Colin Streff is a 2021 LHP/OF with a 5-9 175 lb. frame from Marion, IA who attends Linn-Mar. Medium frame with a slender build and room to fill. Ran a 7.81 second 60-yard dash. Primary lefthanded pitcher with a quick side step delivery into a medium belt high leg lift. Compact arm action in the back and into a three-quarter slot at release. Stays square to the plate at gather with a medium stride down the mound. Creates sinking life through the zone on the fastball sitting in the mid-70's and touching 78 miles per hour. Works pitches away from righthanded hitters. Looser sping 1-to-7 curveball with some depth that will continue to develop. Lefthanded hitter with a closed off stance and high hand set.
