6'1" 165 lbs. lean frame with room to add strength. The Skippers and Tigers matchup last Tuesday turned out to be one of the better pitched games so far this spring, and Marse was really good for Mandeville. It was an efficient outing for the uncommitted junior right-hander, as he ended up earning the tough loss, after tossing 7 innings and giving up 1 R and 0 ER on 3 H with 2 BB and 8 K's. His FB sat 79-84 mph and he was able to induce a couple of swings & misses at the top of the zone, while also showing feel for a 70-74 mph SL and 73-75 mph CH.
