Rockies extend Belisle through 2013 season

DENVER -- The Rockies and right-handed reliever Matt Belisle agreed on a one-year contract extension through 2013, with a mutual option for 2014, the club announced Friday morning.

Belisle was under contract for 2012 at $3.775 million. He will make $4.1 million in 2013, and a mutual option for 2014 is worth $4.25 million, or a $250,000 buyout.

Last season, Belisle, 31, went 10-4 -- a career high for wins in a season -- with a 3.25 ERA in 74 appearances. Belisle had appeared in a career-high 76 games the previous year, and over the last two years is 17-9 with a 3.07 ERA.

"Matt is one of our core leaders, and we are extremely happy that he will remain a Rockie, hopefully for many years to come," Rockies general manager Dan O'Dowd said.

This is the third time Belisle and the Rockies have reached an agreement in about a year. He signed a one-year deal last winter to avoid arbitration, then he and the Rockies worked the agreement into a two-year, $6.125 million contract.

Belisle, who joined the Rockies as a non-roster invitee in 2009, is 36-32 with a 4.48 ERA, 401 strikeouts and 131 walks in 306 career appearances, including 43 starts, with the Reds (2003, 2005-08) and the Rockies.
