The Toronto Raptors confirmed Monday that they have exercised a contract option on forward Andrea Bargnani.

Bargnani, who turned 23 on Sunday, is committed to the Raptors through the 2009-10 NBA season. 

Financial terms were not disclosed.

Bargnani has averaged 10.8 points, 3.8 rebounds, 1.0 assist and 24.4 minutes in 143 games, including 55 starts, since he was drafted first overall by Toronto in 2006.

The stylish seven-footer increased that output in Toronto's seven pre-season games, averaging 14.7 points and 4.9 rebounds.

"Just a little bit more maturity, confidence, feeling something to prove — not just to people but himself," Raptors head coach Sam Mitchell said. "Last year, he hit some bumps in the road.

"But you know what? That is when you learn and that is when you grow.

"He has still got a lot of work to do. But we're very pleased and proud with the steps he has taken."

The Raptors open the regular season Wednesday at Philadelphia (7 p.m. ET).
