The next big boxing event in the Gateway City will be this Saturday as three time world champion Juan Diaz will step in the ring at the Laredo Engery Arena. The “Baby Bull” is in town and went through a workout at Los Dos Laredos gym this afternoon for media and members of the gym. Diaz had stepped away from the sport after losing a unanimous decision in 2010 to Juan Manuel Marquez in a rematch from the fight of the year in 2009. This will be his second fight in laredo and he is excited to be back in front of a familiar crowd. The Houston native has a career record of 36-4 with 18 of those wins coming by knockout. He has held the WBO, WBA and IFO lightweight world titles.
