A couple of weeks ago, our Drew Bonifant defied the haters and predicted Orioles reliever Miguel Castro would have a bounce-back 2020 after finishing the 2019 season with a disappointing 1-3 record and a 4.66 ERA. As Drew ably demonstrated, Castro’s ERA and win/loss record gave a false impression about a season in which pretty much all of his other indicators improved: batting average against, WHIP, walk rate, and most gaudily, strikeout rate (from 5.2 in 2017 to 5.9 in 2018 to 8.7 in 2019, a huge jump).
In fact, besides ERA, Castro’s only major indicator that worsened was home runs against.
