Matches are contested over the best of three sets, with the deciding set taking the form of a Champions tie-break. The Champions tie-break is an expanded version of the conventional professional tennis tie-break, whereby the winner is the first player to reach 10 points and lead by a margin of 2.
Re: ATP Champions Tour: Delray Beach (February 20-23, 2010)
I've never seen any coverage of ATP Champions Tour matches on U.S. television. The Outback Champions Series matches are regularly aired on Tennis Channel (usually from Monday-Thursday of weeks with no majors/high tier ATP/WTA tournaments.)
