When I first saw this trade I thought the Rays had hired Bill Smith to do their trading. Looks like a really good trade right now from the Brewers perspective. J.P. Feyereisen (whom no one can spell or pronounce) is a 16th round draft pick out of River Falls, WI with a solid minor league track record. Drew Rasmussen was actually drafted by the Rays in the 1st round in 2017 but didn't sign after he got hurt, then was drafted by the Brewers in the 6th round the next year.
I think the interest for the Rays here is Rasmussen and they must feel he has real upside, Also, they have viable shortstop prospects to move up. Adames is a major league shortstop that will help the Brewers who have struggled from the shortstop position.
If Rasmussen develops into a solid major league starter give kudos to the Rays for their savvy talent evaluation and courage to pull off what looks like a risky trade. If Adames hits and gives the Brew Crew some solid shortstop years, they'll be happy.
