5.18.16: At short, Grammes is very smooth and has a good understanding of how much time he has on each play. His arm is accurate and he doesn’t use it unless he has to. At the plate, he showed a good approach, staying inside the ball and working the other side of the field. On the mound at the end of the game, his fastball sat 87-89 with hard late run and plane from his high three-quarters arm slot. He showed a slider with 10/4 break at 69.

4.8.16:  Grammes is an athletic infielder that hits from the right side. He has a smooth load back to a wrap with decent hips and balance. He has quick hands and good bat speed, with a short path to the ball and good extension. He has gap power to all fields with home run power to his pull side. At short, he is smooth and throws from a three-quarters arm slot with a short, loose arm action. On the mound, he throws from a low three-quarters arm slot with a drop and drive delivery and a lightning fast arm that generates velocity with some effort. His fastball sat 87-89, with most of them being 89, with heavy run. He threw one 10/4 slider that ran 66.

2/15/19: A two-time high school state champion wrestler, Grammes is athletic and super strong at 6-foot-1, 200 pounds. He showed off his 70-grade raw power in batting practice, crushing balls deep into left field at Boshamer Stadium. During his first game at-bat, Grammes showed good place discipline, laying off several breaking balls out of the zone and working Luca Dalatri for a hard hit single to left field with two strikes. On the mound Grammes works from the far first base side of the rubber, delivering the ball from a three-quarters slot with effort. Ran his fastball up to 98, sitting mostly 97 in the first inning. Although not confirmed with TrackMan, his fastball spin rate looked average for the velocity he throws. Also mixed in a below average slider at 85-87 mph, showing fair feel for the pitch. During his 3.2 inning start, he allowed six runs on six hits while walking four and striking out two with scattered control throughout. The alignment in his delivery appeared improved from a previous look last summer in the Cape. Grammes is a prospect both on the mound and in the batter's box. The development of a consistent breaking pitch and improved fastball control are the keys to his draft value. Although smaller in stature, his two-way talent and tools remind me of Bobby Dalbec, a fourth round pick by the Boston Red Sox in 2016. (Seifert)

8/5/18: A two-time high school state champion wrestler, Grammes is highly athletic with excellent strength throughout his body. He showed the best velocity I saw in the Cape this summer. With a super quick arm from a three-quarters slot, Grammes sat 96-97 mph while touching 98 during a recent one-inning outing at Chatham. Lands cross-body and pigeon-toed with effort in his delivery. The unstable landing causes a recoil hop to his arm side during ball release. He’s trying to throw a pitch over home plate while his alignment is towards the on-deck circle of the third base dugout. This plays a major factor in his present command struggles and his ability to pitch. Not necessarily an easy fix to his delivery, it certainly looks to be correctable through instruction and repetitions. His present secondary stuff is limited to a flat 83-85 mph slider. Any improvement to his alignment and direction to the plate should also help the finish to his slider. No matter his current performance, or even his performance next spring on the bump, his athleticism and arm strength will be highly valued next June. There are just not too many live arms like his out there in amateur baseball. (Seifert)

8-5-2018: HITTER 6’2/200, athletic and strong from head to toe. Plus raw power to his pull-side and plus-plus arm strength. Solid infield actions. Ran a 4.32 and 4.33 from the right side to first base. Pull hitter with stiffness to swing. Some swing/miss tendencies. Although less polished, his two-way abilities with big right-handed power and arm strength remind me of current Boston Red Sox prospect Bobby Dalbec. (Seifert)
