FORMER two-time WBC super-flyweight champion Srisaket Sor Rungvisai remains on course for a shot at his old title later this year. Headlining a Matchroom and Nakornloung co-promotion at the Workpoint Studio in Bang Phun, Thailand, the heavy-handed southpaw forced his Thai compatriot, Kwanthai Sithmorseng, to retire after three rounds of a scheduled 10-rounder. The bout opened with both fighters meeting in centre ring and exchanging blows, and neither man demonstrated a particularly sound defence. Srisaket, 34, followed up stiff jabs with arcing hooks to the ribs and corkscrew uppercuts to the jaw. Straight shots penetrated Kwanthai’s guard, as the 38-year-old from Bangkok attempted to stem the flow of punches coming his way by covering up and working his opponent’s midsection.
