Carlos Herrera, RHP
Carlos Herrera came to the Milwaukee Brewers in 2015 as part of the Adam Lind trade. Herrera has just turned 21 years old, and he’s rated as a top-30 prospect. He spent all of 2018 at Single-A.
Herrera threw 85 2/3 innings, and posted a 5.46 ERA with the Single-A Wisconsin Timber-Rattlers. He struck out 60, walked 48, and was tagged for five homers.
Herrera has a fastball that sits in the low-90s, and a solid breaking ball, but he lacks physical maturity, and needs to develop.
Of all the top-30 prospects that the Milwaukee Brewers have to add to the 40-man roster, Herrera is the most likely to get exposed to the Rule V draft. He hasn’t reached High-A, and has a lot of work to do before he’s ready for the Majors.
Teams have to carry a Rule V Draft selection for the entire 2019 season to retain their rights. Carrying a pitcher as limited as Herrera for a full season would be a tough ask of a Major League roster. He’ll probably remain off the Milwaukee Brewers 40-man roster, but it’s unlikely that he’s selected given his limited experience, and slight frame.
