2022 National Rankings (in season)

Miguel Bleis, OF, Red Sox
Bleis, whom Boston signed for $1.5 million in January 2021, already checks in as the Red Sox’s No. 18 prospect. He showed well in the DSL in his pro debut last summer and already boasts electric bat speed and bat-to-ball skills at the front of a tantalizing tool set. He’s a smooth route-runner in the outfield, too, and should have the chops to stick in center field.

17. Denis Reguillo, RHP, Red Sox: Reguillo is starting to flirt with low-90s velocity after throwing mostly in the mid-to-upper 80s before signing out of the Dominican Republic. He has the physical projection to throw harder, which if it comes on would enhance his stock as a pitcher who already has a good delivery, fluid arm action and advanced pitchability for his age.

Chief among the unexpected additions to the Top 100 is Red Sox righty Brayan Bello. I’ve long considered Bello to be a relief prospect due to the length of his arm action, but he’s never generated excessive or role-altering walk rates, and when you look at the clusters of his pitch locations, it’s clear this guy has feel for locating his stuff even though his delivery features a good bit of violence and effort. He has three impact pitches – a mid-to-upper-90s sinking/tailing fastball, a plus slider, and a plus changeup – and is on the doorstep of the big leagues, and I’m buying that he has the command to start. Bello is very similar in many ways to Brewers lefty Aaron Ashby (sinker-oriented fastball, plus secondary stuff, arguable relief risk), and so he enters the list in that zip code.
