Vientos entered the spring as one of the more intriguing high school bats in the country, one who many thought had first-round potential. An up-and-down spring has made him a bit more of a polarizing prospect than that, with opinions on him varying greatly.

Vientos’ offensive potential is what had scouts interested in the first place, so if you saw him when he was swinging the bat well, you like him. He hasn’t done that as consistently as some would have liked to see. He does show good bat speed and has definite power potential from the right side of the plate. Vientos isn’t overly athletic, so even though he plays shortstop for his high school team at American Heritage, he will likely have to move to third at the next level, with some thinking he has the hands and arm strength to handle the hot corner.

Vientos did miss some time this spring with a quad injury, but he certainly has been seen enough over the summer and at events like the National High School Invitational. He reminds some of Manny Machado in terms of body type, and he’s also drawn a Michael Morse in high school comp. A team believing his bat will play will give the Miami commit a shot in the opening few rounds.

Baseball America

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.



At his best, Vientos demonstrates outstanding bat speed, 60-grade power, and the hitting feel to make that power work in games. His advocates see him as a player who will hit for both power and average. He also has a strong throwing arm and soft hands. He plays shortstop currently but some project a move to third base, where he could be a force along Manny Machado lines.

His youth is another attraction, as he has more potential development time available than most other players in the draft.


22. Mark Vientos, Shortstop, Flanagan HS (FL); Committed: Miami

Flanagan High School has shown a strong track record, seeing the likes of J.D. Martinez and Mike Napoli etching their name in Falcons history. The current team shows more promise than almost any other before, with Ray Evans’ group possessing multiple Division-I players, including hard-throwing southpaw, Jeremy Cook, and top draft prospect, Mark Vientos. Both will likely hear their name called in the draft, but Vientos seems destined to be one of the very first.

Though it will be hard to lure Vientos away from his commitment to the University of Miami, scouts are raving about his upside. He’s been on the radar since his early high school days for his impact a game in all aspects, giving him the potential for five above-average tools. However, there’s a lot to still see in his overall game, and there’s no larger critic to Vientos’ game than himself.

Everything with Vientos stems from his physical frame, at six-foot-four and 185 pounds with room to fill out. There’s a high load of strength in Vientos’ swing from the right-side, stemming from a wide stance, firm base, and plus bat speed. With a line-drive stroke, there’s promise of Vientos hitting for contact and power in the long run. The biggest knock will be his lack of approach and need for better pitch recognition, but with his aggressive nature, he’ll feed on fastballs prior to the draft. On the defensive side of the ball, Vientos has a good chance at staying at shortstop due to his quick movements, range to both sides, and plus arm. If Vientos is moved to third-base, which won’t happen until he reaches the upper minor league levels, he could be a premier defender. With added size, and maybe a sign of improving his average to above-average speed, organizations will be jumping to take one of the younger upside talents in this draft class.



Teddy- I LOVE THIS PICK!!! He was on my draft board, and is a power-hitting 3B. He will likely be in Kingsport or Gulf Coast League after signing. High high upside, boom or bust type.

Kevin- Love this pick! There is definitely some risk with him, but I think he has a ton of potential! I’m glad we got him where we did because taking him at #20 would’ve been scary. This is a nice project to have and I think working with Long, etc. will help him tremendously!

    I like this pick more than the first round pick. Liked the talent of Jaren Kendall more than a lefty that throws in the low nineties. However, putting a power hitting third baseman in the system is great, if they can sign him. I wonder is $1.1 is going to be enough.
