Round 1: McCullough lets Aoki wade in way too far, almost to a point where it's baffling why McCullough didn't unleash the fury. Aoki trips up McCullough, gets the takedown, and now in top control. Moves to half guard, was trying to sink his arm underneath McCullough's chin. Aoki postures up, lands a few blows to McCullough's face. Now a scramble, but Aoki can't improve his position. Aoki tries again and gets mount. McCullough miraculously escapes. Back down he goes. Aoki working inside half guard. Aoki passes to side control, but McCullough doing a good job of defending. McCullough flips over and gets up to all fours. Aoki lands brutal knees to the noggin, then takes the back and chokes out McCullough. Shinya Aoki def. Rob McCullough via submission (neck/face crank), Round 1.
