Tony Harrison and Paulie Malignaggi round out July 30 Showtime card

After Saturday’s Keith Thurman-Shawn Porter welterweight title fight drew the largest television audience of the year on CBS, promoter Lou DiBella said he’s secured more action fights for the next card at Brooklyn’s Barclays Center.

On Tuesday morning, Showtime announced the remainder of the undercard leading to the July 30 World Boxing Assn. featherweight title main event between champion Leo Santa Cruz (32-0-1, 18 knockouts) of Los Angeles and Carl Frampton (22-0, 14 KOs), a super-bantamweight champion from Ireland.

It was confirmed Saturday that Riverside’s former two-division world champion Mikey Garcia (34-0, 28 KOs) will mark his comeback from a two-year-plus contractual/legal dispute with his former promoter by fighting former featherweight champion Elio Rojas (24-2, 14 KOs) in the co-main event.

Also on the Showtime triple-header will be Detroit middleweight Tony Harrison (23-1, 19 KOs) meeting Sergey Rabchenko (27-1, 20 KOs).

Preceding that, on Showtime Extreme, network analyst and former welterweight champion Paulie Malignaggi (35-7, seven KOs) will fight 35-year-old Gabriel Bracero (24-2, five KOs) in an all-Brooklyn bout.

And the first women’s world-title fight at Barclays Center will be staged between Brooklyn-based featherweight world champion Amanda Serrano (28-1, 21 KOs) and challenger Calixta Silgado (14-6, nine KOs).

Ukrainian super-lightweight Ivan Redkach (19-1-1, 15 KOs), who resides in Los Angeles, will also be on the undercard against an opponent yet to be announced.
