The Arizona Diamondbacksagreed with free-agent reliever Tyler Clippard on a two-year contract Monday.
The deal is worth $12.25 million, a source confirmed to ESPN's Jerry Crasnick. The deal includes a base salary of $4.1 million in 2016 and $4.15 million in 2017, as well as a signing bonus of $4 million.
FoxSports.com was first to report the deal.
Clippard, who turns 31 later this week, went 5-4 with a 2.92 ERA and 19 saves last season with the Oakland Athletics and the New York Mets. The two-time All-Star joins an Arizona bullpen that features closer Brad Ziegler, who had a career-high 30 saves last season, and converted starter Daniel Hudson, who posted a 3.86 ERA last year in his first full season as a reliever.
Clippard helped stabilize the Mets' bullpen last season while leading into closer Jeurys Familia after he joined the club in a July 27 trade with the Athletics. He allowed one run in 19 2/3 innings over his first 20 appearances while serving as Familia's primary setup man.
Clippard took a step backward in the final weeks of the regular season and the postseason. He had a 6.75 ERA in eight postseason appearances.
Nonetheless, he was the only pitcher in the majors to appear in at least 69 games in each of the past six seasons.
