Major League Baseball鈥檚 goes into its dream matchup with its most-watched League Championship Series in seven years.

According to Nielsen, the two series averaged 5.35 million viewers on Fox, FS1 and TBS, its highest numbers since 2017.

According to MLB, Game 1 of the NLCS on Oct. 13 between the New York Mets and Los Angeles Dodgers averaged 20.6 million viewers combined in the United States and Japan.
