Rose put on a clinic with the putter and ran off four straight birdies late in his round for a 7-under 65, giving him a two-shot lead after the opening round of the Arnold Palmer Invitational. John Huh had a chance to catch him late in the afternoon, but needing a birdie on the final hole, he found a fairway bunker on No. 9 and took bogey for a 67. John Rollins and Brad Fritsch were at 68. Rose and Woods played in the morning, the tougher side of the draw because of chilly temperatures and a strong breeze. Woods came up short in a bunker, hit a poor shot and took bogey on the 17th. Also in the group at 69 with Woods were Ryo Ishikawa of Japan, Nick Watney, Sean O'Hair and Bill Haas, who bogeyed his last two holes. British Open champion Ernie Els played with Rose and Woods and disappeared quickly. 9 to salvage a 75. Others weren't so fortunate. U.S. Open champion Webb Simpson and two-time major champion Angel Cabrera each had 80. Masters champion Bubba Watson birdied three of his last four holes for a 74. Brandt Snedeker, playing for the first time in five weeks because of a rib injury, took triple bogey on his 17th hole and had a 76. Snedeker's 5-iron on the 17th didn't quite clear the hazard where the sand meets the lake. Coming off his injury, he wasn't interesting in trying to gouge it out, which he probably couldn't have done, anyway. At least he had his health at the end of the round. "Encouraged," he said about his ribs. Phil Mickelson felt terrible about his swing, and it showed. Even so, the four-time major champion made an eagle putt on the 16th to reach 1 under, only to throw those shots away with three-putt bogeys on the last two holes.
