Bleacher Report

Player: Keith Weisenberg

Drafted by: Toronto Blue Jays

Position: RHP

DOB: 12/6/1995 (Age: 18)

Height/Weight: 6'4", 185 pounds

Bats/Throws: R/R

School: Osceola (Florida) HS

College Commitment: Stanford



It's rare to find a 6'4" right-hander with a commitment to Stanford who will sneak up on you, but Keith Weisenberg is so unassuming with everything that he does, it's easy to dismiss him as an inferior talent to the top-tier pitchers in this class. 

You will be mistaken. Weisenberg doesn't have the big velocity that fellow Floridian pitcher Touki Toussaint does, but the overall package has looked more impressive in showcase events. He was a star at the World Wood Bat Association Championships last year, touching the mid-90s with his fastball and dazzling with his full-on arsenal of stuff. 

Unfortunately for MLB, Weisenberg is believed to be a tough sign away from his Stanford commitment, according to Kiley McDaniel of If teams believe that, he will fall into the later rounds to a team with no real chance of signing him but hoping to convince him that pro ball is the place for him. 


Full Scouting Report

Note: Numerical scores are on the conventional 80-point scouting scale, with the current score first and projected score second.



There's still a lot of projection left in Weisenberg's 6'4" frame; he's a lanky 185 pounds and has the frame to support more bulk as he gets older, which is only going to help his stuff and stamina; mechanics are clean for the most part, though he does have a tendency to fly open, which causes the ball to go sailing; arm works well, and the release point is consistent when he stays on line to the plate. 


Fastball: 55/65

Wesienberg's heater already has low-90s velocity with good running action, especially to his arm side; room to add some miles per hour to it, which will only make the late life play up and give him a real chance to have a plus-plus fastball in time; better throwing it inside to right-handers, but isn't afraid to attack lefties where the pitch tends to run back over the plate; tall frame gives excellent plane on the fastball, making the late life even more useful. 


Slider: 50/55

There seem to be two different versions of Weisenberg's slider; best one has sharp two to seven tilt and eats up the back foot of left-handed hitters, though the one that shows up more often doesn't have that same tilt down in the zone but is good enough to miss bats; does an excellent job of staying on the side of the ball to get the necessary movement on the breaking ball without telegraphing what's coming.


Changeup: 45/55

Weisenberg does show some feel for the changeup already, though it's not a sharp offering for him; straight pitch does come in a little too firm, leading to some hard contact when he's not able to place it low in the zone; good deception in his arm action, so it should at least play average in the future. 


Control: 45/55

With such clean mechanics and a good, repeatable arm slot, as well as tremendous athleticism, Weisenberg already does a exceptional job of pounding the strike zone; fastball and slider are present weapons, with the latter being thrown to all four quadrants on his best days; changeup is still coming along, keeping the control from being more than fringe-average at present. 


Command: 40/50

Problems come for Weisenberg when he gets too aggressive on the mound, trying to blow hitters away, making his hips shoot open, causing his arm to push the ball instead of guiding it into the box; doesn't have consistency with the changeup to project better than average control in the future, though the fastball works so well that he can get away with a show-me third pitch. 


MLB Player Comparison: Tommy Hanson

In addition to having power arms at the time they were drafted, Weisenberg and Tommy Hanson also have some similarities in their deliveries. Weisenberg hides the ball in a similar way that Hanson did at his best, then explodes forward with excellent drive and arm speed to generate velocity. The bottom fell out for Hanson quickly, though there's nothing to suggest Weisenberg is in for a similar fate. 


Projection: No. 3 starter in first-division rotation


MLB ETA: 2017


Chances of Signing: 60 percent

As mentioned before, Weisenberg's commitment to Stanford is going to be a huge obstacle which teams will have to decide whether they want to work around or not. It will also come down to what the player deserves he's worth, which, given the projection left, could be a significant amount that makes it more beneficial for him to pitch three years in college and return in 2017.
