In a rather crass display of greed, based on the knowledge that the average consumer only cares about the main event, the "Mayweather vs. Pacquiao" undercard, which took place on Sat. night (May 2, 2015) in Las Vegas, Nevada, featured a pair of mismatched "showcase fights," one of which was a superior spectacle to the other.
The co-main saw Leo Santa Cruz, a consensus top-5 super bantamweight, face Jose Cayetano, who's lost two of his last four fights and isn't even in the top 100 at the weight. Santa Cruz (30-0-1, 17 KO) was his usual hyperactive self, firing off a huge number of punches to the head and body.
