ST. PETERSBURG, Russia (AP) Mikhail Kukushkin won his first title in his first attempt, upsetting top-seeded Mikhail Youzhny 6-3, 7-6 (2) Sunday in the final of the St. Petersburg Open.
Kukushkin's previous best result was a semifinal appearance in Moscow last season, where he lost to eventual champion Youzhny in straight sets.
The 88th-ranked Kukushkin broke the 10th-ranked Youzhny twice in the first set. After an exchange of breaks midway through the second set, Youzhny broke in the 11th game and served for the set. But Kukushkin broke back to force a tiebreaker.
In the tiebreaker, Kukushkin took a 6-2 lead and sealed the win on his first match point.
``I won because I was running for every ball and played solid tennis,'' Kukushkin said. ``I do not remember how I broke back in the last game, but I'm happy with the way I played on the tiebreaker.''
Youzhny, who saved a match point in the quarterfinal and four more in the semifinal, said he was exhausted going into the tiebreaker.
``Mikhail has played a perfect match today and he deserved the victory,'' Youzhny said. ``He played better on key points and it was tough for me to concentrate while receiving in the second set.''
Kukushkin is expected to move to a career-high top 60 in the rankings next week.
