The NLCS series surges to 7.4 million viewers in the decisive Game 5 victory over the Los Angeles Dodgers.

The Los Angeles Dodgers may be down for the count this post-season — but if Major League Baseball's postseason maintains its current ratings momentum, Fox may be looking forward to an especially strong World Series this October.

Thursday's Game 5 win for the New York Mets, which secured their spot in the NLCS Championship, averaged 7.4 million viewers on TBS. That's up 21 percent from the last NLCS Game 5 in 2013 and keeping in line with the significant growth this MLB postseason has seen.

While all MLB coverage is up this season, TBS has been doing particularly well. Through Tuesday, it's been the most-viewed MLB coverage to date — up a bonkers 47 percent from 2014 with an average 5.7 million viewers per game. Coverage is up even more among adults 18-49, surging 53 percent. According to the MLB, overall consumption is up 22 percent across networks and platforms.

The Dodgers-Mets series had a slower start than some of the other series, thanks in large part to the New York market showing up in bigger droves than fans in L.A., but Wednesday and Thursday saw both cities' showings climb.

Here's the full breakdown:
Game 1: 4.7 million viewers
Game 2: 4.2 million viewers
Game 3: 3.96 million viewers
Game 4: 6.3 million viewers
Game 5: 7.4 million viewers

The MLB post-season is also proving to be a particularly good investment for Fox Sports 1. Little more than two years into the cable network's launch, it's clocking record ratings thanks to the American League Division Series. Wednesday's decisive Game 5 between the Houston Astros and the Kansas City Royals reached nearly 6 million viewers on FS1. That's almost 1 million north of the previous record set by a NLDS game in 2014. (Overall, the ALDS was actually off 10 percent from the comparable NLDS games last year — when the series ran just three games.)

Up north, the Toronto Blue Jays' strong performance is prompting records of its own. Canadian cabler Sportsnet hit a record audience on Wednesday with 4.9 million viewers tuning in to the Jays' win over the Texas Rangers.

Baseball gets some broadcast exposure, effective Friday, with Game 1 of the American League Championship Series airing on Big Fox.
