ST. PETERSBURG (Agencies) - Marin Cilic won his first title of the season and the sixth of his career by beating Janko Tipsarevic 6-3, 3-6, 6-2 in the final of the St. Petersburg Open on Sunday. The 22nd-ranked Cilic, playing in his fourth final this season, broke in the sixth game of the first set. Tipsarevic, who won his second career title in Moscow last week, broke early in the second set to level. Tipsarevic saved two break points before the fourth-seeded Croat broke him with a precise backhand down the line in the sixth game of the third set. On his next serve at 5-2 down, Tipsarevic fell to 15-40, but fired an ace and served a winner to save two match points. But on the subsequent deuce, the 13th-ranked Serb returned wide and Cilic converted his third match point with a backhand winner. Tipsarevic took a medical time-out after the first game in the third set to have the back of his right leg massaged and receive treatment for a blister on the little toe of his right foot. Cilic said he used the time to gather his thoughts. Tipsarevic, who won his maiden title in Kuala Lumpur, Malaysia, on Sept. 26, said he was tired by the end of the match.
