American Luke Guthrie remained the man to catch after the second round of the BMW Masters, extending his lead to four shots on a rollercoaster day at Lake Malaren.
Guthrie added a 71 to his opening 65 to finish eight under par in Shanghai, with English duo Simon Dyson and Paul Casey, Scottish pair Scott Jamieson and Craig Lee, Argentina’s Ricardo Gonzalez and Thailand’s Thongchai Jaidee all sharing second place on four under. Rory McIlroy carded a level par 72 and trails Guthrie by seven shots.
“It was a testing day. I had a couple of holes where I didn’t get it up-and-down like I
should have and I didn’t take advantage of some of
the opportunities I gave myself,” said the world number six.
“But yeah, I mean, it could have been a few better. But I still haven’t done myself much damage and hopefully the weather clears up a little bit by the weekend and we can start making a few more birdies.”
Graeme McDowell slipped back to tied for 19th after a second round 74 left him eight shots behind the leader Guthrie.
Race to Dubai leader Henrik Stenson is two over after struggling to a 74.
Stenson has a lead of 425,573 euros (£362,660) Graeme McDowell on the money list.
