Rory open to improvement
McIlroy co-leader after a fine round gives him major boost
Rory McIlroy refused to let a last-hole bogey ruin some "ideal preparation" for the Open Championship, as Masters champion Danny Willett suffered more frustration ahead of the season's third major.
McIlroy carded a superb 66 in testing conditions at Le Golf National to claim a share of the halfway lead in the French Open as Willett's last competitive appearance before Troon ended in a second consecutive missed cut.
Six birdies in the first 14 holes had taken McIlroy into the outright lead in his first event since missing the cut in the US Open, only for the 27-year-old to drive into the water on the 18th for the second day running.
The resulting bogey left the world number four in a five-way tie for the lead on five under par, alongside Mikko Ilonen, Brandon Stone, Thongchai Jaidee and Wang Jeunghun - who won back-to-back titles in Morocco and Mauritius earlier this year.
"It's a really good day's work," said McIlroy, who revealed after his opening 71 that he had whittled 17 swing thoughts "down to about five" as he worked on eradicating some bad habits.
"I can't let a bit of a disappointing finish taint a really good day. I felt for the most part I controlled my ball well and holed some good putts. Even the ones that didn't go in looked like they were going to. I'm in a great position.
"It's a work in progress and it doesn't feel very natural at the minute - it's quite mechanical and I am concentrating a lot - but if I set up well it tends to go where I want it to."
McIlroy, who was unable to defend his Open title in 2015 after suffering an ankle injury while playing football with friends, added: "It's ideal preparation for the Open, especially with the little breeze we have had as well.
"It's great preparation to have my last two competitive rounds before the Open in contention in tricky conditions. I can't really ask for much more than that."
In contrast, Willett had earlier only been able to add a second round of 72 to his opening 75 to finish five over par and continue a disappointing run of form.
He finished third in the BMW PGA Championship at the end of May, but smashed the putter he used at Augusta in frustration during the US Open and missed the cut in the BMW International Open in Germany last week.
"The last three weeks we've putted as bad as we ever have and things haven't quite gone our way," the 28-year-old said. "When you keep shooting the worst score you can, it's a tricky game."
