MINNEAPOLIS — Joba Chamberlain received his long-awaited promotion, and the rookie right-hander will make his first start for the Yankees at home in the Bronx.

Manager Joe Girardi said the 22-year-old will take the mound at Yankee Stadium on Tuesday night against Toronto and be limited to 65 or 70 pitches.

After deliberating about the decision during New York's off day Thursday and consulting with general manager Brian Cashman, Girardi said today he decided to keep Andy Pettitte on his regular throwing schedule and use the left-hander for Monday's series finale against the Twins.

New York has been grooming Chamberlain for the rotation since selecting him out of the University of Nebraska with the 41st overall pick in the 2006 amateur draft. After posting a 0.38 ERA in 19 appearances last season, Chamberlain had a 2.28 ERA in 20 games out of the bullpen this year.

After throwing on the side Friday, Chamberlain was excited.

"I feel great. Everything is going well. Every `i' is dotted, and every 't' is crossed, so far," Chamberlain said.
