Gregory Soto

Soto was decent last year once he took over as the closer, posting 18 saves on the season with a 3.39 ERA. But his walk rate was an abysmal 14.5%, leading to a 1.35 WHIP, which just isn't sustainable. The Tigers don't have an elite bullpen but Michael Fulmer and Jose Cisnero can close in a pinch. With the uncertainty and Soto's control issues, don't bank on more than 20 saves.
