LEADING: Defending champion Jordan Spieth fired a bogey-free 6-under par 66 to take a two-stroke lead over Danny Lee of New Zealand and Shane Lowry of Ireland. It’s Spieth’s fifth straight round in the solo lead, a Masters record.

LURKING: 2015 Zurich Classic of New Orleans champion Justin Rose, who tied for second last year, is at 3-under 69. Rory McIlroy, trying to complete the career grand slam with a win this week, is four back at 70.

SHOT OF THE DAY: Spain’s Sergio Garcia blocked his tee shot into a grove of trees right of the par-4 18th fairway but punched out to the back of the green from 158 yards out. He got down in two to save par and preserve a 3-under 69 that kept him in a tie for fourth.

BOGEYS AND BIRDIES: Thursday’s scoring average of 74.09 was higher than the all-time scoring average for all Masters tournaments (74.01).

CUT DAY: The field of 89 players will be reduced to the low 50 and ties following Friday’s second round.

INCREDIBLE STAT: Four-time major champion Ernie Els had a 9 on the 445-yard par-4 first hole, putting six times from three feet or less. It is the highest score ever on Augusta National’s opening hole.

THE LAST WORD: “I would have signed for 2-under today and not even played the round knowing the conditions that were coming up. Got a lot out of the round with what I felt was average-ish ball striking. I felt like we stole a few.”
