Feyereisen and Drew Rasmussen were traded from the Brewers to the Rays on Friday in exchange for Willy Adames and Trevor Richards, Robert Murray of FanSided.com reports.
The Rays have a well-earned reputation for getting the most out of previously unheralded pitchers, so it's possible they see something in Feyereisen, but the 28-year-old hasn't shown much in 28.2 career major-league innings despite posting a 94:31 K:BB through 61.1 IP at Triple-A in 2019. His 4.08 ERA in the bigs is decent enough, but comes with a 5.32 FIP and 5.02 xFIP, as he's combined a merely average 23.7 percent strikeout rate with a poor 14.0 percent walk rate.
