Since the turn of the millennium we've had 3 notable fights falling on December 15th.
Arguably the biggest of those was also the most recent and came in 2012 when Filipino icon Nonito Donaire managed to retain the WBC Super Bantamweight title with an easy and one sided beat down of all-action Mexican Jorge Arce. Following the bout Arce announced his retirement from the ring though quickly returned to action and has since fought 4 times, including a notable loss to Jhonny Gonzalez earlier this year. For Donaire was his last at Super Bantamweight and since then he has gone 2-2 in bouts with a trio of those contests coming at Featherweight.
Back in 2007 we saw Filipino fighter Bert Batawang come up short in an IBF Light Flyweight title bout against Ulises Solis. This was the first meeting between the two men and was an easy win for Solis who stopped the Filipino in the 9th round following a very one sided bout. The most impressive thing that Batawang did was take punishment and he was never in the fight. A rematch in 2010 saw Solis stopping the Pinoy in just 6 rounds.
In 2001 we saw Thailand's Ratanachai Sor Vorapin come up short against American fighter Tim Austin in what was the Thai's second world title bout. It wasn't until May 2004 that Ratanachai would eventually win a world title, in what was his 64th professional bout and his third world title shot.
