The Leo Santa Cruz vs Abner Mares fight on ESPN this past weekend peaked at 1.6 million viewers, drawing in an average rating of 1.2 million for the entire show. The card is the highest on ESPN that the PBC has delivered to date though some critics are skeptical. Some feel the fight should have done more considering HBO brings around the same number of viewers with almost 100 million less subscribers.
Regardless, the number is good for ESPN, which hasn't seen a rating like that since the late 90's.
