Italy's Alessandro Tadini hit a flawless seven-under par 62 to move into a two-shot lead in the second round of the Wales Open on Friday.
SECOND ROUND LEADERBOARD
GB&Ire unless stated
-11 Alessandro Tadini (It)
-9 David Lynn
-8 Miguel Angel Jimenez (Spa)
-7 Jean-François Lucquin (Fra),
-6 Christian Cevaer (Fra), Richard Finch, Benoit Teilleria (Fra), Francois Delamontagne (Fra), James Heath, Ian Woosnam
Tadini, who broke the newly-established course record by a shot, is on 11 under-par 127.
England's David Lynn is second after a 66, with Spain's Miguel Angel Jimenez a shot further back following a 67.
But Colin Montgomerie slumped out of the tournament with a second round six-over-par 75 to finish eight over.
Meanwhile, Ryder Cup captain Ian Woosnam continued his good run of form at Celtic Manor with a one-under-par 68 to go six under.
"I think people realise I have responsibilities to the Ryder Cup and don't expect me to play well," he added.
"I've got four months until qualification starts and I will try to play some good golf. Even when it starts I'll try to get Ryder Cup things done on Tuesday and Wednesday and then play the tournament."
Lynn was one of six players sharing the overnight lead on six under par.
The 31-year-old looked set to overhaul early second-round leader Tadini when he fired four birdies in his first seven holes.
But he could only manage a level par back nine of 34 as he chases his second European Tour title.
"Conditions were fairly tricky," Lynn said. "I got off to a good start and could have capitalised on it and found myself in the lead, especially with the back nine playing a little easier.
But the wind was making it tough and there were some funky pin positions out there."
AC Milan fan Tadini is hoping he can hang on to a half-time lead better than his side managed in the recent Champions League final.
"I watched the final on television at Wentworth and I was very disappointed of course," said the 31-year-old, for whom the winner's cheque would be almost two-and-a-half times his total career earnings to date.
"Hopefully I can do better than Milan and go on and win."
