Besides the three Cubs kids, Starlin Castro, Anthony Rizzo and Dexter Fowler joined in the fun with solo shots. This was the Cubs' first postseason win at Wrigley Field since Game 2 of the 2003 NL Championship Series against the Marlins.
How important is winning Game 3? The team that takes a 2-1 lead in the NLDS has gone on to win 20 out of 24 series. The four teams that lost despite a 2-1 lead were the 2013 Pirates, 2012 Reds, 2011 Phillies and 2002 Braves, and the Cardinals were responsible for two of those instances, rallying to beat the Pirates and the Phillies in those series.
