Maidana vs Lopez: Showtime Extreme bouts confirmed for June 8

Unbeaten welterweight prospect Yoshihiro Kamegai will meet former WBA interim junior welterweight titlist Johan Perez in the main bout of the June 8 Showtime Extreme broadcast, which will precede the Maidana vs Lopez card on Showtime.

Kamegai (22-0-1, 19 KO) is a 30-year-old banger who stole some attention last October with a great fight against Jorge Silva, who would go on to lose to Alfredo Angulo in December. As a prospect, he's a bit long in the tooth, but he takes a good shot and gives one, and he's definitely worth tuning in to see.

Perez (16-1-1, 12 KO) signed with Golden Boy last year and immediately lost to Pablo Cesar Cano in July, then took a 10-round majority decision over faded veteran Steve Forbes in January of this year.

Also televised will be 31-year-old heavyweight Gerald Washington (7-0, 5 KO), who takes a step up in competition against veteran Sherman "Tank" Williams (35-12-2, 19 KO). Williams, 40, is short at 5'11", but went 12 with Robert Helenius in November, his last fight. You may also recall Williams from a 2011 no-contest against Evander Holyfield, a fight in which Williams was doing reasonably well. He also has losses to Manuel Charr, Ruslan Chagaev, Tye Fields, and others.

If time permits, we'll also see 2012 U.S. Olympian Joseph Diaz Jr (4-0, 2 KO) in action.
