10/21/18 - Wiry, 5-foot-10, 140. Grinsell has an athletic build.   This projectable two way player is as loose and natural as they come.  On the mound, his delivery is smooth and easy from the windup, gathering over the rubber and releasing from a ¾ slot. His fastball has some straight fade on his arms side.  His curveball is lite but shape and spin are there.  Like the fastball, his changeup has fade life to his arm side.  From the stretch, he rushes a bit with the use of a slide step which hinders velocity, but the zone feel remains good.  In the field, Grinsell possesses good rhythm with a long loose release and solid carry.  He plays the arm side run from the outfield well.  Size and strength gains might potentially shift him to corner outfield, but his quickness makes a stay in CF prominent. Grinsell stands in at the plate with an open stance, tapping back to straight knee to knee and then striding. He shows heavy hand load, tipping the barrel behind his head, providing major separation.   He hits against a firm front side with some natural loft. His barrel is free and easy with whip at the end. He makes consistent hard contact and flashes raw power. He is a projectable 5 tool type player.
