BOGOTA, Colombia (AP) Top-seeded Ivo Karlovic of Croatia came back to defeat home-crowd favorite Daniel Elahi Galan 6-7 (12), 6-1, 6-3 to reach the quarterfinals of the Claro Open on Thursday.

The 23rd-ranked Karlovic served 28 aces and didn't allow a single break point against the 607th-ranked Colombian.

Karlovic, the runner-up last year in Bogota, will meet veteran wild card Radek Stepanek of the Czech Republic, who beat sixth-seeded Sam Groth of Australia 6-4, 6-0.

Third-seeded Adrian Mannarino of France also didn't concede a break point on his way to a 7-5, 6-3 win over Rajeev Ram of the United States, setting up a quarterfinal against Malek Jaziri of Tunisia, who rallied to defeat American qualifier Alexander Sarkissian 6-7 (1), 6-3, 6-2.
