Defending champion Retief Goosen of South Africa and Americans Olin Browne and Jason Gore share the lead after the second round of the U.S. Open golf tournament, the second major tournament of the year. The Pinehurst Number Two course left many of the top players wondering if they would make it to the weekend.

Goosen fired an even par 70 in the second round while Browne was one-over-par 71 on the famed Number-Two course in Pinehurst, North Carolina. Gore shot a three-under-par 67 in his second round. All three golfers are two-under-par 138 for two rounds.

Goosen said after his round that he will have to control his shots from the tee to the green if he hopes to repeat as champion. "Uh, I probably need to drive it a little bit better than I did today. I missed a lot of fairways out there. But I got a few breaks in the rough and I was able to get it onto the green. But it is not going to happen every time so I need to drive it a little bit straighter tomorrow," he said.

South Korea's K.J. Choi is tied with Australian Mark Hensby at one-under-par 139. Choi had an even par 70 while Hensby was two-under-par 68 in his second round.

World number one Vijay Singh of Fiji is one of four golfers tied for sixth at even par, 140 for the tournament. Spain's Sergio Garcia, Lee Westwood of England, and Michael Campbell of New Zealand are tied with Singh. The world No. 1 player says he thinks that a score of even par might be enough to win the tournament. "Even par is a good chance. Depending on the weekend, really. Depending on whether it is going to rain or if it is going to blow a little harder. If it blows, then obviously it (the winning score) is going to go higher than what we predict. But I still think even par is going to have a good chance," he said.

World No. 2 Tiger Woods of the United States is part of a large group of golfers tied for 10th place at one-over-par 141 for the tournament. Last year's Masters' champion, Phil Mickelson, had a miserable day shooting seven-over-par 77 and finishing at six-over-par 146 for the tournament.

Mickelson finished second behind the late Payne Stewart the last time the Open was played at Pinehurst in 1999. Stewart died in a plane crash a few months after capturing the tournament title.
