16. Koji Uehara
The 37-year-old is one of baseball’s most consistent relief pitchers, with a 0.92 WHIP and an average of 9.8 strikeouts per nine innings over the course of his four-year career. He’s also one of the most unsung, probably because he’s not a closer (14 career saves). He’ll serve as the bridge from the starters to the back of the bullpen, and it’s an important role in which he should thrive.
