Tszyu upsets Spence by decision in Sydney comeback fight

Former WBO junior middleweight champion Tim Tszyu beat Errol Spence Jr. by unanimous decision Saturday night in Sydney, derailing the future Hall of Famer's comeback and putting the Australian back in line for a world title shot.

Tszyu, 31, controlled the fight against the older Spence across the scorecards. The win marks a major rebound for the Sydney native after losing his WBO belt earlier in his career.

Spence, who moved up from welterweight, struggled to find his rhythm in his first fight in months. The loss raises questions about whether the American star will continue competing or hang up the gloves.

Tszyu now positions himself as a mandatory challenger or voluntary option for any of the current junior middleweight titleholders. No timeline has been announced for his next bout.
