Tonight at 11 p.m. EST on Showtime, Rico Ramos will defend his WBA super bantamweight title in the main event of a ShoBox triple-header from the Palms in Las Vegas. We'll be here with round-by-round coverage and live results of the full card.

Ramos (20-0, 11 KO) and Rigondeaux (8-0, 6 KO) may not be a big-time marquee fight, but it's a significant fight at 122 pounds at any rate, and the winner will have a good argument for being the firm and clear No. 2 in the division, slotting in behind Toshiaki Nishioka of Japan.

In the first undercard bout of the night, super flyweights Matthew Villanueva (6-0-1, 6 KO) and Michael Ruiz Jr (8-1-1, 3 KO) will go to work in an eight-round fight. The sandwich bout is also an eight-rounder, pitting intriguing 19-year-old prospect Joel Diaz (6-0, 5 KO) against Guy Robb (7-0, 3 KO) in a super featherweight bout.

Join us this evening!
