In most jiu-jitsu competitions the only leglock that is permitted for blue and purple belts is the straight ankle lock. Toeholds and kneebars are reserved for brown and black belts only, meaning many people don't even start learning leglocks until they're already considered  "advanced" jiu-jitsu practitioners. 

One of the smaller competitors in his division, Pedro Machado conquered the +180lb blue-purple bracket to win at World Series of Grappling. 

Mahamed Aly and Manuel Ribamar were the big winners at the second World Series of Grappling event, each taking home $20,000 grand prizes for winning their divisions. 

Here are the finals matches from World Series of Grappling. For all match videos please click here (please note, some matches still to be uploaded. Check back soon for updates). 

With brackets as loaded as these, anything could happen. That's why whoever comes out on top will be the winner of an instant classic.

2018 has belonged to Isaque Bahiense (Alliance). Riding a 27-match win streak and with tens of thousands of dollars of winnings in his bank account, the 22-year-old is a World, European and Abu Dhabi World Pro champion. 

The big money offered by World Series of Grappling has brought out 2017 IBJJF World champ Nicholas Meregali, who is making his first competition appearance since Worlds. 

Brace yourself, grappling fans. We could potentially see Keenan Cornelius go up against Mahamed Aly and Nicholas Meregali this weekend. 

A new event is promising to raise the stakes for jiu-jitsu athletes and the biggest names in the game are getting involved.
