CINCINNATI (Ticker) -- Lleyton Hewitt's 10-match finals winning streak came to an end.

No. 16 seed Carlos Moya upset the world's No. 1, 7-5, 7-6 (7-5) on Sunday to capture the $2.95 million Tennis Masters Series - Cincinnati.

Hewitt entered the match having won his last 10 finals, including Wimbledon last month, and had not lost in a final since falling to Wayne Ferreira in five sets in the 2000 Tennis Masters Series -- Stuttgart.

But the day belonged to Moya, the former world No. 1. He became the first Spaniard to win in Cincinnati in the 103-year history of the event and improved to 3-0 against Hewitt this season after a pair of clay court victories.

Moya earned his fourth title of the season and first Tennis Masters Series title since Monte Carlo in 1998. He won all six of his matches here in straight sets.

It was at Monte Carlo this season where Moya served notice that he has fully recovered from back problems that have plagued him since 1999. Moya lost to countryman Juan Carlos Ferrero in April, his best finish this season at a Tennis Master Series event.

The players traded breaks of serve under threatening skies and battled to a 4-4 tie in the first set when the match was halted by rain for two hours and 18 minutes. When play resumed, each player held serve before Moya came up with the decisive break in the 12th game to take the first set.

Moya was broken twice in his first four service games as Hewitt seemed poised to even the match with a 5-2 lead in the second set. But Moya broke twice before each player held to send the second set into a tiebreaker.

The tiebreaker was even at 5-5 when Hewitt double-faulted to give Moya a match point. Moya immediately capitalized with a service winner to win the title.
