Sparks will fly when HBO Sports spotlights world-class performers on WORLD CHAMPIONSHIP BOXING: SHANE MOSLEY VS. RICARDO MAYORGA AND ANDRE BERTO VS. STEVE FORBES, presented live SATURDAY, SEPT. 27 (10:30 p.m. ET/7:30 p.m. PT) from The Home Depot Center in Carson, Cal., exclusively on HBO. The WORLD CHAMPIONSHIP BOXING team will be ringside for the event, which will be presented in HDTV and in Spanish on HBO Latino.

Expect a September heat wave when former lightweight, welterweight and junior middleweight champion “Sugar” Shane Mosley (44-5, 37 KOs) stands toe-to-toe with Ricardo “El Matador” Mayorga (28-6-1, 22 KOs), one of boxing’s most animated fighters, in a 12-round junior middleweight bout. In his first fight in Southern California since 2000, Pomona, Cal., native Mosley returns to the ring in search of another title shot. A native of Managua, Nicaragua, Mayorga hasn’t fought since handling Fernando Vargas last November. He’s never ducked a challenge, having tangled with Vernon Forrest, Felix Trinidad and Oscar De La Hoya.

In the opening bout, newly crowned welterweight titleholder Andre Berto (22-0, 19 KOs) defends his belt against crafty veteran Steve Forbes (33-6, 9 KOs) in a 12-round, 147-pound tilt. Florida native Berto captured his first title by defeating never-before KO’d Miki Rodriguez in June, scoring his 19th knockout in just 22 fights. Las Vegas resident Forbes elevated his status significantly (NOT MY WORDING.–ED.) last May when he went the distance against Oscar De La Hoya.
