Oosthuizen SA's lone ranger at BMW Championship

Woods, McIlroy share lead for first time on PGA Tour

After 36 holes, Woods sits five shots back of the leader. "I have to make birdies and try and keep pace and this golf course is playing soft and getable, and tomorrow will be the same thing".

Woods is off and running this week at the BMW Championship, shooting a six-under 29 during his first round today.

Woods meanwhile also struggled to find consistency in his second round, three birdies cancelled out by three bogeys to leave the American on even par for his round and eight-under par for the tournament heading into the weekend.

Eventually, there was going to be a day when Tiger Woods hit his fairways, was dialed in with his irons and holed the mid-length putts necessary to shoot a low-low round.

Northern Ireland's McIlroy briefly threatened to dislodge Woods before equalling the American's score. The switch paid off from his very first hole of the day-the 10th, as Woods teed off with Rickie Fowler and Jordan Spieth off the back nine- when Woods poured a 20-footer for birdie right in the center. They were joined at 10-under by Alex Noren, whose 66 Friday ended with a dramatic chip-in eagle at No. 9, his 18th hole.

They had a one-shot lead over Xander Schauffele. Kevin Na went low at 8-under for the day, matching Woods' and McIlroy's Thursday scores after carding an even-par 70 on Day 1.

The South African retained his position in the FedEx Cup standings, as he entered in the Dell Technologies Championship placed 69th.

It was the low round of the season for Woods, two shots under his closing 64 at last month's PGA Championship, and his lowest round in any PGA event since a 61 in the second round of the 2013 WGC Bridgestone Invitational - his most recent triumph.

Oosthuizen is now on 729 points - 2 888 points behind FedEx Cup leader DeChambeau.
