Through round one Lee Westwood, the No. 3 golfer in the world, is the leader of the 2012 Masters tournament at Augusta National, starting things 5-under par with a first-round 67 on Thursday. Peter Hanson of Sweden tied for second with Louis Oosthuizen at 4-under, with Americans Ben Crane, Jason Dufner, and Bubba Watson shooting first-round 69s to top the more patriotic side of the leader board.

Some big names were visible nearby—Jim Furyk and Vijay Singh each shot 70s, with Rory McIlroy at 71 and Tiger Woods back at 72 in a frustrating but definitely recoverable even-par first round. The second round is already underway Friday morning, with Westwood maintaining a narrow lead at even par through his first few holes. Singh birdied the third hole to move one step closer to the top early on.
