy Fish in both 2010 and 2011, will face fellow American Jack Sock for a place in the final.
Sock rallied from an early 1-4 deficit to dispatch Slovakian Lukas Lacko 7-6 (8/6), 6-2.
Sock, enjoying the best season of his career, was in his fifth quarterfinal of 2014.
"I had a pretty rough start," Sock said. "He came out keeping the ball really deep, keeping me off the baseline and out of my forehand. I broke back for 5-4 and the momentum shifted in my favor."
Israel's Dudi Sela booked a semifinal berth with a 7-5, 1-6, 6-2 upset of Canadian fourth seed Vasek Pospisil.
Sela notched his 100th tour-level match win and reached the fifth ATP semifinal of his career.
He'll face Germany's Benjamin Becker, a 6-4, 6-2 winner over Thiemo De Bakker of the Netherlands.
