Let’s start reviewing 2023 performance. We’ll start with hitter wOBA, comparing it to Statcast’s xwOBA. Why should we care how a hitter’s actual wOBA compared to his xwOBA?

I love identifying early starting pitcher velocity surgers, as increases in velocity, if maintained, often lead to breakouts, or at the very least, strikeout rate surges. But do these early season velocity increases last? Let’s review the increasers I discussed at the beginning of the season to find out how they performed over the rest of the season.
