Seiji Sugiman-Marangos (Franco/Behring Jiu Jitsu):
“I first came across Matt’s (Aeso) rants on the virtues of the crucifix position and reverse omoplata as a white belt with less than a year’s experience in jiujitsu. I thought that the technique looked really cool and began looking for the position during rolling. It wasn’t until I used the technique to win a match while I was still a white belt that I started taking the position seriously and began corresponding with Matt to troubleshoot the technique as well as working with my coaches: Shah Franco, Marco Costa and Richard Nancoo, on integrating it into my game.
“For the past few years I’ve slowly been accumulating wins by reverse omoplata in the blue and purple belt divisions of the local tournament circuit. Ever since I had my first professional MMA bout last year I’ve had the thought in the back of my mind that one day I’d like to finish a fight by reverse omoplata. During my most recent fight, hitting the technique was the furthest thing from my mind, but when I felt my opponent’s arm grab my leg I went to the position instinctively. After executing the technique I think I was probably as surprised as my opponent as well as everyone else in attendance.
“The reverse omoplata is not a complicated or gimmicky move (most people learn how to front roll in their first BJJ class). Although it may appear risky, I find that the most difficult part of the technique is the initial arm trap and not the roll-through, which is where you risk losing dominant position. I wouldn’t advocate giving up back control with hooks (although I have been tempted in the past) but the reverse omoplata has been one of my main options from side-ride for almost as long as I have been training.”
