Cabrera in command, Els falters

US Open champion Angel Cabrera fired an eight-under-par 63 to take a two-stroke lead in the weather-interrupted second round at the Barclays Singapore Open where Ernie Els is set to miss the cut.

American Jin Park was alone in second place on six under after shooting a one-under 70 at Sentosa Golf Club's Serapong course, while defending champion Adam Scott was a further stroke behind in the Asian Tour event after picking up four birdies on the back nine in his round of 67.

Lee Westwood (67) and Australian Gavin Flint (72) were tied for fourth on four under while world number two Phil Mickelson (72), KJ Choi (72) and Vijay Singh (70) were handily placed on two under.

But world number four Els, who was beaten by Scott in a play-off last year missed the halfway cut in the £1.9million event after shooting a five-over 76 to drop to six over for the tournament with the cut set to be five-over. Els opted to play in Singapore rather than this week's European Tour Volvo Masters.

With play suspended for 70 minutes in the afternoon due to lightning, 37 players will have to return on Saturday morning to complete their second rounds.

After opening the tournament with a level-par 71, Cabrera caught fire in his second round, shooting an impressive nine birdies.

The big-hitting Argentinian had to keep his driver in his bag for much of his opening round after the clubhead came loose from the shaft but after having it repaired overnight, he found his form in calm conditions at Sentosa.

"I really hit it well off the tee and made everything that I needed to make and that was the difference," said the world number 17, whose birdie run included a 25-foot putt at the third.

"I stroked the ball very solidly, especially on the back nine. Not really from long distance, just from makeable distances."

Westwood moved up the leaderboard after making four birdies in a solid, bogey-free round.

"I played well. I only missed one green and I had a lot of chances from 10 to 15 feet but I struggled to read the greens," said the 34-year-old. "Four under is pretty good after two rounds and I'm looking forward to the next couple of days.

"I've had six top-10s in the last seven events so that would suggest that I'm in decent form."

Els though had little to smile after eight bogeys put him in real jeopardy of missing the cut.

"It's not the way I wanted to play obviously. I felt good before the round started. I actually birdied my first hole but then after that, I just couldn't get it together," he said. "All in all, it was quite disappointing. I was hoping for better things this week but that's golf, you know.

"I'm fine. I can't give you any excuses. I wish I could but it is what it is. It's one of my worst rounds of the year and unfortunately it had to be in Singapore."

Darren Clarke fired a second successive 71 to remain on level par.
