It’s a bit of a surprise to see the Milwaukee org giving up on a player who was once considered a potential mid-rotation starter. Diplan has never been an elite prospect, but has certainly been on the prospect map for quite some time.
Unfortunately, despite holding a 40-man spot since the fall of 2017, Diplan has yet to earn his way past the Double-A level. He returned there to begin the present season, but continued to struggle. In 114 2/3 total frames at the penultimate level of the minors, Diplan carries a 4.79 ERA with 9.4 K/9 and 5.7 BB/9.
It bears noting that the Brewers could still utilize Diplan in a trade. He can be shipped out to another organization before the trade deadline. Otherwise, he could be a possible waiver claim target for a team that likes his long-term outlook.
