The Prep Baseball Report Unsigned Senior Showcase on Oct. 16 at The Max featured more than 110 prospects from across the state. Already we highlighted the top 30 overall prospects at the event, along with all the position players

Now we take a closer look at the pitchers. Below we examine the pitchers at the event:

1. Mike Yacko, RHP, Oak Lawn HS
Yacko is a 6-foot, 180-pound right-handed pitcher with an athletic build, a high ¾ arm slot, and smooth rhythm.  Yacko impressed with his ability to command three pitches, all with heavy downward action. Yacko’s fastball sat in the 86-87 mph range, and it featured downward run and sink.  He also showed a slider that had sharp, late action, in the 74-75 mph range. Yacko’s slider can be a legitimate swing-and-miss pitch at the next level.  Yacko, who hides the ball well, also throws a firm changeup that exhibited sink down in the zone. In all, Yacko’s ability to command three pitches – all with movement – should make him one of the most coveted unsigned arms in the Class of 2012.
