You know the story: Aaron Judge was in a mighty slump after the All Star Break. He batted .179/.341/.352 through August 27th, when Joe Girardi made the decision to rest him for two games. Since August 27th, Judge has recovered hit a pretty incredible .250/.413/.667. He's hitting 115+ mph home runs again, and making a push for AL MVP.
Here's what the season looks like using a rolling 10-game moving average of Statcast's xwOBA statistic:
1) Judge began to come out of the slump long before he was rested in late-August. He was legitimately terrible after the All Star Break in July. His xwOBA began to improve in early August, but has take off like a rocket since he was rested. However, it did clearly affect his strikeout rate:
2) Even when he was slumping terribly, Judge never really bottomed out to below-average for any lengthy period of time. His ability to take walks sets a high floor.
3) When Judge gets hot, he stays hot. Hit like a modern day Babe Ruth for two separate month-long hot streaks. He's hot now (September 10th and 14th were two of Judge's best three games of the season by xwOBA).
