Swede Peter Hedblom chipped in twice and Australian Matthew Millar finished with a 100-footer as they took over at the top from Lee Westwood in the Andalucian Open at Aloha on Friday.
Defending champion Westwood, having opened with a seven-under-par 65, followed up with a 73, three-putting the last from only six feet.
At the same hole 30 minutes later, Millar carved his drive into the trees, came up short of the green and then sank his pitch for a three and a 69.
Hedblom, meanwhile, struggled with a heavy cold but as well as making a 25-foot eagle putt on the long fifth, holed from off the green at both the seventh and 13th to be round in 67.
The 38-year-old, who earlier this month was a fraction of an inch away from a successful defence of the Malaysian Open, reached halfway alongside Millar on the eight-under-par total of 136.
They lead by one from English pair Richard Dinwiddie and David Lynn and Frenchman Thomas Levet.
Westwood dropped to joint sixth on six under, while English amateur champion Danny Willett fell away to three under with a disappointing 75 after starting his first European Tour event with a brilliant 66.
"The greens are a bit trickier in the afternoon - they get a bit iffy," said Westwood. "I probably deserved better than 73, but you have days like that.
"It would have been nice to two-putt the last from six feet, but what can you do?
"It jumped straight left on me. The second putt he missed was from under two feet."
