Major League Baseball’s Wild Card game hit another ratings home run last night on cable with TBS’ Chicago Cubs-Pittsburgh Pirates telecast.

TBS generated a network Wild Card game record 5.5 overnight rating for its coverage of the Cubs’ 4-0 win over the Pirates, according to Nielsen. The rating beats out TBS' previous Wild Card game high of a 4.1 rating set by the 2012 Baltimore Orioles/Texas Rangers game.

 Total viewership numbers for the Cubs-Pirates telecast will be released later today.

TBS’ Cubs-Pirates game is the highest for a TBS baseball game since the 2011 NLDS Game 5 St. Louis Cardinals/Philadelphia Phillies contest, according to network officials.

The performance comes on the heels of ESPN’s Houston Astros-New York Yankees telecast Tuesday which drew a Wild Card game record 5.7 overnight rating and 7.6 million viewers, according to Nielsen

Despite the lopsided result on the diamond, ESPN’s inaugural MLB Wild Card telecast shined as the most-watched and highest-rated game for the sport’s recent playoff format.

ESPN’s first swing in Major League Baseball’s postseason since 2006 delivered a record 3.6 U.S. rating and 5.59 million viewers for the National League Wild Card game, according to Nielsen fast nationals data.

Coverage of the Giants’ 8-0 win on Oct. 1, which ended the Pirates season, surpassed the 5.23 million viewers on TBS, who watched the Kansas City Royals’ exciting 9-8, 12th inning win over the Oakland A’s by 7%. Giants-Pirates -- San Francisco jumped out to a 4-0 lead on Brandon Crawford's fourth-inning Grand Slam (pictured)  -- was up 22% in viewership and 20% in ratings compared to the 2013 NL Wild Card telecast on TBS in which the Pirates topped the Cincinnati Reds.

MLB introduced the 10-team playoff format that includes a Wild Card game in both the senior and junior circuits during the 2012 playoffs.

The Giants-Pirates contest was also the most-viewed MLB game ever on WatchESPN with more than 9.9 million total minutes viewed and an average minute audience of 48,589. Those figures were 126% higher for total minutes and 156% higher for average minute audience than the previous WatchESPN record with baseball.
