Séamus Power continued his run of good form with a near perfect start to The American Express in California, firing a bogey-free 65 to sit three shots behind the leaders after the first round.
After last week breaking into the world top 50, Power backed up his recent performnaces by carding seven birdies on his way to a round of seven under.
Graeme McDowell is one shot further back after a good round of his own. The Northern Irishman got off to a hot start with four birdies in his first six holes before picking up three further shots in his round after a rare bogey on the ninth.
Americans Lee Hodges and Patrick Cantlay topped the leaderboard after they both signed for a 10-under 62, followed two shots back by compatriot Cameron Young and South Korean KH Lee.
