Tim Tszyu will enjoy his fourth straight Showtime headliner, this time as a full titleholder.

The American cable network confirmed its stateside coverage of Tszyu’s upcoming WBO junior middleweight title defense versus streaking contender Brian Mendoza. The previously announced bout will headline a Showtime Boxing International show on October 14 from Gold Coast Convention Centre in Broadbeach, Australia (October 15, locally).

As previously reported by BoxingScene.com, the show will also include a 12-round featherweight bout between unbeaten Sam Goodman (15-0, 7KOs)—the IBF junior featherweight mandatory challenger—and former title challenger Miguel Flores (25-4-1, 12KOs).

Event handler No Limit Boxing formally announced the show in late August, at the time with Tszyu’s interim WBO title believed to be at stake. It was since confirmed that Sydney’s Tszyu (23-0, 17KOs) will be upgraded to full WBO titlist the moment undisputed 154-pound king Jermell Charlo enters the ring for his challenge of Saul ‘Canelo’ Alvarez’s fully unified super middleweight championship on September 30 in Las Vegas, Nevada.

Tszyu was afforded the opportunity to remain active while previously waiting out a mandatory title shot. He was due to challenge for all the belts on January 28, but Charlo (35-1-1, 19KOs) had to postpone—and cancel altogether—due to a broken hand suffered during training last December,

The bout versus Mendoza (22-2, 16KOs) will mark Tszyu’s third straight from his Australia home country. He claimed the interim WBO title in a ninth-round knockout of Tony Harrison atop a March 12 Showtime telecast from Qudos Bank Arena in Sydney. He needed just 77 seconds for his latest win, a blistering first-round knockout of Carlos Ocampo also on Showtime from the very Gold Coast venue that he will host this next outing.

Mendoza has won three straight and is at the hottest point of his career.

The 29-year-old Albuquerque native—who now lives and trains in Las Vegas—scored a dramatic, one-punch knockout of unbeaten Sebastian Fundora in the seventh round after losing every round to that point in their April 8 Showtime main event in Carson, California. In his previous outing, Mendoza scored a fifth-round knockout of former unified 154-pound titlsit Jeison Rosario last November in Minneapolis.
