Denmark's Thomas Bjorn is joint leader of the European Open at the K Club in Straffan after a second-round 69.
GB & Ire unless stated
-5 T Bjorn (Den), J Donaldson
-4 J Lomas, B Rumford (Aus), A Hansen (Den), G Storm, D Clarke
-3 R Muntz (Ned), F Delamontagne (Fra), R Goosen (SA), C Schwartzel (SA), M Brier (Aut)
+2: M Campbell (NZ)
+3: L Westwood
+4: C Montgomerie
Bjorn is tied with Wales' Jamie Donaldson (70) and one shot ahead of a group including Ulsterman Darren Clarke (71) and England's Jonathan Lomas (72).
Overnight leader Trevor Immelman is three shots off the lead after a 76, one shot behind fellow South African Retief Goosen who shot a 74.
Lee Westwood and US Open Champion Michael Campbell just made the cut.
England's Westwood carded a 74 for three over overall while Campbell was one shot better after a 72.
Scotland's Colin Montgomerie made the cut, which came at five over, by one stroke.
Bjorn, 34, walked out of the event after just six holes last year but has fought back to be in good form ahead of The Open in a fortnight's time.
Bjorn said: "There are a lot of guys that go through stuff like that.
"You can try to stand on the driving range and battle your way through or you can go home and get a bit of perspective on things.
"I chose the second one and I think that was the best thing I ever did. The one thing I take from the experience is that most good players will bounce back from situations like that."
Those to miss out on the weekend include Ryder Cup stars Ian Poulter, Paul Casey, Paul McGinley and Padraig Harrington.
European skipper Ian Woosnam will also be going home early after a second-round 72 failed to make up for a miserable 78 on Thursday.
Harrington, who endured an opening-day 79, slumped to his worst 36-hole score in Europe since 1996.
He suffered a disappointing second round of 74 to finish with a nine-over par total.
"The damage was done on Thursday," said the world number eight, who last week claimed his second US Tour victory of the season at the Barclays Classic.
"I certainly need a weekend off and a lot of the 12 days before I tee it up in the Open will be based on rest.
"It's a question of really getting my mind around things so that I'm sharp enough and fresh enough. I'm happy with how I'm swinging the club."
