    A two-way player for Xavier, Grammes has a huge fastball that was touching triple digits last summer in the Cape Cod League and has regularly been in the mid-90s this spring in a starting role, getting up to 97 regularly. Grammes pairs that with a hard, mid-80s slider that’s inconsistent but flashes above-average potential when he is on top of it. He also infrequently throws a firm, mid-80s changeup. The limiting factor for Grammes on the mound is his well below-average control. Over three years with Xavier—including his first 12 starts and 58.2 innings this spring—he’s walked 6.5 batters per nine innings. That stems from a max-effort delivery. Without radical improvement there and with his control, he profiles as a reliever on the mound. His production with the bat has been more impressive, statistically, during his time with Xavier with a .333/.395/.507 line and 23 home runs over 162 collegiate games, with impressive plate discipline numbers this spring. Grammes has good bat speed from the right side of the plate and runs well, though scouts are less convinced where his defensive home would be. Likely at third, second or in a corner outfield spot.
