The game times for this series have been a joke; if you're a 9-to-5er or schoolkid, you haven't been able to watch any of these comfortable. It'll be better going forward.
According to MLB, tomorrow's Game 4 will be played at 4:07pm ET if the Yankees/Twins series concludes today (the Yanks lead the Twinkies 2-0; they play in about two hours). If Phils-Rox is the only game tomorrow, they will play at 6:07 ET.
If necessary, Tuesday's Game 5 in Philly will be at 8:07pm.
