For a team whose season will be defined by failures with runners in scoring position, the Yankees sure did seem to have a lot of enormous hits along the way. Especially late in the season too — September and October featured all sorts of memorable hits that injected new life into a team that was fighting tooth and nail for the division title down the stretch.
With some help from win probability added, or WPA, we’re going to take a look at New York’s five biggest hits of this season. If you’re not familiar with WPA, I highly recommend Joe’s primer. Long story short, it tells you how much an event — a hit, strikeout, walk, error, anything in baseball — increases or decreases a team’s chances of winning using historical data. For example, if the Yankees have a 50% chance of winning when I step to the plate and hit a walk-off homer (thus giving them a 100% chance of winning), I get credit for the +50% (0r +0.50 WPA) while the pitcher gets charged with +50% (-0.50 WPA). Simple enough, right?
Anyway, WPA isn’t a predictive stat and it doesn’t have a ton of analytical value. It lacks context like the quality of the pitcher and hitter, the impact of the game in the standings, stuff like that. It is useful for this kind of exercise though, a fun look back at some of the biggest hits of the season. You won’t be surprised to see that one player is featured prominently in this post.
