Rome ? Andre Agassi finally added an Italian Open title to his long list of championships.

As the only active player to have won each of tennis’ four Grand Slams, Agassi has few challenges left to conquer.

He managed to grab one of the few significant titles to elude him by beating Tommy Haas 6-3, 6-3, 6-0 Sunday to win the Italian Open 13 years after squandering a championship point in the event.

“It’s something you don’t really admit to yourself because it’s pretty much a disappointment when you came so close,” Agassi said of his desire to win in Rome.

“But you realize, as you size up all these tournaments outside the Grand Slams, that this has as much, if not probably more history, than all of them,” Agassi said of the event first played in 1930.

The seven-time Grand Slam champion used blistering groundstrokes and a fierce return game to frustrate the 24-year-old German. Agassi broke Haas’ serve seven times en route to winning the $2.57 million tournament.

Agassi held his usual position just inside the baseline for most of the match, while Haas opted to stand several feet behind the line, leaving himself vulnerable to Agassi’s well-angled shots.

The victory, the first for an American man in Rome since Pete Sampras won in 1994, ends Agassi’s long streak of misfortune in the event.

“It was an exciting week, and I’ll never forget this day,” Agassi said before receiving the winner’s check of $372,000. “I’ve waited a long time, and today is very special.

“I find that as I get older, it gets more difficult, which increases the challenge of it, which fuels the very thing that motivated me in the first place,” the 32-year-old Agassi said.
