With part of the round of 96 taking place after the first round on Tuesday, the remainder of the programme finished with Floridan Thompson managing an 8.17/10 in a dominant heat win.
He drove through a racy barrel before finishing with two power-turns, comfortably seeing off Nic Hdez, David Rutherford and Kalani David,
“I figured it was kind of slow and there are a lot of close outs, so my game plan was to just catch waves that weren’t closing out and do as many turns as I could,” Thompson said.
“Finally I got lucky with that little barrel and I figured if I could make that it’d be a pretty good score.”
That was the highest single-wave score, but Tahiti’s Enrique Ariitu took a combined heat total of 14.67/20.
“It’s all you could to on the waves out there, to do airs,” Ariitu said. “It worked for me in that heat. It’s my first time to Mexico and I’m trying to do some comps and get some results."
The first four heats had been completed on Tuesday, with Oliver Kurtz posting an 8.83.
The third round should start on Thursday, conditions permitting.
