Fulmer was added to the Tigers' 40-man roster Friday.
Fulmer, one of the pieces acquired through the Yoenis Cespedes trade, was excellent in his limited time with Double-A Erie, recording a 2.84 ERA and 1.09 WHIP coupled with a 33:7 K:BB in 31.2 innings. However, he's unlikely to make any noise with the Tigers this year, so it seems likely this move was made in order to protect him from being selected in the upcoming Rule 5 Draft.
