Padraig Harrington became the eighth player to seal his place in Europe's Ryder Cup team, but fellow Dubliner Paul McGinley faces an anxious wait.
Harrington is certain of a place at the K Club in three weeks
Harrington cannot be overtaken in the standings after McGinley missed the cut at the BMW International in Germany.
McGinley, 10th in the race, must hope no-one edges past him in the rankings.
Martin Erlandsson holds the clubhouse lead in Munich on nine under, with David Howell one of four players on eight under.
Alongside McGinley, Jose Maria Olazabal, who is not playing in Munich, is the player most in danger of losing his Ryder Cup place.
It will be extraordinary if I don't make it
Paul Broadhurst would overtake him with a top three finish but lies down the field on one under.
A top two finish would put Johan Edfors (-2) above Olazabal, while Thomas Bjorn (-4) would have to win the title.
John Bickerton could also have overtaken the pair but missed the cut on level par.
McGinley, who holed the winning putt in the 2002 Ryder Cup, shot a 72 to finish three over.
"It will be extraordinary if I don't make it," said McGinley.
"It looks like there's tension, but honestly I don't feel it. I'm just not playing well.
"Two years ago there was a lot more pressure (it went to the final hole before he sealed his spot) and I came through it. I've lost confidence and I've got to sort it out."
The game's definitely beating him up at the moment
Padraig Harrington on Paul McGinley's struggles
Harrington, meanwhile, moved to five under after a second round of 70.
He joins David Howell, Paul Casey, Luke Donald, Sergio Garcia, Colin Montgomerie and uncapped pair Henrik Stenson and Robert Karlsson in Ian Woosnam's team for the K Club from 22-24 September.
Harrington said McGinley's form would improve once the qualification process had finished.
"He is taking it a bit too much to heart - he's over-trying," he said. "He's had nine months of a noose round his neck and I think Monday will be a massive difference when it's over and he's in the side.
"A change of attitude would be far better than a change of swing. The game's definitely beating him up at the moment. Golf's winning."
Lee Westwood overcame the worst possible start to keep alive his hopes of clinching a wildcard with his first win for three years.
Westwood, suffering from suspected tonsillitis and also being monitored for fatigue, hooked his opening drive into a ditch - and then discovered his driver had a hairline crack.
The Englishman overcame the setback to card a 71, which left him five under.
