CHENNAI, India — Ivo Karlovic of Croatia became the latest seeded player to lose at the Chennai Open, falling 7-6 (4), 6-4 to Indian wild-card Somdev Devvarman in a quarterfinal on Friday.

Third-seeded Marin Cilic of Croatia overcame Janko Tipsarevic of Serbia 6-4, 0-6, 6-4. He will next face eighth-seeded Spaniard Marcel Granollers, who beat Lucas Dlouhy of the Czech Republic 7-5, 2-6, 6-4.

The 202nd-ranked Devvarman reached his first ATP semifinal in his hometown tournament. He will play fifth-seeded Rainer Schuettler, who beat fellow German Bjorn Phau 6-2, 7-5.

"It was a huge mental game," Devvarman said. "I'm pleased at the manner in which I played my baseline game and managed to serve well. ... I saw Karlovic struggle. I was conscious of the fact that the heat would affect him more than it would bother me."

Devvarman earned the match's only break in the 10th game of the second set. The 23-year-old won NCAA titles in 2006 and '07 playing for the University of Virginia. He is the first Indian player to reach the Chennai semifinals since Leander Paes in 1998.

The hard-serving Karlovic described his performance as "amazingly bad."

"It was a horrible display as I just couldn't put the ball in court," Karlovic said. "I can't remember when I last played like this."

Cilic, the highest seeded player remaining after top-seeded Nikolay Davydenko pulled out with a heel injury and No. 2 Stanislas Wawrinka was knocked out in the opening round, broke Tipsarevic in the third game en route to winning the first set.

The seventh-seeded Tipsarevic bounced back to dominate the second before Cilic regained his composure in the third, capitalizing on his opponent's errors to earn the decisive break in the ninth game.

"Janko started playing much better and got the mental advantage after breaking me early in the second set, while I went a bit down with too many errors," Cilic said. "I got my rhythm back and started serving well again in the third set, and that clinched the result for me."

The 32-year-old Schuettler broke Phau twice to win the first set and then rallied from a 5-2 deficit in the second to beat his training partner.

"We're good friends, have played each other often and even had a hit out this morning," said Schuettler, who was a finalist here in 1999 and a semifinalist at Wimbledon last year.
