New Features: More Stats & Integration

Quite a few feature additions just went into production.

-First off, WPA is no longer expressed as a percentage. Every player still has the same value, it’s just 100 times less.

-WPA is now displayed in each player’s game log and all the dates in the game logs are linked back to the correct Win Probability graph.

-There’s a new table for both batters and pitchers in the player stat pages that include the following Win Probability & Leverage stats:

WPA: Win Probability Added.
-WPA: The total of a player’s negative contributions towards their team’s win/loss.
+WPA: The total of a player’s positive contributions towards their team’s win/loss.
pLI: Average Leverage on a plate-appearance basis.
inLI: Average Leverage when a pitcher starts an inning.
gmLI: Average Leverage when a pitcher enters the game.
exLI: Average Leverage when a pitcher exits the game (game ends not included).
Pulls: Number of times a pitcher has been pulled from a game before it ended.
G: The number of games pitched in.
phLI: Average Leverage when pinch-hitting.
PH: Pinch-hitting opportunities.
OBP Wins: Player’s wins in a context-neutral environment.
Clutchiness: Difference between WPA and a Leverage adjusted OBP Wins.

For more information about these stats, take a look at the following links:
