MIAMI, US - AUSTRALIAN Geoff Ogilvy held off the challenge of world number one Tiger Woods to lead by a shot after the second round of the WGC-CA Championships Thursday.

Ogilvy, the 2006 US Open champion, followed his seven-under 65 on Thursday with a bogey-free five-under 67 to stand at 12-under overall.

Woods, looking once again in top form, fired two eagles in his round of 66 - the best of the day - and finished with a putt of more than 23 feet for a birdie on the ninth hole.

'"I was trying to make sure that I didn't drop any shots like I did on Thursday. You don't want to end a good round dropping a shot,' said the American.

Looking for his 10th win in 11 tournaments, Woods eagled the par-five 12th - chipping in from the bunker -and the first after a 329-yard drive off the tee followed by a superb second shot that landed less than seven feet from the hole.

Winning form
He has managed to seamlessly bring his winning form from the Arnold Palmer Invitational in Orlando, where he sizzled at the weekend to win after a disappointing opening two rounds.

'I've hit the ball well this week. You basically have to with the wind blowing this hard, if you don't the wind is going to take it.

'It was nice to build on what I had done over the weekend,' he said.

Ogilvy's score was all the more impressive given that he only hit the fairway three times.

'I played a lot better on Thursday in terms of tee to green.

They weren't horrible tee shots, they would just run into the rough and stuff, it was a much trickier wind today though.

'But if I want to keep shooting good scores I am going to have to hit it better than I did today,' he said.

Another Australian, Adam Scott, was three shots behind Ogilvy having been level with Woods before bogeying the final two holes - both par fours.

Three players were tied in fourth place at six-under - Sweden's Robert Karlsson, India's Jeev M Singh and Denmark's Anders Hansen. -- REUTERS
