If Wisconsinite Connor Prielipp is still there, do they take a chance on him? Does his injury history push him down to the Brewers? Pipeline has him at #24.
The Brewers like up-the-middle guys so you can't rule out Zach Neto or Frelick-clone Drew Gilbert. Speaking of clones, there's Ethan Small clone Cooper Hjerpe, who in 84 IP this season has given up 57 hits, walked 17 (1.8/9 IP, and has improved every year), and struck out 135 (14.5/9 IP) against Pac-12 competition.
If I'm handicapping it, I'm ranking them in order as Campbell, Hjerpe, Gilbert, then Neto with Prielipp as my "if he's still available". If I have a "don't be surprised by" guy, it would be Hjerpe's teammate Jacob Melton.
