Honestly, now that ballparks are increasingly giant malls with a baseball game in the middle, it's an open question whether owners actually want games to be shorter. Sure, they'll happily put in the extra-innings rule to eliminate those late nights where fans have stopped buying things or left altogether and they still have to pay ballpark staff, but what's their incentive to get to the seventh inning in under two hours? That only cuts into the amount of beer they can sell. The national networks like NBC or CBS that no longer want anything to do with baseball might object to games that last four hours, but now that the games are all on regional sports networks and the playoffs are on basic cable, what's the problem? I'm sure YES would rather have a Yankee game that goes 3:30 than a three hour game and 30 minutes of an old Tino Martinez interview.
