Too much Sho for fatigued Zou

One and done.

That's a probable epitaph for Zou Shiming's professional boxing career after China's double Olympic gold medalist was stopped by 10-1 Japanese underdog Sho Kimura in their WBO world flyweight title fight on Friday night in Shanghai.

In his first bout since capturing the crown eight months ago and fighting for the first time under his own promotional banner and without Hall of Fame trainer Freddie Roach in his corner, the 36-year-old Zou (9-2) showed only abbreviated flashes of speed and power - but he was leading on two of the three scorecards when he was TKO'd at 2:28 of round 11.
