Physical Description: Long, athletic build; slight taper with long arms; high and trim waist with long legs and big feet. Still room to add modest strength throughout. Undisclosed injury in 2021 has prevented a season debut. Overall frame reminds me of Clay Buchholz.

Mechanics: High 3/4 slot with moderate effort; goes high effort when he needs extra. Busy windup with good pace. Tall and fall motion with clawing arm action. Modest downhill plane. High glovework, coiled leg kick, and plus arm speed yield above-average deception. Impressive repeatability considering all the moving parts.

Fastball: 91-93 t95 with tailing action; flashes riding life when thrown in the upper third. Shows advanced control; works all four quadrants to toy with hitters. Some velocity projection remains with added physical strength. Still some gap between what is and what could be, but added velocity with his command of the offering warrants an above-average grade long-term. Grade: 55

Slider: 78-83; manipulates the offering with slurvy action in the lower velocity band; more traditional slider bite 81-83. Fills the zone and also uses it for chase. Casts occasionally, floating it in arm side. Can improve with continued reps and pro instruction; making it a solid-average offering at the highest levels. Grade: 50

Changeup: Fringy offering 83-85; flashes above-average but currently sits below average. Shows fade arm side but more often lacks the drop necessary to miss bats; struggles to locate glove side. Maintains arm speed and fluidity. Likely develops as a usable offering long-term, not a swing-and-miss weapon. Grade: 45

Control and Command: Above-average control with average command. Consistently fills the zone, especially with the fastball. Stellar walk numbers in his brief pro career. Fastball command is at projection--improvements will come from continued development of the offspeed. Heavy fastball usage that may need to back off at the highest levels. Control: 55 | Command: 50

Overall: Between the pandemic and a mysterious injury, Rays fanatics are eagerly waiting on Goss to show his abilities beyond his 17 innings of rookie ball in 2019. This is one of the more intriguing arms in the system to me, with a ceiling of a mid-rotation starter within the realm of possibility. There is relief risk, depending on both his health as well as the development of his changeup. In a bullpen role, his fastball/slider combination would likely play up in both velocity and crispness and his runner's pace on the mound would keep hitters on their heels. Still, with strong control attributes, he'll get every chance to start and has more upside (and risk) than many of the other arms in the organization.
