He wasn't much better in Toledo. He posted a 10.13 ERA over six appearances, with six walks in 5 1/3 innings. He did record nine strikeouts.
Still, the Tigers are going to see if he can recapture his form. Rosenthal posted 93 saves and a 2.65 ERA for the Cardinals from 2014-15, while striking out well more than a batter per inning. He was an All-Star in the latter year.
With the trade deadline two weeks ago, there's an off-chance Rosenthal could turn himself into an asset. If his struggles continue, the Tigers will simply cut bait.
To create room for Rosenthal on the roster, the Tigers optioned pitcher Gregory Soto to Toledo.
