Are you kidding? Bud Selig would be ecstatic if the Phillies and Yankees cruise through the playoffs to the WS. In terms of effective market size (i.e. not including the Rangers because they aren't as into baseball as Philly right now) it would be the best possible matchup in terms of ratings of all the playoff teams.
Yeah, the fact that the Rays are in the mix with their low payroll gives him a reason to say how you don't have to spend like the Yankees and Sox to win. But he would also say that teams can't really be successful without a publicly financed stadium
