Mayweather vs Guerrero undercard: Live stream, results, and round-by-round coverage

Tonight, starting at 7:00 pm EDT on Showtime and continuing at 9:00 pm EDT on Showtime PPV, as well as BoxNation in the UK, we'll have live coverage of the Mayweather vs Guerrero undercard, featuring a featherweight title fight between Daniel Ponce De Leon and Abner Mares.

Ponce De Leon (44-4, 35 KO) is defending the WBC title, and trying to stop Mares (25-0-1, 13 KO) from winning a world title in a third weight class at age 27. For reference, Floyd Mayweather didn't win titles in his third weight class until age 28, though this ignores that Mayweather spent significant time defending at super featherweight and lightweight. See how easy it is to be a PR person and just say stuff that sounds good with no depth or substance?

Also on the PPV undercard, Leo Santa Cruz (23-0-1, 13 KO) faces Alexander Munoz (36-4, 28 KO) at super bantamweight, and J'Leon Love (15-0, 8 KO) takes on Gabriel Rosado (21-6, 13 KO) at middleweight. Both fights are scheduled for 10 rounds.

The main event will be covered in another thread, to avoid lag in the comments section, particularly for those following on mobile devices tonight. We'll see you this evening!
