As MLBTR’s Steve Adams noted earlier this week, Peralta was signed to a fully-guaranteed MLB deal. As such, the Royals will be on the hook for his entire salary unless he lands elsewhere, in which case his new team will pay him the prorated portion of the league minimum salary. Peralta allowed 14 earned runs across just eight innings during spring training. His 2017 campaign with the Brewers wasn’t much better, as the righty posted a cataclysmic 7.85 ERA across 18 appearances (nine starts) with the Brewers. The 28-year-old saw his walk rate skyrocket to a career-high 5.02 BB/9, while his HR/9 ended the year at a 1.57 figure.
Poor recent performance aside, Peralta’s designation was likely affected in part by Kansas City’s desire to hold Rule 5 picks Burch Smith and Brad Keller on the roster. The team is in a bit of a rebuilding period, so the upside of keeping these two young players for the long term probably outweighs the value of holding onto the struggling Peralta.
