The power of CBS came through for the Floyd Mayweather Jr. vs. Robert Guerrero promotion. On Saturday night (8:00-9:00PM, ET/PT), CBS aired a one-hour documentary about the life of undefeated Mayweather. While Showtime's "All Access" series has failed to secure the expected numbers, CBS grabbed a huge draw of 1.73 million viewers, according to TV By The Numbers. CBS came in a close fourth in the nightly rating, being edged by NBC's Smash, which grabbed a rating of 1.89 million. Mayweather's special, among the other channels, were also up against NASCAR on FOX, which blew everyone away with a 5.39 million.
