PHILADELPHIA (AP) -- Ruben Amaro Jr. will replace Pat Gillick as general manager of the World Series champion Philadelphia Phillies on Monday.

Amaro just completed his 10th season as assistant GM and was considered the front-runner for the job after Gillick said last year this would be his last season.

The Phillies will introduce Amaro at a news conference Monday, just five days after the team beat the Tampa Bay Rays to capture the second championship in franchise history.

Amaro got the nod over Mike Arbuckle, who spent the last 15 years with the Phillies. Arbuckle was the director of scouting for his first seven seasons in Philadelphia, and became an assistant GM in October 2001.

Amaro, 43, joined the Phillies immediately after his playing career ended in 1998. He worked under former GM Ed Wade for seven seasons and the last three with Gillick.
