Postseason TV ratings up from last year

Exciting, close ballgames highlight playoff matchups

Jeff Mathis, Jimmy Rollins and the rest of the late-inning heroes have been very good for business, according to baseball's television ratings since the end of the regular season.

Including the play-in game between the Tigers and Twins, which technically was a regular-season affair, overall TV viewership is up 13 percent over last year, Major League Baseball said Tuesday. The numbers included a pair of dramatic finishes on Monday, when Mathis of the Angels and Rollins of the Phillies delivered walk-off doubles in their respective League Championship Series.

Those thrillers continued an October jam-packed with drama. Entering Tuesday's Game 4 of the American League Championship Series, 11 of the 21 games since the final Sunday of the regular season have been decided by one run.
