Starting rotation (5) - Freddy Peralta, DL Hall, Colin Rea, Wade Miley, Jakob Junis
It's already been declared that Freddy Peralta will start Opening Day, likely followed by DL Hall and Colin Rea for that first series of the season. With Hall making it and the other young pitching prospects all being reassigned to minors camp, the battle for the final rotation spots are down to a few veterans.
Wade Miley will be in the rotation if healthy. He's had a balky shoulder this spring but signs are pointing now to him being ready to go for that first week of the season, meaning he avoids an IL stint and will be on the rotster. The fifth spot appears likely to go to Jakob Junis, who could fill a variety of roles but appears primed to start in the rotation.
The other candidates in camp for a rotation spot to start the year are Joe Ross and Aaron Ashby, both of whom are coming off of missed seasons due to injury. Ross hasn't pitched in the majors the last two years and Ashby missed all of last year. One of them is likely to earn a bullpen spot as the swingman who can provide long relief.
It's hardly looking like the dominant group the Brewers had in their rotation a year ago, with a couple veteran innings eaters and a prospect trying to go from relieving to starting, but this is likely what the first turn through the rotation will look like.
