The first wave of golfers have completed their second rounds at The Olympic Club in San Francisco, and no one has been able to come close to Michael Thompson, who is still atop the leaderboard at minus three.
Thompson has just begun his second round, and is at plus one through his first three holes on the round.
Some golfers in the morning wave have continued to put themselves into contention including Jim Furyk who shot one-under par to be at minus one entering the weekend. Other golfers in the morning session continued to struggle, including Rickie Fowler, who is shooting six-over through 17 holes and sits at plus eight for the tournament.
Tiger Woods is well within reaching Thompson and just teed off on his second round. He shot par on the first hole of his round.
