Luis Ysla

Born: 04/27/1992 (Age: 22)
Bats: Left Throws: Left
Height: 6' 1" Weight: 185
Mechanics
Filled, medium frame with mass in midsection; violent drop-and-drive mechanics; very quick and short arm action; arm gets up early; low three-quarter slot; big head jerk; spins off toward third base with a big arm recoil; extension out front is limited due to fairly staunch front leg and aforementioned spin off; overall balance and posture in delivery is poor; lapses into flying open and will miss high and to the arm side; pitcher's release point tends to waver due to mechanical inconsistencies from pitch to pitch, negatively affecting control; places a ton of stress on the arm; delivery requires pristine athleticism to repeat, but the pitcher does not have the requisite coordination to replicate it consistently.

Pitch Type Present Grade Future Grade Sitting Velocity Peak Velocity Report
Fastball 50 60 92-94 96 Velocity: plus; sat 92-94 most of the night, touching 96 on a couple of occasions; held velocity throughout start. Command: below-average; delivery and arm slot inconsistency limits pitcher's ability to spot the pitch consistently; lapses into overthrowing and misses high and to the arm-side with regularity; limited projection due to max-effort mechanics, but additional repetitions should help in this regard. Movement: plus arm-side run with some late sink; shows explosive life on the hands of left-handed hitters; flattens out up in the zone; displays minimal plane due to lower slot and drop-and-drive mechanics. Comments: pitches aggressively with the fastball and attacks hitters with the pitch; elevates pitch to get whiffs when ahead in the count; will rely on sheer velocity at the expense of location on occasion, leaving the pitch over the heart of the plate for hitters to feast upon; velocity will play at the higher registers of this range out of the bullpen.
Slider 45 60 77-83 85 Command: fringe-average; shows the ability drop the pitch in as an early strike in the lower registers; sharper break in the mid-80s that was a swing-and-miss offering when located in the lower quadrants of the zone; lost command of the pitch the second time through the order, slipping under the ball with and causing it to float high in the zone. Movement: hard, late break with good tilt and two-plane break in the mid-80s; softer break in the upper-70s that is used in the zone as a freeze pitch; break on pitch varied between 1-to-7 and 2-to-8, depending on release point. Comments: will occasionally telegraph the pitch by slowing his arm and his mechanics; overall lack of control with the pitch makes it a fringe-average offering presently but flashes legitimate swing-and-miss potential with further refinement and repetitions; plays well off of the fastball.
Changeup 30 35 83-85 87 Command: poor; trouble locating pitch; missed high and to the arm-side and left the pitch high and hanging; Movement: displayed some arm-side run; Comments: threw only a handful of changeups in this appearance and struggled to locate the pitch; do not see the pitch becoming more than a below-average offering at the major-league level due to arm-slot inconsistency and lack of feel for the pitch.
Overall

In this look, the lack of a playable changeup and the strenuous mechanics leave limited projection for a role in the rotation. Due to the potent fastball-slider combination, Ysla has the ceiling of a high-leverage reliever, potentially in a setup role. Realistically, however, the command issues could force him into a middle-relief role, where he could be especially effective versus same-handed batters.

Ysla is 22 years old and is only in his second professional season, but the stuff is such that he could be put on the fast-track out of the bullpen in the Giants' system. He is currently seeing success out of the rotation due to his ability to overpower Low-A hitters with his arsenal and the funk that accompanies it, so it is hard to justify a move to the bullpen immediately. I'm not a believer in the rotation being his permanent home, however, and a move to the bullpen could get him to San Francisco as early as 2016.
