Querrey upsets Karlovic at Indianapolis championships

INDIANAPOLIS, July 26 (Reuters) American teenager Sam Querrey saved two match points to upset fifth-seeded Ivo Karlovic 5-7 7-5 7-6 at the Indianapolis championships today and reach his third quarter-final of the year.

''I don't think I've ever saved a match point on the ATP tour and won a match,'' Querrey told reporters.

Querrey, 19, reached the quarter-finals at Memphis and Las Vegas. He has also beaten Croatian Karlovic both times they have played.

Karlovic, 28, lost out on his second match point opportunity when serving at 6-5 in the third set tiebreaker by netting an inside out forehand. Querrey won the next two points, hitting a forehand winner for his first match point and then benefited from Karlovic netting a backhand return.

Querrey will play the winner of Thursday night's match between second-seeded James Blake and Ricardo Mello of Brazil.
