I still think that baseball games get long and slow for things related to the baseball. Pitching changes, trips to the mound, batters requesting time...those are at least still baseball-related things. Could definitely shave a few seconds off of each commercial break between innings and during pitching changes, but I don't think baseball has the same type of annoyance that football does where they go to commercial after an XP and after the ensuing kickoff (to be fair, they don't do that every time, but they do it often).
When it comes to game time, I don't get the vibe that baseball is trying to squeeze every penny out of the broadcast like I do with football. Probably largely due to the fact that I watch way more local baseball which has shorter breaks than I do national baseball with longer breaks. And when the O's are in the playoffs and things get really slow, the pace of the game is not a blip on my radar.
