Junior bantamweight titlist Jose Carita Lopez (39-7-2, 32 KOs) of Puerto Rico will make his first defense against the Philippines' Marvin Sonsona (13-0, 12 KOs) on Sept. 4 at Casino Rama in Rama, Ontario, according to Sonsona promoter Sampson Lewkowicz. Lewkowicz, who first brought Filipino icon Manny Pacquiao to the United States, believes Sonsona "is a future star of the Philippines, by far," he said. "Nobody in America believed in Pacquiao when I did, and I also believe in Sonsona."
