Halfway through the 2020 WGC-Mexico Championship, Bryson DeChambeau is in sole possession of the lead with a 36-hole score of 11 under par.
The California native carded a 63 on Friday that included six birdies over his final nine holes to move up three spots from his first-round position.
As impressive as DeChambeau's round was, it was only good enough to tie for the second-lowest score of the day. Patrick Reed matched DeChambeau's 63 and is tied with Erik van Rooyen for second place at 10 under par.
Van Rooyen carded the best score of the second round with a bogey-free, nine-under-par 62.
