Hal Sutton led the PGA Tour pros on another scoring picnic at Phoenix Country Club with a second bogey-free 64 good for a two-shot lead through two rounds of the $500,000 Phoenix Open. His 14-under- par 128 matched the tour's low 36-hole total last year.

But he was not alone in tearing up the little course robbed of its natural defenses by the absence of wind. Don Pooley shot 61.

"What can I say?" asked Howard Twitty when he and Pooley finished. "I shot 63 and I got beat by two."

Pooley, winner of the 1985 Vardon Trophy for low stroke average on the tour, matched the course record with the lowest score on the circuit since the 1984 Walt Disney World Open.

After an opening 74, he was at 135. Twitty reached the tournament halfway point at 130, second by two strokes over a group at 132.

Hubert Green, first-round leader at 63, went 11 shots higher. His 74 gave him a 137 total. Tom Watson, even par, and Lanny Wadkins missed the cut. Jack Nicklaus made it on the nose, 69 -- 141 . . .

Jo Ann Washam, who said she recently considered retiring from the LPGA circuit, shot 67 to go six under par at 138 and lead by one after the second round of the $200,000 Mazda Classic, leading off the 1986 tour in Boca Raton, Fla.

"I didn't have enough guts to stay out," Washam said.
