Leading: Rory McIlroy and Alvaro Quiros are tied at 7-under 65.

Pursuing: Y.E. Yang and K.J. Choi are two strokes back at 67, followed by Matt Kuchar and Ricky Barnes at 68.

Where’s Tiger? Woods is six strokes off the lead at 71.

And Phil? Mickelson began defense of his green jacket with a 70.

Shot of the day: Retief Goosen started with a bang, knocking an 8-iron 161 yards from the first fairway into the cup for an eagle.

Key stat: The 67s shot by Yang and Choi were the same score both shot in the first round last year.

Noteworthy: PGA champion Martin Kaymer came in as the world’s top-ranked player, but has never made it to the weekend. He may be going home early for the fourth year in a row after a dismal 78 -- his worst score yet in the Masters.

Quoteworthy: “That would be stupid.” Quiros, whose best previous Masters round was 75, when asked whether he glanced at the leaderboard during his round.
