Lack of Significant Closer Depth
Outside of the duo, Detroit’s other bullpen options are a bit of a mixed bag.
Bruce Rondon would be a hypothetical closer if he can regain his 2016 form.
The right-hander was arguably Detroit’s best reliever down the stretch last season, striking out 11.15 batters per nine innings while posting a 15.8 swinging strike percentage, a 0.96 WHIP and a 2.95 SIERA.
Those are closer-like numbers if Rondon can replicate them, but he’s struggled so far in 2017 (six runs and four hits allowed in 1.1 innings) with the Tigers.
All four are largely untested though, and seem better suited to pitching multiple innings than closing.
