Julie Mezabarba vs. Jenelyn OlsimThere are few better ways to announce your arrival to a new promotion than by defeating the most experienced star on the roster, and Julie Mezabarba did just that. The 28-year-old fended off a spirited Mei Yamaguchi enroute to a ninth professional win in a Grand Prix alternate bout.Unfortunately, she failed to repeat that performance in her sophomore outing. Mezabarba was beaten by Stamp Fairtex in the Grand Prix semifinals. She stepped in to replace South Korean Seo Hee Ham, who withdrew from the tournament due to injury.Stamp outclassed Mezabarba in the grappling and striking department, and after three rounds the Thai fighter earned the unanimous decision. Perhaps with a longer training camp, the Brazilian megastar could have turned in a greater performance.
