Brock
Arnold

6/5/18 - Young 6-foot-1, 165-pound frame. Two-way prospect. Body projects to add considerable size and strength in the coming years. On the mound Arnold creates downhill angle to the plate. Long, clean, hand driven arm action. Lower and upper half separate well. Lead leg fully stabilizes into ball release resulting in good transfer of energy. Worked 73-76 mph with his fastball using a high ¾ arm slot. Have seen up to 78 mph in the past. Two-seam showed fade to his arm side. Had feel for his curveball thrown at 62-64 mph with solid 11/5 shape. Repeated fastball arm speed and mechanics on his 68-72 mph changeup. Offensively started from a tall, open, balanced stance. Leg kick loading pattern and stride. Back elbow remained high into stride foot contact. Consistently hit balls hard in the air as his swing generates plenty of loft. Showed present bat speed and projects for more as he matures; 81 mph exit velocity. Defensively profiles well at first base. Showed the ability to move well around the bag; 76 mph position velocity. 7.67 60 yard dash.

11/12/17 - Lean 6-foot, 160-pound frame with plenty of room to add strength as he matures. Two-way prospect is a strong follow as LHP and 1B and one of the top prospects at the event regardless of class. On the mound Arnold works with a compact delivery, explosive lower half and generates plenty of arm speed from a high ¾ slot. Fastball sat 75-77, T78 flashing good downhill plane. There’s plenty more velo to come as he adds mass and strength to his frame. Sweeping 2-8 breaking ball showed consistent rotation at 63-66. Showed advanced feel for fading changeup with good arm speed at 71-73. At the plate, hits from tall, open setup with leg-kick trigger. Creates very little separation, using only a small negative move with his hands. Shows solid bat speed and makes an aggressive move with his lower half as he looks to lift the ball with a high two-hand finish. 79 mph exit velocity will increase rapidly with physical maturation. Defensively, his athleticism currently profiles best to 1B where he moves well and registered 76 mph infield velocity. Also worked out in outfield where he threw 78 mph. 7.58 60-yard dash with good running form. Has a chance to become a high-level prospect with significant increase in physical strength.
