2009-08-29 Celestino Caballero w rtd 7 Francisco Leal, Calafia Bullring, Mexicali, Baja California, Mexico - WBA/IBF
On 29 September at the O2 Arena, Dublin, Ireland, Poonsawat Kratingdaenggym, the WBA ‘interim’ champion, knocked out Bernard Dunne inside three rounds to pick up the latter’s ‘second tier’ crown. Kratingdaenggym successfully defended the WBA ‘second tier’ title when outpointing Satoshi Hosono at the Big Site, Tokyo, Japan on 11 January 2010.
A few weeks later Caballero forfeited the IBF title on 5 February 2010 when failing to agree to a defence against Takalani Ndlovu within the regulatory timescale, following which the latter was matched against Steve Molitor to find a successor.
On 20 May 2010, Kratingdaenggym successfully defended the WBA ‘second tier’ title when stopping Shoji Kimura inside four rounds at a make-shift arena in Maha Sarakham, Thailand. However, on 2 October 2010 he lost the ‘second tier’ crown when outpointed over 12 rounds by Ryol Li Lee at the Korakuen Hall, Tokyo, Japan.
This was followed by Guillermo Rigondeaux winning the vacant WBA ‘interim’ title when outpointing Ricardo Cordoba on points over 12 rounds at the Cowboys Stadium, Arlington, Texas on 13 November 2010.
