Christos Giagos pleaded for an opportunity to return to the UFC after beating Arthur Estrazulas in the RFA 42 main event. However, his performance was on the less than thrilling side, so he might have some more work to do. Giagos (13-5), who was cut from the UFC in June 2015 after going 1-2 in the octagon, remained perfect in RFA competition when he bested Estrazulas (8-3) by unanimous decision in Friday’s lightweight headliner at Visalia Convention Center in Visalia, Calif. The event aired on AXS TV.
