Wily Peralta is having a good spring so far posting 7.4 K/9, a 1.09 WHIP, and a 1.23 ERA in 7.1 innings. His opponent quality (OppQual) is 8.5, so he’s thrown against some good competition. He got his first save of the spring against the Chicago Cubs last night allowing one hit that plated an inherited runner and one walkout with no strikeouts. The most disconcerting for Peralta this spring is the high walk rate - four walks to just six strikeouts. Are we in for another spotty season for the Royals (potential) closer for 2019?
Since it is inopportune at this point to make weighty assessments on how Peralta will attack hitters this season, we can take a look at what issues arose in 2018 and see if Peralta is able to correct them going forward.
