Adam Scott moved into a share of the lead with compatriot Richard Green as The Barclays Scottish Open resumed at Loch Lomond.
The 28 year old Australian birdied the 415 yard 12th to improve to six under par at the start of his second round and joined overnight leader Green - who was amongst the late starters - on seven under with another birdie at the long par four 16th.
And Marcus Fraser made it a trio of Australians at the head of the field with four birdies through his first ten holes to also reach seven under.
Ireland’s Paul McGinley went on something of a rollercoaster ride in his round. He bogeyed the short fifth, got back in the joint lead with a birdie on the next, but then dropped another stroke at the seventh.
Darren Clarke, playing with Scott, climbed to five under thanks to three birdies in a row as well - in his case from the 11th - while Ernie Els and fellow South African Retief Goosen both moved to four under.
Last week’s winner Martin Kaymer and yet another Australian - Rod Pampling - were also on the move as they advanced to six under on an increasingly congested leaderboard.
Three players on six under were yet to tee off their second round - Spain's Gonzalo Fernandez-Castaño, England’s Graeme Storm and Scotland’s Martin Laird.
