“I felt good,” Mickelson said. “You know, I hit some good shots, and I was able to shoot a good round. But it’s a little humbling to shoot what I thought was a good round and then get lapped by three (shots).” It was even more humbling to know that Harrington had never played in the Nissan Open and played the course only once before this week. Harrington played Riviera with friends while he was in Los Angeles for the Target World Challenge. “Obviously, someday it will catch up to me, the fact I don’t know the golf course,” Harrington said. “Today it didn’t. And whenever I did miss a shot, it seemed to be OK. There are a lot of pitfalls on this course, the catches, but they didn’t today.” Tiger Woods skipped the tournament this year, but eight of the top-10 ranked players in the world are in it and they’re playing like the best. Four of those players – Harrington, Mickelson, Jim Furyk, and Vijay Singh – are in the top 10 on the leaderboard. Furyk shot a 4-under 67 and Singh a 68. Sergio Garcia and Kevin Stadler – a USC product – are tied with Furyk and others at 67. They’re three shots behind leader Padraig Harrington, who made 10 birdies and shot an opening-round 63. This isn’t Mickelson’s hometown tournament, it just seemed like it Thursday. Mickelson and playing partners Ernie Els and Vaughn Taylor had the biggest and best gallery, with the majority of fans pulling for Mickelson. PACIFIC PALISADES – Phil Mickelson missed the Nissan Open the last five years, but he didn’t miss a beat in his return. Mickelson shot a 5-under par 66 in Thursday’s first round at Riviera Country Club and is tied for second with Briny Baird and Pat Perez. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
