Ronaldo Souza
In April 2006, Alexander faced the future Strikeforce Middleweight Champion Ronaldo Souza at Jungle Fight 5. Early in the first round, Jacaré moved the fight to the ground, and got a full mount position. After some heavy ground and pound, Jacaré submitted Shlemenko by an arm triangle choke. Shlemenko didn't tap and got choked unconscious.
