Former champion Celestino Caballero is back in Panama, and started his second phase of camp. He returns home after several weeks of hard work in Las Vegas with trainer Jeff Mayweather. Caballero is training at the Jose 'Maco' Grove Gym for his upcoming duel with Argentina's Jonathan Barros, recognized as the "regular" world featherweight title champion of the World Boxing Association (WBA). The fight happens on the 18th of June in the champion's backyard of Mendoza, Argentina. Caballero weighed in at 137.5-pounds, only 11 pounds above the featherweight limit of 126. Jeff Mayweather arrives in Panama to re-join Caballero's camp on May 21.
