Team Europe's Ryder Cup great hope Jon Rahm struggled on the first day of the Fortinet Championship.
Rahm, who will peg it up for Padraig Harrington's Europe in Whistling Straits, carded a level par opening round of 72 in Napa.
The Spaniard struggled to get anything going at the Silverado Resort and Spa North Course in California.
His day was dogged by poor putting and a few unlucky breaks.
The most eventful part of his round seemed to be when a spectator was unaware they were standing in line of his shot.
He made the turn at 1-under but made two bogeys on the back to finish several shots behind early leader Chez Reavie.
Reavie opened up his first round of the new PGA Tour season with a 65 (7-under-par).
