With the Chicago Cubs’ 5-2 loss to the New York Mets on the night before Back To The Future Day, it looks like the Cubs are truly running out of time and options with the Mets now leading the National League Championship Series 3-0 and Game 4 tonight. For TBS, though, the matchup between teams in the top and third U.S. TV markets has already proven a winner, with Monday’s game getting a 7.0/12 metered market rating.

That’s up a home-run 49% from Game 2 of the NLCS on October 18 when the baseball playoff faced off against NBC’s Sunday Night Football, a full slate of primetime programming, and Week 2 of the sixth season of The Walking Dead. Last night’s Mets-Cubs is also the best any MLB postseason pre-World Series game has done since Game 5 of the 2011 American League Championship Series between the Detroit Tigers and those New York Yankees.

Compared to last year’s Fox Sports 1 broadcast of NLCS Game 3 between the St. Louis Cardinals and San Francisco Giants, last night grew 233%. A little bit more apples-to-apples: last night’s Mets win was up 75% in MM results from Game 3 of the 2014 ALCS between the Kansas City Royals and Baltimore Orioles drew. That game, won by the Royals, was shown on TBS on October 15, also a Monday.

TBS looked poised to win the night but we won’t know for sure until final numbers are in for what has been a surging series for the network so far. However, the big metered-market numbers — 19.0/29 in NYC and 25.1/38 in Chicago — reveal a massive number of TVs in those massive markets were tuned into the ballgame. In the Big Apple, TBS got its best ever local baseball result — including Yankees games. In the Windy City, the result was the best any MLB game has done since the White Sox won the World Series a decade ago.

On the Big 4 and the CW, NBC was the winner Tuesday night in adults 18-49 with a 1.8/6 rating, while CBS (1.7/5) was No. 1 among total viewers with 12.52 million watching. That tight demo victory for NBC came out of Best Time Ever With Neil Patrick Harris (1.2/7) and The Voice (2.6/8), the night’s top-rated show, holding even with last week even with the booming baseball numbers. NBC pretty much ended the night steady, with 10 PM’s Chicago Fire (1.7/5) dipping 6% in the demo from its Season 4 premiere last week and winning its slot.

Fox saw no dip nor uptick last night with Grandfathered (1.0/4), The Grinder (0.9/3) and Scream Queens (1.0/3) all even with their October 13 episodes when they and everyone else on primetime faced the first Democratic debate on CNN. The CW’s The Flash (1.4/5) and iZombie (0.5/2) were also flat with last week, with the latter matching its series low.

On ABC, it was Halloween a little early and late with the yearly showing of It’s The Great Pumpkin, Charlie Brown (2.0/7) special kicking off the net’s night. Dipping 9% from last year’s airing on October 15 (a Wednesday), Great Pumpkin was followed by the Toy Story Of Terror (1.6/5) special, which was steady with its October 15, 2014 broadcast when it led the Charlie Brown special on the schedule. Both specials were up double digits from last week’s Muppets and Fresh Off The Boat by 54% and 14%, respectively. Marvel’s Agents Of S.H.I.E.L.D. (1.5/7) rose 7% from its October 13 episode. Next week the debut of Wicked City will take over the 10 PM slot where ABC has been showing Shark Tank repeats the past few weeks.

While even with its October 13 episode, CBS’ NCIS (2.1/7) was tops for the night in viewers with a 5% rise over last week to 16.87 million. NCIS: New Orleans (1.6/5) was also even with last week among 18-49s while freshman Limitless (1.3/4) slipped 7% to what is a low in fast nationals.

See you at the TV ballpark tonight!
