In order to shut down the underhook used by Rafael Sapo on the half-guard, Leo Tunico wraps his partner’s arm in a whizzer. Sapo takes advantage and traps Tunico’s arm. Note that the guard player immediately hip-escapes, repositioning himself under Tunico. This detail is key for Sapo to have the necessary leverage to spin his body and unbalance Tunico with ease, ending the sweep on top — two to zero.
