I wasn't home last night, so maybe ESPN did show that match that went until nearly 3 am Eastern. The Federer match is on ESPN right now, so I guess they are showing some night matches. It seemed like whenever I've watched, they've cut in the late afternoon and the rest of the day's coverage was on Tennis Channel.
Funny to watch Roger's father watching the match and listening to the commentators talk about him. He sat there stonefaced for a minute or two and then cracked a little smirk.
