Hong Kong boxing star Rex “Wonder Kid” Tso will look to extend his unbeaten streak when he takes on former world title challenger Hirofumi Mukai on 11 March.

The 29-year-old Tso (20-0-0) will enter the ring once again to headline “Clash of Champions 2” at the 8,000 seat Hong Kong Convention and Exhibition Centre in Wan Chai.

On the line is Tso’s WBO International Junior Bantamweight title (115 lbs) and WBC Asia Super Flyweight title. Mukai’s WBO Asia-Pacific Junior Bantamweight title is also on the line, making the bout a three-title fight.

Mukai (13-4-3), a former world title challenger and new WBO Asia-Pacific champion

In November 2016, Hirofumi Mukai defeated Tanawat Phonnaku to claim Tso’s vacated WBO Asia-Pacific Junior Bantamweight title.

Mukai immediately called out Tso, laying down a challenge for the WBO International Junior Bantamweight title captured by Tso at Battle of Victors on 8 October last year.

Osaka-based Mukai is no stranger to big title fights, having fought for the WBC World Flyweight and Super Flyweight titles, as well as OBPF and Japanese national titles.

At 171cm, Mukai is Tso’s tallest opponent to date, and being a southpaw, may prove to be the Hong Kong boxer’s biggest challenge yet.

Title Shot Looming?

Tso’s camp say the Hong Kong fighter is closer than ever to world title challenge.

Given Tso’s rise up the boxing rankings and his growing fame in Hong Kong and Macau, Top Rank Boxing has extended its promotional contract with Tso for an additional 12-month period.

The boxing promoter, led by founder and CEO Bob Arum, will work to set up a world title fight for Tso in 2017. If Tso successfully defends his WBO International title in March, the WBO will likely schedule a world title bout for Tso, especially if he is able to maintain his #1 contender status.


Following a sell-out show of 5,000 at Battle of Victors on last October, Clash of Champions 2 will look to set yet a new record with Hall 5BC of the HKCEC configured to seat up to 8,000.

Clash of Champions 2 will be supervised by the WBO, with the Tso-Mukai title bout also sanctioned by the WBC.

Tso is once again training at the Wakee Salud Gym in Cebu, the Philippines, with WBO Bantamweight champion Marlon Tapales among his sparring partners.

He vanquished previously undefeated top Japanese prospect Ryuto Maekawa at Battle of Victors on 8 October, 2016, and is going for his 21 consecutive win at Clash of Champions 2.
