Industry sources confirmed that viewership on the premium-cable channel peaked during the evening's main event between Strikeforce welterweight champion Nick Diaz and Brazilian slugger Evangelista "Cyborg" Santos.
Overall, the event averaged 561,000 viewers, which is more than any single Strikeforce event broadcast on Showtime in the past year.
The peak viewership was the second-highest ever earned by a Strikeforce event on Showtime, ranking just behind 2009's female championship fight between Cristiane "Cyborg" Santos and Gina Carano, which drew a Strikeforce record 856,000 viewers during the main event and averaged 576,000 viewers for the card.
Obviously, Herschel Walker still is making a difference for Strikeforce, as the last card Nick Diaz headlined, against K.J. Noons in October, averaged 350,000 viewers. This is a good sign for Strikeforce as they head into what is going to be a crucial stretch for the promotion with the beginning of the Heavyweight Grand Prix in just over a week.
