Self-styled eccentric and golf innovator Bryson DeChambeau has ridden his "bulge and roll" technology wave all the way to the Masters halfway lead.
With custom-made, 3D-printed "face-bulging" irons never before used in professional golf, DeChambeau eked out a second-round even-par 72 in brutal conditions to remain on track for a second major championship to go with his 2020 US Open crown.
The sport's so-called "Mad Scientist" shares the lead at six under with world No.1 Scottie Scheffler (72) and fellow American Max Homa (71) as ferocious winds claimed a raft of big-name victims at Augusta National on Friday.
