Rory McIlroy was the mid-day leader of the Masters, shooting a 7-under 65.

The question for the 21-year-old from Northern Ireland now is whether he can avoid a stumble like the one he experienced at the British Open last summer. At St. Andrews, he opened with a 63 but shot a second-round 80 and finished third.

Retief Goosen, who started the day with an eagle, finished with a 2-under 70. Tiger Woods finished the day with a 1-under 71.

Filed at 11:24 a.m.

Retief Goosen began his first round at the Masters nearly perfectly — with an eagle on the opening hole — and is the very early leader at 5-under through eight holes.

Ross Fisher was at 4-under 16 holes; Rory McIlroy also was at 4-under through nine.

Tiger Woods, who hasn’t won in 20 events over the last 17 months, parred the first four holes.

Phil Mickelson, the defending champ, tees off at 1:48 p.m.

Martin Kaymer, the world’s top-ranked player and PGA champion, has missed the cut in his three previous appearances in Georgia.

Conditions are perfect, Barry Svrluga tweets that it’s “calm, sunny, not too hot.” (It’s okay to hate him a little for that.)
