When Tennis Channel coverage ended in the U.S. today, at 11:00 a.m. my time, "coverage" was picked up by ESPN2. Except ESPN showed only matches that had already been played. This was beyond infuriating. Fortunately, there was live coverage online at TennisChannel.com, and at ESPN3 (formerly ESPN 360), although ESPN3 did not show the Dementieva match, which was on the schedule.
I was able to see some good matches in spite of ESPN, but no one showed the Rezai-Petrova match. (I'm sure Direct TV did, but I don't have it.) There it was, a thriller by anyone's standards, and on U.S. cable television, it didn't exist.
At first, when I saw Serena Williams on ESPN, I thought "oh, there they go again--assuming that all we want to see are matches with U.S. players in them." But ESPN went on to show replays of all kinds of matches--just nothing live.
