Howie Kendrick's three-run home run in Game 3 of the NLDS between the Los Angeles Dodgers and New York Mets was the final long ball.
The Chicago Cubs hit a playoff-record six home runs in their victory over the St. Louis Cardinals.
The 61 total runs scored Monday also set a postseason record.

The previous record for runs was 48, set Oct. 5, 2002.
