DeChambeau notched a double bogey and bogey in the first nine holes of the Masters.
Leading up to the 85th Masters Tournament, Bryson DeChambeau was excited to use his prototype Cobra's driver to improve his consistency on off-center strikes.
However, DeChambeau imploded halfway through the first nine holes of the tournament and sits 4 over through 15 in the first round of the tournament.
DeChambeau, ranked No. 5 in the world and playing in his fifth Masters, parred through the first three holes before imploding with a double bogey and bogey in holes four and five and a second bogey at the par-5 8th.
On the back nine, he parred through holes 10 and 11. DeChambeau managed to stay even before recording his third bogey of the day at the par-3 12th.
The 27-year-old parred at holes 13 and 14th before getting his first birdie at the par-5 15th.
For all his success during his career, DeChambeau has struggled at Augusta National. His best finish there came in his first Masters, when he finished tied for 21st.
