With the addition recently of both the Live and Yesterday splits to the site’s leaderboards, it’s possible now to get a sense of how players are performing in real time by certain advanced metrics in a way that wasn’t before.
What the author has found himself wondering, though, is how best to adjudge the day’s Champions of Hitting and Pitching using the metrics available at the site. As is the case even with larger samples, there are actually multiple ways of doing so — it’s a matter always, as Dave Cameron suggests, of the particular question one is attempting to answer.
Below are four metrics, all of which answer slightly different questions about a player’s single-game batting performance. I’ll looking at some pitching metrics tomorrow.
wOBA
Weighted On-Base Average, or wOBA, is a record of a hitter’s batting production for the day scaled to on-base percentage. As such, it’s the best way to determine offensive output per plate appearance. That’s its strength. It’s less useful for reporting cumulative production, however. So, a batter with one home run in a single plate appearance will have a higher single-game wOBA than another hitter who’s hit three home runs in four plate appearances — even though we might say that the latter has been “more productive.”
