Underclass Games (September 24th, 2017)
Rumsey has a lean, athletic build at at 5-foot-11 165-pounds with long, wiry limbs. Ran the 60 yard dash in 7.50 seconds and recorded an exit velocity of 86 MPH. At the plate, Rumsey starts in a tall stance with hands above back shoulder and feet situated in a neutral position. As pitch comes in, Rumsey uses a leg kick and stride to start swing as hands load straight back with some fluidity. Slight hitch in load process – stiff front leg as hips turn with some fluidness to the ball. Uphill swing, finishes balanced. Defensively – took reps at 3B. Throws topped at 70 MPH across the infield with some backspin and carry. High-3/4 slot with throws, still growing into frame with his footwork. Pitching – fastball topped at 82 MPH and sat mostly 78-80. Flashed a curveball with smaller, tighter 11/5 break at 66-68 MPH. Long, loose arm action from a high-3/4 slot. Creates some downhill leverage with extension over landing leg. Definitely a prospect to keep an eye on.
