Right-hander Trey Supak and infielder Ronny Rodriguez both cleared waivers after being designated for assignment by the Brewers earlier in the week, per a team announcement. They’ve been assigned outright to Triple-A San Antonio. Because they were outrighted to Triple-A rather than to the alternate training site, neither will remain in the club’s 60-man player pool. They’re both still controlled by the Brewers beyond 2020, however, even though they’re no longer on the 40-man roster.
The 24-year-old Supak spent most of the 2019 campaign in Double-A, where he notched a terrific 2.20 ERA ball with 6.9 K/9, 1.7 BB/9, 0.44 HR/9 and a 44.8 percent grounder rate over the life of 122 2/3 innings. That performance came in a pitcher-friendly environment and wasn’t fully backed by fielding-independent metrics (3.14 FIP, 3.59 xFIP), but it was a promising showing overall. He was hit much harder in a brief stint at the Triple-A level, but Supak has yet to have much experience at that stage of the minors.
The Brewers are likely pleased that the righty went unclaimed, as he’s long been ranked as one of the better arms in a thin minor league system. Clearly, the team now feels that others within the system have surpassed him, but they’ll now be able to continue to work on his development in future seasons. Supak has a minor league option remaining beyond the current season, but that wasn’t enough for another club to place a claim at this point, apparently.
Rodriguez never got into a game with the Brewers after coming over from the Tigers via waivers this winter. The 28-year-old is a versatile utility piece with a bit of pop but overwhelming on-base issues, as can be seen in his career .221/.254/.396 batting line. Rodriguez did swat 14 big flies in 294 MLB plate appearances last year, but those on-base woes clearly limit his value.
