PINEHURST, N.C. (AP) -- The opening round of the U.S. Open at par-70, 7,562-yard Pinehurst No. 2:
LEADING: Martin Kaymer birdied six holes, including three of the last five, en route to a 65.
DRIFTING: Top-ranked Adam Scott shot 73. Masters champion Bubba Watson floundered to a 76.
WHERE'S PHIL? Mickelson, a runner-up at the U.S. Open a record six times, had an even-par 70.
AND TIGER? Woods continues to recover from back surgery, and has now missed six majors.
KEY STAT: The 15 players under par were the most to shoot in the 60s in a U.S. Open opening round since 24 players managed the feat in 2003 at Olympia Fields.
SHOT OF THE DAY: McDowell, a former U.S. Open champion, knocked his 3-wood to 12 feet at the par-5 fifth and made the putt for eagle.
WHO'S THE KID?: Matthew Fitzpatrick, a 19-year-old who looks even younger, led the amateur brigade with a 71.
NOTEWORTHY: Defending champion Justin Rose, who held off Mickelson a year ago at Merion, shot 72. There hasn't been a repeat winner in this championship since Curtis Strange in 1988-89.
QUOTEWORTHY: ''I had a lot of fun today. You don't normally say that at the U.S. Open.'' - 20-year-old Jordan Spieth, who shot 69.
