Trowbridge appeared in 16 games in the 2014 season for Central Michigan University, finishing with a 2-2 record, five saves, and a 2.59 earned run average. In 31 1/3 innings, he struck out 43, allowed 17 hits, and walked 24.
Here is a report of Trowbridge that was passed along to me:
“He’s a smaller lefty, probably 5’10″ realistically. Funky mechanics, straight over the top, drops his back shoulder hard, almost loses sight of the target because of how far he drops the shoulder, but the funkiness adds to deception and makes his stuff better.
Out of the pen (where I think he’s best), he’ll sit probably 88-93, around there. I’ve had him up to 95, but he’s been jerked around between starting and closing his whole career, so it’s tough to say where he’ll actually end up once permanently in the pen. If you made me guess, I’d say he’ll end up 90-93, topping 95 or so. FB has natural left handed life with the arm side run, but it does stay relatively flat (no sink). The arm slot helps him generate plane despite his size.
His best pitch is the curveball. It’s harder (79-83), with sharp 12-6 break. Throws it from same arm slot with same arm speed as fastball, and it’s absolutely nasty when it’s on. It’s a legitimate 6+ pitch when right, although he’ll leave it up from time to time.
At the end of the day, I think the upside here is a 7th inning guy, but realistically you’re looking at a LOOGY-type. He has a changeup, but it lags behind the FB/CB. The CB is very good, like I said, so he should find success against LHH.
