Soren Kjeldsen, who just made the turn at 3 under and leads the 110th U.S. Open, isn't exactly a household name here in the States. So here are three things you should know about the 35-year-old Dane.
1) While you may be surprised to see him at the top of the leaderboard, his career-high finish on the PGA TOUR came in the 2009 PGA where he tied for sixth.
2) He's a three-time winner on the European Tour with victories in each of the last two seasons.
3) He ran a marathon in 1997 in a solid three hours, 54 minutes. He hasn't run one since, saying "Once was enough for me. I try to stay in good shape but not as extreme as that."
Kjeldsen is playing in his second U.S. Open. He has never broken par and is a combined 26 over in six rounds in the difficult and draining major. -- Helen Ross
