Bellator 284 on Friday in Sioux Falls, South Dakota, was headlined by Goiti Yamauchi and Neiman Gracie—two world-class grapplers who have developed effective, dangerous striking. While Gracie had lost two of his last three bouts, they were close decisions against two of the very best welterweights in the world: Bellator MMA interim champion Logan Storley and top contender Jason Jackson. Yamauchi moved up to welterweight with a gorgeous first-round armbar of Levan Chokheli in April, but the more established Gracie was a moderate favorite.
