Early on a Saturday morning at one of California’s most iconic surf breaks, a routine paddle-out turned into something nobody at the lineup was expecting.
At approximately 7:15 a.m. on May 5, 2026, Brazilian jiu-jitsu black belt Sandro Santiago was making his way into the water at Steamer Lane in Santa Cruz, California.
According to sources, Santiago holds a sixth-degree black belt in Brazilian jiu-jitsu. He described the initial exchange as calm enough. He greeted a bodyboarder and a surfer in the water before the surfer pressed him with a question.
“I jumped into the water from the cliff and approached a bodyboarder and a surfer, greeting them with a ‘good morning,'” Santiago wrote in his account of the incident. “We talked briefly for a few minutes, and the surfer asked if I remembered him. I told him I didn’t.”
The surfer’s memory, however, was sharp. He reminded Santiago of a previous run-in involving a cliff jump and a wave that Santiago felt was taken out of turn.
“He then said, ‘One day I jumped off the cliff, caught a wave, and you yelled at me,'” Santiago recalled. “I replied, ‘Yes, I probably did, because you’re not allowed to jump from the cliff and take a wave. We have a lineup here that needs to be respected.'”
What started as a brief exchange of words escalated quickly. Within minutes, the tone shifted from conversational to confrontational.
“At around 7:20 AM, he suddenly became aggressive and started chasing me in the water,” Santiago explained. “I warned him multiple times to stay away, but he kept insisting, repeatedly saying he was going to ‘kick my a*s.’ He then threw a punch at me.”
Rather than let the situation deteriorate further in open water, both men agreed to move the matter to shore. The video, which Santiago later posted to his Instagram account under the handle @sandrobatatabjj, captures both the water exchange and the subsequent confrontation on the stairs leading down to the break.
What the other surfer apparently did not know going into this encounter was exactly who he was dealing with. Santiago is not just a casual wave-catcher. He is a seasoned, highly decorated martial artist with decades of training behind him.
As one commenter put it plainly: “Imagine being such a non-local that you ignorantly pick a battle with a seasoned decorated black belt at his local break.”
On the stairs, Santiago used his grappling background to control the situation without ever throwing a punch. Viewers watching the clip noted a clean takedown followed by side control and mount, textbook technique applied in a very non-textbook setting, complete with a wetsuit.
“Before he threw the punch, I had already warned him several times, but he continued to escalate the situation,” Santiago wrote. “Throughout the entire incident, I did not throw a single punch. Instead, I restrained him and told him to apologize.”
Santiago was clear about his intentions and the philosophy that guided his response.
“As a martial artist, I don’t train to hurt people. I train to compete, to defend myself, and to teach discipline. Hurting him would not have proven anything. I was fully aware of what I could do, but I chose not to harm him.”
He added: “I chose to do the right thing, to show restraint, discipline, and respect, even when it wasn’t given to me.”
The video quickly gained traction after being highlighted by Surfer Magazine, drawing a wave of responses from the online surf and martial arts communities.
“We all surf mostly for fun, the lineup etiquette is very simple and benefits everyone. Thank you for handling this so well,” wrote one commenter.
Another noted, “He has no idea that today was his lucky day.”
“Jiu-jitsu is the best self-defense to de-escalate a violent problem in a safe and respectful manner,” wrote a commenter who identified himself as a longtime local. “I am blown away that you didn’t get caught up in his drama and hurt him. It really shows how much discipline you have and teach.”
