10 Rockies Prospects To Watch Beyond The Top 30

The Rockies Top 30 prospects rankings are up now for Baseball America subscribers, with full scouting reports, BA grades and tools grade projections for all 30 players.

Through the process of narrowing the list down to a Top 30, there are other intriguing names who didn’t make the cut but are worth monitoring, with the potential to jump into the Top 30 in the future. Some of those are players who might be in the upper levels and could see big league time this year, though likely in a limited role, while others are lower-level players still in the complex leagues with more upside but plenty of risk.

Beyond the Top 30, these are 10 prospects to watch in Colorado’s farm system.

McCade Brown, RHP. Drafted out of Indiana in the third round of the 2021 draft, Brown was unlucky in 2022, dealing with an unusually high batting average on balls in play. He flashes strikeout stuff with command, pairing a high-ride mid-90s fastball with a tight mid-80s slider, an upper-70s curveball with two-plane break and an upper-80s changeup. 

Riley Pint, RHP. The No. 4 overall pick in the 2016 draft took a roundabout route to the Rockies 40-man roster this offseason. While Pint possesses elite stuff with his mid-to-upper-90s fastball with an easy plus slider, he struggles to command the ball. It’s improved over the years, but Pint will still lose his release point consistently. He’s an upper-minors relief prospect who could contribute for the Rockies in 2023. 

Brayan Castillo, RHP. Castillo possesses some of the loudest stuff in the Rockies system. Castillo debuted in full-season ball in 2022, but struggled with command. He primarily uses a two-seam fastball and a slider, mixing in a four-seamer and a changeup. His two-seamer sits 94-95 mph and touches 98 mph at peak. His primary secondary is a hard cutter-like slider in the upper 80s that generated whiffs at a rate of 45% in 2022. 

Angel Jimenez, RHP. A projectable righthander with a three-pitch mix who debuted in the Dominican Summer League in 2022, Jimenez mixes a high-ride low-90s fastball with an above-average changeup and a sweepy curveball. He’s a name to keep an eye on in 2023. 

Blair Calvo, RHP. Added to the Rockies 40-man roster in 2022, Calvo possesses arguably the best breaking ball in the Rockies system—an upper-80s sweeper with over 10 inches of horizontal break on average. Calvo’s slider has an unusual combination of velocity and movement, rare for a slider of that style. He pairs that with a mid-90s four-seamer that sits 94-96 mph and touches 97 mph at peak. 

Bryan Perez, RHP. The nephew of former MLB starter Edinson Volquez, Perez is a projectable righthander with a three-pitch mix. Perez’s fastball sat 93-95 mph, touching 98 mph at peak during Arizona Complex League play in 2022. His primary secondary is a mid-80s changeup that generated whiffs at a rate above 35% last season. Perez also mixes in a mid-80s gyro slider he struggles to command. 

Sam Weatherly, LHP. Weatherly is a funky lefthander who’s dealt with shoulder injuries in recent seasons. When Weatherly is healthy he pairs a low-to-mid-90s fastball with an above-average slider. 

Ryan Rolison, LHP. A former first-round pick out of Ole Miss, Rolison missed all of 2022 with a shoulder injury. He had shoulder surgery in June of 2022, and reports convey that Rolison is fully recovered. Rolison could debut in the major leagues in 2023.

Ronaiker Palma, C. Palma is a standout defensive catcher who formed a formidable tandem with Drew Romo in 2022 for High-A Spokane. At the plate Palma is a high-contact hitter, making contact nearly 90% of the time in 2022, while rarely missing in the zone. It’s an aggressive profile with below-average power, but his defensive skills and high-end contact could earn him opportunities in the future. 

Case Williams, RHP. Williams is on his second stint in the Rockies organization after he was reacquired from the Reds in a trade for Mychal Givens. Williams uses four pitches, but his primary weapon is an upper-70s curveball with heavy two-plane break.
