06/29/2016 - 2016 Under Armour Showcase: Baseball Factory's National West Diaz continues to show that he can compete at a high level. He works though a short/compact delivery and gets strong glove-side lead, driving downhill off of the bump. He locates well and works to keep the ball down in the zone. FB cracks the mitt at 83 mph while showing run. Curveball has 10/4 shape with good action. He pounds the zone and challenges hitters to swing the bat. Diaz has upside and will be a reliable arm that will eat up innings.
