Richard Gasquet is through to the final of the Mercedes Cup after rallying for a 6-7 (3-7) 6-2 6-3 victory over sixth-seeded Agustin Calleri of Argentina on Saturday.

With the victory, the second-seeded Frenchman appears to be finally living up to his ranking.

Gasquet began this season ranked inside the top 10 and appeared ready to establish himself further following a 2007 campaign that saw him win a title, reach two other finals and make a run to fourth round at Wimbledon.

The first six months of the 22-year-old's year have been forgettable, however, as he entered this red clay event just 16-13 without a semi-final appearance to his credit.

Currently ranked 15th and the French number one, Gasquet can take major step toward turning things around Sunday when he faces Argentina's Juan Martin del Potro in the final.

Calleri, 31, was bidding for his first ATP final appearance since finishing runner-up to Nikolay Davydenko at New Haven two years ago.

While the veteran Calleri may represent Argentina's past, del Potro and upstart Eduardo Schwank provided a glimpse of the country's future in their semi-final clash.

In the end, it was the 19-year-old del Potro who moved through to his first career final with a 6-2, 6-4 victory over his eighth-seeded compatriot.

Schwank, 22, has surged from 171st to 62nd in the rankings since the start of the year and also was bidding for his first championship match appearance.

Gasquet, who won his only prior meeting with del Potro in 2007 at Indian Wells, will be gunning for the sixth title of his career on Sunday.
