The Mariners have re-signed Oliver Perez to a one-year, $1.5 million contract with an additional $600,000 in performance bonuses.

Perez, 31, would likely have attracted considerable attention on the free agent market.

"He did a very nice job in helping solidify our bullpen after his call-up last summer," Jack Zduriencik said. "As a veteran left-hander and one that had adjusted very nicely to his new role, we are looking forward to his contributions as we go into the 2013 campaign."
