Prep Baseball Report Minnesota

The Prep Baseball Report Minnesota's Unsigned Senior Showcase took place on August 23, 2015 at Vet's Field- Minnetonka High School. The showcase featured uncommitted prospects from the 2016 class who showcased their talents in front of our scouting staff, college coaches, and professional scouts.

Today we take a look at the pitchers who participated in the event. The top pitching prospect at this year's MN Unsigned Senior Showcase is Eden Prairie right-hander Trevor Divinski. Divinski has slowly been working himself back into shape after a Spring lay-off with minor shoulder issues. Wide shouldered with present strength; his better days are definitely ahead of him. Solid arm action with feel for secondary pitches- it's easy to dream on him being a 90+ arm at the college level.
