Bryson DeChambeau opened with an 8-under-par 63 to take a one-shot lead over fellow major champions Cameron Smith and Jon Rahm at LIV Golf Mexico City on Friday. DeChambeau eagled his first hole of the day, the short par-4 second at Club De Golf Chapultepec, and was 4 under through three. He carded just one bogey before finishing birdie-birdie-par-birdie. In the thin air of Mexico City, DeChambeau averaged 370 yards per drive with three 400-yard drives, per a reporter. “Yeah, 370 is about right,” DeChambeau said.
