For those who follow me on Twitter, I talked a lot about cWPA during this year’s postseason. I pretty much shoved it down everyone’s throats and most people didn’t really understand what it exactly was.
According to The Baseball Gauge, “Championship Win Probability Added (cWPA) takes individual game win probability added (WPA) and increases the scope from winning a game to winning the World Series.” WPA percentage points take into account just a specific game’s moment’s impact on the potential final result, whereas cWPA percentage points take into account the effect of a certain play on a team’s chances to win a World Series that season.
