SP Michael Lorenzen
Another player that showed up to camp in great shape, Lorenzen is a high-upside signing starting pitcher. The Tigers think they can utilize Chris Fetter and his staff to try to get the most out of him. Since he's only signed on a one-year deal, he could easily be a trade chip at the deadline.
Lorenzen seemed to figure some things out toward the end of last season with the Angels. He had a 2.36 ERA in his last five starts. According to an article from Cody Stavenhagen of The Athletic (subscription required), Lorenzen made some changes last season after coming off an injury.
He changed his arm slot and started attacking hitters based on their handedness—fastball/slider to righties, fastball/changeup to lefties. The results were promising, striking out 30 in 26.1 innings pitched.
The Detroit Tigers are banking on what he showed last September being more the rule than the exception. With the coaching staff they have combined with Lorenzen's athletic ability, this could end up being a sneaky good signing that could net them a nice prospect at the deadline.
