J.B. Holmes kept his lead Friday at Doral. Rory McIlroy lost his cool.

Holmes was 11 shots worse than his record-tying 62 in the opening round. A bogey on the 18th hole gave him a 1-over 73, still enough to take a two-shot lead over Ryan Moore going into the weekend at Trump National Doral.

McIlroy was one club lighter than the start of his round. Frustrated by a 3-iron into the water on the eighth hole, the world's No. 1 player slung his 3-iron some 50 yards into the water. It was an embarrassing moment for McIlroy, though he the splash — from the club, not the ball — appeared to settle him. He wound up with a 70 and was eight shots back halfway through the World Golf Championship.

"I just let frustration get the better of me," McIlroy said. "It was heat of the moment. I mean, if it had been any other club, I probably wouldn't have. But I didn't need a 3-iron for the rest of the round, so I thought, 'Why not?'''

He leaned on self-deprecation to get him through one of the most embarrassing moments of his career, though Boy Wonder knew better.

Walking up the 10th fairway, he noticed his father following outside the ropes and said he mentioned to his caddie, "Wonder what my dad's going to say about that?"

"Looking back, it isn't one of my proudest moments," McIlroy said. "But you know, walked away with a bogey and regrouped and did OK."

Ciganda ties Park

Carlota Ciganda shot a 6-under 66 to move into a tie for the lead with Inbee Park after the second round of the HSBC Women's Champions.

Ciganda offset a pair of bogeys with eight birdies at Sentosa Golf Club to finish even with Park (69) at 9-under 135.

Azahara Munoz was in third place, two strokes back, after a 67 that featured six birdies against a lone bogey.

Top-ranked Lydia Ko birdied three of the last four holes en route to a 70 that put the 17-year-old in a tie for fourth with Stacy Lewis, Jenny Shin and Karrie Webb at 6-under.

Defending champion Paula Creamer was tied for 36th after a 71. Michelle Wie fired a 70 that included three bogeys, three birdies and an eagle.

Cejka leads by one

Alex Cejka birdied three of his last five holes Friday for a 5-under 67 and a one-stroke lead in the PGA Tour's wind-swept Puerto Rico Open.

Cejka birdied Nos. 5, 7 and 9 in a bogey-free round to reach 7-under 137 at Trump International-Puerto Rico. A four-time European Tour winner, the 44-year-old Czech-born German is winless on the PGA Tour.

Brandon Hagy was second. Making his third PGA Tour start, he birdied his final hole for a 67.

Argentina's Emiliano Grillo was third at 5 under after a 70.

Defending champion Chesson Hadley topped the group at 3 under after a 70.

First-round leader Mark Hubbard followed his opening 68 with a 74 to drop to 2 under.
