(CNN) -- Andy Roddick had to dig deep before beating unseeded Israeli Dudi Sela to claim the China Open title in Beijing on Sunday.
Roddick was all smiles after landing his third ATP Tour title of the year.
The second-seeded American went into the final as hot favorite against the world-ranked 92 Sela, but after dropping the second set prevailed 6-4 6-7 6-3 for his third ATP title of the year.
In the women's tournament, top seed Jelena Jankovic later powered to victory in her final, thumping Russia's Svetlana Kuznetsova in straight sets.
World number two Jankovic, last year's losing finalist, overcame her Russian opponent 6-3 6-2.
Earlier, Sela playing in his first ATP final after beating top seed David Ferrer of Spain in his opening match, pushed Roddick all the way after dropping the first set.
After the Roddick broke serve early in the second set, Sela broke back in the sixth game. After a double fault and then a missed shot at the net -- which cost the American the game -- Roddick teed off and smashed a tennis ball high over the crowd and out of the two-tiered Beijing Tennis Center.
In the second-set tiebreaker, Roddick failed to close out Sela. With Roddick serving and leading the breaker 6-4, Sela won four straight points to take the set. Sela raced to his chair, sat down quickly and clenched his right fist.
In the final set, Roddick broke Sela in the sixth game and then finished the match with an ace.
Roddick claimed titles in San Jose, California and Dubai earlier this season, but suffered a mid-season slump. After skipping the Beijing Olympics, held at the same venue as this week's tournament, he played well at the U.S. Open, where he lost in the quarterfinals to Novak Djokovic.
