Doug Tewell took advantage of Calvin Peete's collapse with a six-under-par 65, came from six shots back and vaulted into a two-stroke lead today in the third round of the $450,000 Phoenix Open.

Tewell, a 35-year-old journeyman tourist whose only two PGA Tour victories came in 1980, had eight birdies and rallied from a double bogey with a birdie-birdie-birdie finish.

He completed three rounds over the 6,726-yard Phoenix Country Club course at 200, 13 under par.

Tewell, Tim Norris and Bob Eastwood started the third round tied for second, five shots behind Peete, the 1984 Vardon Trophy winner, who shot 65s in the first two rounds.

Today, with tears streaming down his face caused by a possible allergy attack, Peete made four bogeys -- his first of the tournament -- and had to work hard for a one-over-par 72 that left him tied for second with Morris Hatalsky at 202. Hatalsky, playing in the same group with Tewell, salvaged a 66 with a scrambling back nine.

Peete, who told tournament officials he was having difficulty with his contact lenses, wiped his eyes repeatedly during the round. He declined to be interviewed afterward and sought the services of an optometrist.

Isao Aoki of Japan moved up with a 67 in the warm sunshine and was three back at 203. Ed Fiori was next at 65 -- 205.

Lanny Wadkins, who won last week's Bob Hope Classic, was in a group at 210. PGA champion Lee Trevino and Phoenix defending champ Tom Purtzer were in a group at even-par 213.

Peete made his first two bogeys of the tournament on the third and fourth holes but bounced back with three consecutive birdies.

That rally enabled him to retain two strokes of his lead at the turn in the face of Tewell's challenging 32. They matched birdies on the 10th.

Peete, playing one hole behind Tewell, appeared to have a little breathing room when Tewell made a double bogey on the 15th, hitting into the water.

"I stepped back from the shot," Tewell said. "I couldn't pick out the pin against the gallery. When I finally located it, I just made a totally bad swing."

But Peete three-putted for bogey on the same hole moments later, then drove into trouble, hit into a bunker and bogeyed the 16th.

At the same time, Tewell made three consecutive birdies. The first two, on the 16th and 17th, came on 15-foot putts. The last one came on a little pitch and a three-foot putt.

"I didn't let the problem at 15 upset me," Tewell said. "On 16, I split the fairway and the crowd roared. That kind of pumped me up.
