Justin Gaethje  (11-0) is World Series of Fighting’s first lightweight champion after scoring a first-round stoppage over Richard Patishnock  (6-2). The bout served as the main event of Saturday’s World Series of Fighting 8 event, which took place at Seminole Hard Rock Hotel & Casino in Hollywood, Fla., and aired on NBC Sports Network. Gaethje set the tone with an early flying knee, pushing forward immediately in a non-stop barrage of offense.
