I’m sitting here at 8:30 a.m. ET listening to the first men’s semifinal between the world’s number two and three players on Radio Roland Garros over the web.  The announcers are very good, just comparing Nadal’s dominance of Djokovic as a duck hunter who is stalking a duck and taking his time before shooting (Nadal is up 6-4, 2-1 and is rolling), but tennis is a game you have to see to enjoy.  The match started at 7 a.m. ET, but is not being carried live on U.S. television, apparently due to the wisdom on NBC, whose “live” coverage begins at 10 a.m. today (of course, these are the same people who apparently think that Mary Carillo and Dick Enberg are good announcers).  In a tournament that has been on virtually around the clock for two weeks, NBC is doing an injustice to American tennis fans who have followed the tournament for two weeks.  If they don’t want to carry the semifinals live, they should let the Tennis Channel or Versus or another network would do it have the rights.  To complain to NBC, e-mail them at nbcsportshelp@nbcuni.com.
