VIENNA (Reuters) - Martin Wiegele led the charge for a third home win in five years at the Austrian Open on Friday when he took a share of the early first round lead with Sweden's Pelle Edberg.

Wiegele, the tour's qualifying school winner last November, bogeyed two of his last three holes but still matched Edberg's earlier seven-under after heavy rain washed out Thursday's session.

The Austrian responded by moving to nine-under with three holes left, putting himself in contention to repeat compatriot Markus Brier's victories in 2006 and 2004.

"I blocked myself out on the bogeys," Wiegele told reporters, "but I'm still happy with a 64.

"Everybody expects a lot from Austrian players but if you play well the spectators can definitely help."

While Wiegele raced out to rack up an eagle and seven birdies, co-leader Edberg relied on a more relaxed approach to card his nine-birdie 64.

"When the weather was bad yesterday I didn't hit a ball," the Swede said. "I played cards instead. Maybe I should do that all the time."

Italy's Emanuele Canonica is a shot behind on 65 while two players bound for next week's U.S. Open at Torrey Pines -- Dane Soren Hansen (68) and former champion Michael Campbell (69) of New Zealand -- are in the chasing pack.

"I just aimed to keep things simple," Campbell, who has missed six out of eight European Tour cuts this season, told Reuters. "I had a few bad swings early on but I'm heading in the right direction.

"My cup has been definitely full of too much technical stuff, in fact it's been overflowing."
