Gary Antuanne Russell puts his WBA super lightweight belt on the line against Andy Hiraoka, and this one comes down to who controls the first half. Russell won his title by keeping fights tidy, picking spots, and not chasing. Hiraoka steps in behind straight shots and stays compact, which can crowd fighters who prefer space. Martin has to stay patient, keep his balance, and not load up looking for praise from the crowd.
