Keep that card

Justin Rose: The 2013 U.S. Open champion and 2016 Olympic gold medalist shook off a pair of bogeys on the front nine in a big way. The Englishman birdied five of his final seven holes, including Nos. 17 and 18 to complete a 5-under 67. It was the best round of the day, and he leads by a stroke.

Toss that card

Phil Mickelson: He played alongside Jordan Spieth, and it’s as if the young star swiped momentum from the veteran. Mickelson began his day with a pair of birdies, then made double-bogey at No. 3 and plodded his way to a 2-over 74 while Spieth shot his way into contention with a 68.

On the course with ...

Rory McIlroy: Seeking the career grand slam, McIlroy is six shots back but oh, what might have been. McIlroy switched from an 8-iron to a 9-iron at the last moment for his approach into No. 5 . He left the shot 40 feet short and three-putted for bogey. On No. 7, his sand shot caught the slope and ran 65 feet away from the hole, leading to a double bogey. On the back nine, he striped a pair of 300 plus-yard drives straight down the fairway on Nos. 13 and 15, yet made only par on both holes. McIlroy also missed a 10-foot birdie putt on No. 14 and a 5-foot birdie putt on No 11, the toughest hole on the back nine.

Masters moment

Jason Day regained his stride Saturday with a 3-under 69, only his second score in the 60s in his past 17 rounds at Augusta. He’s well down the leaderboard at 3 over for the tournament — and few seemed to notice. While the former world No. 1 got to work, most patrons were still settling up in the merchandise tent or picking up breakfast. An odd number of players on the weekend meant Day was first off the tee and played alone with a non-competing marker. What did people miss? Day had a run of five birdies over a four-hole stretch. The highlight was a shot from behind the trees on the left side of the 15th hole that landed 30 feet from the pin and led to a tap-in birdie.

Chip shots

• Rickie Fowler and Ryan Moore each birdied all four of the par-5s.

• Ernie Els, 47, finished a disastrous 11-over-par round with a 65-foot birdie putt.

• The Masters purse increased for the first time in two years, from $10 million to $11 million. The winner will receive $1.98 million.

Key hole

Par-5, 510-yard No. 5: After two days of brutal winds and relatively high scores, patrons begged for some action. And they found it at No. 13. The hole played nearly a half-stroke under average, with nearly as many birdies (24) as pars (26).

Quote of the day

“They Tiger-proofed this course years ago. You can’t really Jordan-proof it.”

— Spieth, on not overpowering Augusta National.

Tweet of the day

“No Tiger. DJ gets hurt. Rory and Phil play aimlessly. And the Sunday leaderboard is STILL awesome. The Masters is so so great.”
