Aoki and Diaz weren't the first fighters to dig deep into their repertoires to unleash gogoplatas in MMA.
However, the former Dream kingpin and the former Strikeforce champ do have the distinction of being the first and second fighters, respectively, to use this unorthodox choke on a significant stage.
Aoki struck first by slapping a gogoplata, a variation of the omoplata which is set up by using Bravo's rubber guard, on nemesis Joachim Hansen at Pride Shockwave 2006.
Less than two months later at Pride 33, "The Stockton Bad Boy" laced his left leg under Takanori Gomi's right armpit before positioning the front of his shin across Gomi's trachea. Diaz finished the technique by draping his right leg across the left side of Gomi's back and then locking his hands while simultaneously lifting his hips.
Diaz choked Gomi unconscious, but the Nevada State Athletic Commission later ruled the fight a no contest after the Californian positive for elevated marijuana metabolites. Diaz hasn't hit the submission in 15 fights following the mishap.
Aoki, on the contrary, revolutionized the submission by sticking the first gogoplata in the mount position in MMA history on former Japanese Olympic wrestler Katsuhiko Nagata at Dream 4.
The ridiculously limber Aoki established a high mount and made his move by threading his right leg over Nagata's left shoulder. Aoki then used both hands to yank on the back of his head while driving his shin into Nagata's throat.
Although Nagata tapped out, he did so an instant too late, allowing Aoki to strangle him unconscious with one of the world's most uncommon chokes.
