Mahan leads U.S. Open

Hunter Mahan was even-par through three holes at the U.S. Open on Sunday and is alone atop the leaderboard.

Mahan 2-putted for par on the first two holes, then got up and down for par on the long par-3 third.

Charl Schwartzel, the 2011 Masters champion, rolled in a 6-footer for birdie at one, but gave that shot back at the third when he 3-putted from about 40 feet out. He then bogeyed the fourth to fall one back at plus-1.

Overnight leader Phil Mickelson also 2-putted for par on the first two holes. At the third, he found sand off the tee and could do not better than 40 feet with his sand shot.

Mickelson 3-putted for double bogey to fall to 1-over-par and a share of second place with Schwartzel.

Hideki Matsuyama matched the low round of the week on Sunday as he closed with a 67 to end at 7-over 287. He is the clubhouse leader at this point.
