Coming off a reaching the round of 16 at Wimbledon, the 6-foot-11, hard-serving Karlovic had 23 aces, ending the match with one down the middle at 133 mph.

Karlovic will face No. 4 seeded Jack Sock, from the U.S., after he advanced when qualifier Jan Hernych, of the Czech Republic, retired with an injury in the second game.
