Mark Vientos

Even as an underclassman, Vientos was well-known for the huge upside in his bat. Before transferring to American Heritage, Vientos participated in the 2016 National High School Invitational with Pembroke Pines, Fla.'s Flanagan High where he showed rare ability to impact the baseball. On the summer showcase circuit the following summer, Vientos consistently hit the ball hard and that hasn't stopped this spring. At 6-foot-4 and 200 pounds, Vientos has a projectable body that should add even more strength. He has thunderous hands and he's able to generate explosive bat speed without loading his hands deeply. He's able to drive the ball with backspin to the gaps and he projects for at least plus power as he learns to loft the ball more. Defensively, Vientos is unlikely to stay at shortstop, lacking the glove actions or body control typically found at the position. He's also a well below-average runner. His plus arm strength leads scouts to project him moving to third base or a corner outfield spot.Vientos is one of the youngest prospects in the class and won't turn 18 until December. He is committed to Miami, but his loud offensive skillset and youth are likely to entice a team to pick him on the first day of the draft.
