Day one of Major League Baseball's postseason saw ratings fly out of the park, particularly among younger viewers. Among viewers 18-34, the number of viewers climbed 32 percent over last year. The League Division Series triple header produced the biggest audience for TBS this year and was the most-watched day one of the LDS since 2005, according to Nielsen research. The three games averaged 4.93 million, with 6.6 million tuning in for the Minnesota Twins/New York Yankees game in primetime, up 23 percent over last year's opener in the same time period. Earlier in the day, the Cardinals/Dodgers game drew 4.97 million viewers, up 12 percent from last year, while the Rockies/Phillies game was even with last year.
