Guam’s local competitors will have a wealth of support as they take on some of the world’s best in the black and brown belt divisions, most notably Guam’s Javier Mirelez taking on a stacked black belt group.
“I’m truly honored to compete against some of the top Jiu Jitsu fighters in the world coming to our island. It’s a dream come true, and competing at the highest level is what I’ve been working for since I started Jiu Jitsu in 2006. I’m eager to display my skills with these world champion black belts, and most importantly grow from this experience of a lifetime,” said Mirelez on being one of the local black belts in the crop of world class fighters.
Guam’s Anthony Cruz has had a really busy, and successful past year winning two gold medals in the JBJJF All Japan Jiu Jitsu Championship and winning gold in the Abu Dhabi Grand Slam Tokyo 85 KG Brown Belt Champion. He returns home to compete in a pair of big tournaments with the Marianas Open this weekend and the Submit event next weekend.
“I’m definitely looking forward to the influx of competition coming from abroad. I aspire to be the best I can possibly be, and the only way to do that in my opinion is test yourself against the highest level of competition so I’m looking forward to the challenge. I prepare for every competition by pushing myself in the training and having absolute belief in my ability to achieve my goals,” said Cruz on his first local competition since his medal-heavy summer.
Some of the weekend’s off-island competitors have also hit the training grounds with Guam’s local talents in preparation for the big weekend. Cruz reflected on the week and not to forget the other competitors who aren’t headlining the event.
“I’m thankful for the opportunity to train with the highest levels of athletes in jiu jitsu because it gives me the opportunity to test myself against some of the best in the game. More than anything however, I’m thankful for the guys are Carlson Gracie Guam that though may not be big names in the sport yet, they show up everyday to help me improve and grow in training.
