The 37-year-old to be had a fantastic season with the Tampa Bay Rays in 2012, before adding another good season in 2013. In his most recent campaign, the 2012 All Star went 5-4 with a 3.38 ERA and 37 saves in 68 games with the Rays (113 ERA+). He did a fantastic job getting hitters to punch out (11.1 K/9 rate), while for the most part keeping the hitters off base via the free pass (4.9 BB/9 rate). Over the past two years, Rodney has a 1.91 ERA and 85 saves in 144 games with the Rays (201 ERA+).
It'll be hard to continue at that rapid pace that Rodney has had, but nonetheless he should be a force in the back of the Mariners bullpen that has needed some bolstering. The Mariners' relief corps posted the second-worst relievers' ERA in 2013 with a 4.58 mark. Rodney is expected to help bring that number down as the Mariners attempt to contend in the American League West in 2014.
