Charl Schwartzel's magnificent recent form continued with an eight under par 64 in the second round of the Alfred Dunhill Championship in South Africa.
Fifth, third, second and first in his last four starts, the 2011 Masters Tournament champion moved level with France's Grégory Bourdy on 13 under par at the halfway stage at Leopard Creek.
Winner in Thailand by an incredible 11 stroke margin on Sunday, the 28 year old South African has yet to drop a stroke and picked up an eagle and six birdies on a course where he has previously had a victory and four runner-up finishes.
Bourdy was not to be outdone, however, and by adding a 65 to his pacesetting opening 66 kept alive his hopes of a fourth European Tour title.
Highlight of his round was pitching in for an eagle two at the 319 yard sixth.
Bourdy had just holed from 25 feet on the previous green and he sank another at the eighth as he and Schwartzel moved clear of the chasing pack.
Schwartzel said: "It was a very solid round. I made hardly any mistakes and got away with the odd bad shot.
"It's out there. If you are playing par fives well and hitting the fairways you can hit some good shots into the greens.
"I've not driven as well as I did a couple of weeks ago, but I'm hitting good iron shots and felling good with the putter."
His fellow South African Darren Fichardt was four strokes back in third place following a 68 and as the afternoon starters teed off again there was a further three shot gap to a group which included last week's Nelson Mandela Championship presented by ISPS Handa winner Scott Jamieson.
“I'm feeling great and I played two good rounds,” said the 30 year old Bourdy. “I had many birdie opportunities again today, especially on the first holes.
“My game was again solid, and I made just one bogey today, so it was a great round again.
“It's going to be an exciting weekend. Charl (Schwartzel) is a great player, one of the best in the world. In South Africa it's always nice to play with some of the top players in the world on Saturday and Sunday. I like these guys, so it should be a great time.
“It's tough all week - you have to do the job over four rounds and that is difficult. When you play well you have to see how you are on Sunday. Tomorrow I will try to do the same - shot by shot, play my game. I think the top players will do the same.”
