9. Los Angeles Angels -- Jose Alberto Rivera, RHP (Astros)
Scouting Report: The Astros signed Rivera signed for $10,000 at 19—relatively older for a Latin American signing—so he didn't make his full-season debut until he was 22 in 2019. He has electric arm speed, producing a fastball that ranges from 97-102 mph with lively tailing action. He throws a split-change in the mid-80s, a pitch that progressed throughout the 2019 season to flash above-average by the end of that year. He has a hard slider in the mid-80s as well, but it's not reliable in terms of the pure quality of the pitch or his ability to hit his target. He has an aggressive, high-energy delivery that he will need to corral to repeat more often and improve his strike-throwing ability. His control will probably lead to issues in 2021, but he should be able to stick around the Angels' bullpen as a power reliever.
