There were a lot of big hits this year for the Washington Nationals and there were a lot of big wins. This list is sorted by WPA which is Win Probability Added. It means that Jayson Werth‘s walk-off homerun in Game Four of the NLDS is not in the Top 10 because it was a tie game in the bottom of the inning meaning the swing of WPA was not big enough. This list is for games where Washington went from a low chance of winning to a high chance.
Next up is Number 5.
Danny Espinosa: July 20 vs Atlanta
The situation: 10-9 Atlanta, Bottom 9, Bases Empty
Pitcher: Craig Kimbrel
The result: +0.47
The Nationals were down to their final inning, against one of the best closers in baseball and then Espinosa hit this home run to force extra innings. The Braves scored in the 11th inning to put the game away for good, after coming back from a 6-0 deficit early in the game. One of the rare occurrences when a big swing in WPA does not end up in a winning effort.
