Filipino strawweight bet Robin Catalan suffered a first-round submission defeat from Japanese fighter Ryuto Sawada in ONE: Unbreakable III at the Singapore Indoor Stadium Friday night.
Sawada controlled the fight using his impressive grappling skills before finishing off the Filipino with a deep rear-naked choke, prompting referee Mohamad Sulaiman to stop the match at the 4:20 mark.
The 25-year-old Sawada showed who's boss in ground game, taking down Catalan twice before executing the finisher move.
The Japanese grappler pretty much dominated the entirety of the match right after injury time at around the one minute mark, swiftly catching Catalan's front kick en route to a counter takedown.
Robin, for his part, failed to exact revenge for his teammates Jhomary Torres and older brother Rene, who both suffered back-to-back losses in ONE: Big Bang last December.
Sawada improved to a 14-5-1 record while victory remained to be elusive for the Catalan Fighting System as Robin slid to 10-7.
