Notes from the Field (4.6.18)

Physical Description: Strong pitcherís frame. Looks the part, doesnít have the size of a typical teenager. Durable frame and looks like someone who could one day throw 200 innings a year. Wide, mature body that looks all of his listed height and weight. Body will need maintenance and bears watching as he matures. How his body develops will depend on how much work he puts in off the field both in-season and during the offseason. Height is imposing on the mound.

Mechanics: Controlled, repeatable delivery. Loose arm. Throws from a three-quarters arm slot. Starts on the third base side of the rubber from the wind-up. Free and easy arm action. Starts with his feet close together and slightly pointed towards the on-deck circle on the first-base side. Utilizes a high leg lift and gets extension over his front side. Hides the ball briefly when he brings it behind his back and then again behind his head as he comes forward. At times has trouble getting his arm in sync with the rest of his delivery. When arm is out ahead, will miss up to the glove side; when arm drags behind, tends to miss arm-side.

Fastball: Sits 91-93 mph, but will pitch in the 94-96 mph range at times. Generates easy velocity. Pitch gets on hitters quick and has life. Needs to show the ability to hold velocity deeper into games. Has the potential to sit at higher velocity as he matures. Pitch has shown swing-and-miss potential, with arm-side run at times and cut on other occasions. Potential to develop into a plus-to-better offering.

Curveball: 79-82 mph. In at least one Spring Training look was up to as high as 85 mph, and in the past has been as low as 75 mph. 1-to-7 shape. At its best, shows depth and late finish. Has advanced feel for the offering and does a good job snapping the pitch off. Can throw it for strikes or bury it down and out of the zone when looking for a swinging strike. Has the potential to be a big league-quality out pitch. Already shows plus and has the potential to become a plus-plus offering with improved consistency.

Changeup: 84-86 mph. In the past sat 80-83 mph. Clear third offering at present. Didnít throw pitch much in high school and didnít throw much in outings scouted in 2016. Incorporated the pitch more in 2017, but pitch was a work in progress as he tried to develop feel for it. At times will show average-to-better potential with late fade. At other times, will show well-below-average, coming in straight and firm and looking like a fastball he took something off of. Doesnít throw with consistent arm speed; still developing. Solid-average potential, but will take some time to develop.

Career Notes: Was considered by some to be the top on-field talent in the 2016 draft class, but fell due to signability and makeup concerns. Committed to Vanderbilt initially. Conflicting reports about whether he decommitted the week of the draft to commit to Chipola (Fla.) Junior Collegeópotentially allowing him to re-enter draft in 2017óor whether Vanderbilt pulled his offer; SoxProspects sources unanimously confirmed the latter story. Transferred to IMG Academy in Florida for his junior HS season but returned to Barnegat High in New Jersey as a senior and was later retroactively suspended for an improper transfer, causing his team to forfeit two games. Signed for just under $500,000 over slot. Participated in 2016 Fall Instructional League. Club reportedly was unhappy with his conditioning entering 2017 Spring Training. Suffered an intercostal strain during his first start of the 2017 season (giving up 9 runs as he tried to pitch through it), causing him to miss two months. Was shut down in mid-August with forearm soreness. Father was arrested on drug and weapons charges during 2017 season. Worked out with Chris Sale in Ft. Myers during the 2017-18 offseason.

Summation: Has the potential to develop into one of the top left-handed pitching prospects in baseball. Projects as a solid number three starter. Has the ceiling of a high-end number two starter. Has the build of a workhorse starting pitcher and clean, repeatable mechanics to be able to sustain 200-plus innings a year. Early makings of a three-pitch mix with fastball and curveball both projecting to be at least plus offerings. Could stand to add a cutter to give hitters another look when he reaches the high minors. Has a wide range of outcomes with a significant gap between his floor and ceiling. Has great potential but has a long way to go developmentally.
