Minutes before Thursday's series finale with the Cubs went into a brief rain delay, the Phillies officially announced a two-year contract extension for second baseman Chase Utley.
A league source confirmed to CSNPhilly.com's Jim Salisbury that the two-year deal is worth $27 million, but if Utley stays healthy, it can max out to five years, $75 million.
The contract specifics were first reported by Fox Sports' Ken Rosenthal.
The two-year deal runs through the end of the 2015 season and includes three vesting/club options each worth $15 million on top of his two guaranteed years and that each of his options will vest at 500 plate appearances.
“Chase epitomizes everything we expect our Phillies to be,” GM Ruben Amaro Jr. said in a statement. “As we've said before, we see Chase as a true Phillie for life. This contract moves us toward that end. We couldn't be more pleased.”
Utley, 34, has hit .280 with 15 homers and 44 RBIs in 85 games this season. His .513 slugging percentage leads all major-league second basemen, and he ranks third at his position in home runs despite missing a month with an oblique injury.
Utley, who was in the final year of a seven-year, $85 million contract, missed 138 games in 2011 and 2012 with a chronic knee condition. He changed his offseason regimen this past winter to stay more active and, as a result, has been able to stay on his legs and regain his power stroke.
Of note, relative to the vesting options, Utley hasn't exceeded 500 plate appearances in a season since 2009.
