Physical presence with a broad shoulder and a strong, mature lower half, listed at 6-foot-3, 230 pounds. In control and has feel for his delivery, working in rhythm, and is a quality mover at his size. Reliever profile, but shows a solid three-pitch mix with the fastball working up to 96 mph over the weekend. Two appearances, working one inning on Friday and four on Sunday, his longest outing of the year, coming off a redshirt season in 2023 due to an injury. Fastball at 94-96 on Friday and 92-95 on Sunday. Has the ability to work both sides of the plate, worked in the bottom of the zone throughout the outings. Slider sat at 81-85, spinning up to 2600rpm, with hard horizontal break, running away from right-handed barrels with feel to land the slider and working to the glove side to expand. Threw several change-ups vs left-handed hitters on Sunday, straight with deception in the arm speed at 85-88. Thrived in high-leverage situations and is a high-level competitor that pitches with emotion. Another 49er arm that is set to move quickly through a minor league system, which is a must at the age of 24.

At 23 years of age, Rossi is an experienced bullpen arm for the 49ers with “now” stuff. He will sit 95-96 mph with his fastball, while also showing an above-average 84-86 slider and an effective split-change, 86-88. So far this spring he has yet to allow an earned run and surrendered just two hits in 8.2 innings with 14 strikeouts. The righthander combines stuff and the ability to pitcher that is needed for success as a short reliever at the professional level. In that role he could be a quick mover through a minor league system.

Rossi has consistent sinking action on the FB with ability to throw off speed successfully, wipeout slider up to 85 mph.
5/27/17- Roughly 6-foot-1 195-pounds, he has a strong lower half. Lands in line with a clean high 3/4 arm action. The arm has some twitch and is fairly quick currently. He does not quite get down the mound or get extended very well, but still worked 84-86 mph with the fastball that had heavy life. The arm work and as he learns to get extended should make a jump. Showed a feel for a curveball at 70-72 mph with quality shape that looks like he could turn into a harder slider. Attacked the hitters, very interesting follow.
