PGA Tour rookie Harrison Frazar's two-week stretch of outstanding play showed no sign of letting up yesterday as he fired three-under par 67 to maintain a two-stroke lead after the second round of the Colonial golf tournament.

Frazar, whose best finish before last week's tie for second at the Byron Nelson was a tie for 16th, stood at nine-under 131 for two rounds. Evidence of his soaring confidence was his disappointment with a 67 after opening with a sparkling 64.

"Things are really going my way when you don't feel good and still shoot 67," Frazar said.

Mark Calcavecchia and Kenny Perry each posted five-under 65s and were tied for second at seven-under 133, along with Jim Furyk, who carded a 67 yesterday. The absence of any serious wind left the par-70 Colonial Country Club layout without many of its usual defences.

"This is as short as I've ever seen this course play," said Calcavecchia, who opened his round with three birdies and eagled the par-4 seventh hole. "Downwind, you can hit it forever out here."

Frazar said: "If the wind doesn't blow, this course is here for the taking. I'll have to shoot eight-under for the weekend to have a chance."

While last week's showing at the Byron Nelson, where he lost to John Cook by two shots, earned him $186,000 and virtually guaranteed fully exempt status on the PGA Tour for 1999, Frazar said he had bigger fish to fry.

"People say I have enough money to get my card for next year, but I just want to win out here," he said. "I've set a lot of goals for myself and I still need to reach them."

Frazar birdied the par-four second hole, but quickly gave the stroke back with a bogey at three.

He added birdies on holes six, eight and 11, bogeyed 13 and got back to nine-under for the tournament with a birdie at the par-three 16th hole.
