There's not been many notable bouts in Asian Boxing falling on February 16th, there's no clear reason as to why there's so few fights on this day, but we have had a few notable ones in the last 30 years or so.
The highest profile one came in 2006 when Thai great Ponsaklek Wonjongkam recorded his 13th defense of the WBC Flyweight title, beating Gilbero Keb Baas over 12 rounds. By this point Wonjongkam had been a champion for close to 5 years and was well established as one of the great Flyweight champions of his era. Wonjongkam was 59-2 (30) entering this bout and was 28. Baas was 26-12-1 (15), also 28.
Notably Baas would go on to win the WBC Light Flyweight title in 2010 before retiring in 2012 with a record of 35-22-4 (22). Wonjongkam would run up a professional record of 91-5-2 (47), with his last fight coming in 2018 and would become a 2-time champion with a stellar record at the top level.
