Marco is a versatile player that can play in the middle infield and pitch. At shortstop, Marco has good pre-pitch movement, presents his glove, and takes good angles on grounders to read the hops. Sticking his nose into grounders will help him not stab at balls, which he does at times. Also, improving his body control on slow rollers and not being narrow with his feet should help defensive grades. At the plate, Marco stays inside the baseball with his quick hands, displaying a middle-of-the-field approach. Relaxing at the plate will help loosen his grip and stiff back elbow, improving hitting grades. On the mound Marco is a competitor, don't tell him he's 5'9 because he's coming after you as a hitter. He has excellent leg drive and attacks the zone. He also fields his position extremely well due in part to his infield abilities. His fastball ranges from 78-83 mph on a slight downward plane. His curveball displays 10-4 shape and induces a lot of grounders. Marco also shows great feel for his change-up that fades at the plate. Having some glove side pull on his fastball and engaging his hips in his motion should help increase pitching grades and velocity. Overall, Marco is an athletic two-way player that will impress coaches at the next level.
