In-form Ernie Els takes a dip into the lead at Bay Hill

Ernie Els got his feet wet on Friday to continue his run of impressive pre-Masters form by grabbing a share of the second round lead at the Arnold Palmer Invitational.

The South African's solid three under-par round of 69 at Bay Hill was enough to move him in a tie for the lead on seven-under with American trio DJ Trahan, Ben Curtis and Davis Love III.

It could have been very different for Els, who earlier this month claimed his first tour win in two years with victory at the WGC-CA Championship at Doral, if he had not made a remarkable recovery from a water hazard on the sixth.

Having just three-putted on the fifth, for his second bogey of the round, Els drove into water to the left of the fairway on the sixth.

"I hit it really solid but I pulled it. I almost made it but it pitched just on the bank and rolled back into the water," said Els, who then took his shoes and socks off to play out of the shallow water.

"That was a big break because if the ball was another yard left it would have been into the deep end," he said of the ball's position in the hazard.

"But I could play it and I chipped out of the water, played a four iron just right of the green and I was up and down for par.

"I was a yard away from probably not being in the tournament anymore because that would have been a sure double-bogey and I would be back to even-par and in a battle to make the cut."

Els went on to make six birdies and a bogey in the rest of his round to set up what he called "a very interesting weekend".

The leading quartet are just a stroke ahead of Els' compatriot Retief Goosen, world number three Phil Mickelson and American Kevin Na.
