Marlins sign reliever Rauch to one-year contract

MIAMI -- A youthful Marlins bullpen added some veteran experience on Tuesday with the signing of right-hander Jon Rauch to a one-year contract. To make room on the 40-man roster, outfielder Bryan Petersen was designated for assignment.

Rauch gives the Marlins an option to either close or serve in a setup role to Steve Cishek, who became the closer in the second half of 2012. The 34-year-old Rauch is a 10-year veteran who made 73 appearances with the Mets in 2012, going 3-7 with a 3.59 ERA. He added four saves.

A towering 6-foot-11, Rauch has a combined 3.61 ERA in 260 games over the past four years.

The signing of Rauch comes a day after a report that Miami was near a deal with Jose Valverde. The Marlins were not on the brink of adding Valverde, but it was clear the team had targeted a veteran reliever to help a young bullpen.

Since 2006, Rauch leads the Major Leagues in appearances (507) and relief wins (34). In his career, Rauch has pitched for the White Sox, Montreal/Washington, Arizona, Minnesota, Toronto and the Mets. He has 62 saves in 93 chances.

Petersen became expendable because Miami has a surplus of center-field options, including Justin Ruggiano and Gorkys Hernandez. Christian Yelich, the Marlins' No. 2 prospect, is also a center fielder.
