Plus arm speed; above-average length to arm path, drops down out of hand break; doesn't use size as well as he could during leg raise/gather at top of delivery; inconsistent timing of arm and explosion towards plate, arm drags behind body at times.
Dunedin Blue Jays (High A, Blue Jays)
50, set-up man
Plus velocity stemming from size, easy action and live arm; below-average command causes it to play down at present; strong downward plane; minimal arm-side run, not enough to generate ground balls or miss bats.
Potential plus pitch, sharp two-direction movement; average present command with tendency to miss glove side; when commanded, will dominate left-handed hitters; has the potential to miss right-handed bats as well.
Well below-average pitch; thrown far too firmly, minimal movement, below-average command; very deliberate changes in delivery and arm speed, telegraphs pitch early in delivery; if he threw it for strikes more often, it would get hit very hard.
Labourt has an impressively live arm with the natural size and velocity that makes him an extremely attractive prospect. His flaws, however, will likely make him a reliever, though he could be very good one.
He's not a great athlete, which limits his ability to control his body and repeat his mechanics. That leads to major questions about whether or not he'll ever be able to have enough command to start. Additionally, his changeup is no where near where it needs to be in order to be a usable third major league offering.
On the plus side, however, his combination of fastball velocity and bat-missing slider could make him a high-leverage reliever. In order to pitch in the late innings, he'll have to continue to improve the command of his slider, which he can use to attack righties when he is able to keep it down in the zone. With that combination and some additional fastball command, he could be a high-leverage arm. If the command never gets to that level, he should still be a highly effective situational reliever who makes a career out of dominating left-handed hitters.
