Lee Westwood questioned the structure of Europe’s Ryder Cup qualifying system as captain Pádraig Harrington looked set to face a selection headache at the BMW PGA Championship.
Thailand's Kiradech Aphibarnrat added a 68 to his opening 64 at Wentworth to post a halfway total of 12 under par and lead by one from England's Laurie Canter, with Adam Scott on 10 under and Justin Rose another stroke back.
But it was the constantly fluctuating battle to make the team for Whistling Straits which continued to dominate the agenda at a final qualifying event in which Harrington’s accountancy qualifications were set to prove very useful.
Westwood and Shane Lowry's places are under serious threat from Austria's Bernd Wiesberger, who would overtake Rory McIlroy in the European points list with a top-50 finish or better.
That would mean McIlroy qualified via the world points list instead of Lowry, who in turn could knock Westwood out with a top-eight finish or better, depending on Westwood’s result.
Whoever missed out would join the likes of Ian Poulter – who missed the halfway cut – Sergio Garcia and Rose in vying for one of Harrington’s three wild cards on Sunday evening, although Rose can still qualify automatically with a win.
Wiesberger had been three over par after six holes of his first round, but finished birdie, eagle and added a superb 67 on Friday to end the day inside the top 20 on six under, two shots behind Lowry.
Westwood was in danger of missing the cut when he covered the front nine in 37 to fall back to level par, but made four birdies on the back nine to record a second-successive 70.
“I’m here to try and win the BMW PGA Championship and Sunday night, if you’re in the team, then you start thinking about the Ryder Cup,” Westwood said.
“There’s so many variables as well with the way we’ve set up the qualification this time around. This tournament is heavily loaded compared to everything else we’ve done and I think it’s something to maybe look at in the future.
“You can see how players are reacting to it out on the golf course. You know there’s people right in there and they are shooting scores where clearly they have got other things on their mind.
"I've played with Shane, he's managed to block everything out well and play well and Shane Lowry is the kind of player that you want on your Ryder Cup team. I'm pleased to see him play well."
Lowry echoed Westwood’s sentiments after a 66 which left him four shots off the lead, adding: “There’s almost too many points available, especially for someone like me who is in the team.
“It is what it is. We’ve known it for a couple of years. I’m just out there to do a job. I’m out there to try to win the tournament and play as best I can and, come Sunday evening, hope I’m on the team automatically.
“If I’m not, I hope I get a pick. I feel pretty laid back about it. I’m not anxious about the whole thing.
“I feel like I’ve played really well over the last while and consistently well and I feel like I’ve put my hand up. It’s up to Paddy what he wants to do on Sunday evening.”
Harrington will have the weekend off to consider his wildcard picks after he carded a two-over 74 to finish on two over.
Graeme McDowell showed a welcome return to form with a three-under 69 to move to four under and well inside the cut mark.
Cormac Sharvin completed his first round 76 in the morning before a battling three-under 69 left him on one over and outside the cut mark, while Jonathan Caldwell also missed out after carding a one-over 73 in the afternoon to finish on level par.
