10. OF Kevin Alcantara
The main prize of the Anthony Rizzo trade in 2021 was outfielder Kevin Alcantara, who stands at a commanding 6'6 and wields some of the best raw power in the system. The 20-year-old currently plays for the South Bend Cubs, where he is slashing .219/.255/.356 with 3 home runs and 21 RBIs. Those numbers don't exactly jump off the page, but the potential is there for Alcantara to be a 30-home run threat if he can fill out his tall frame. As the No. 3 prospect for the Cubs, Alcantara could end up being a solid trade chip since the outfield is pretty much set for the next few years.
