Calvin Peete, continuing his steady game, coasted to a seven-stroke victory yesterday for his third PGA tour victory in nine weeks, winning the B.C. Open in Endicott, N.Y.

Peete, who is having the best year for a black player in PGA history, shot a two-under-par 69 on the 6,966-yard En Joie Golf Club course and it was sufficient as his playing partners Jerry Pate and Fuzzy Zoeller bogeyed themselves out of contention.

Peete, 39, finished with a four-round total of 265 to win the $49,500 top prize in this $275,000 tournament, which is named after a comic strip written by Endicott native Johnny Hart.

Pate shot a 73 and was second; Zoeller, who started the day one shot behind Peete, shot a 76 to finish third at 273.

Craig Stadler, the tour's top money winner, shot 67 to finish fourth at 274, one shot ahead of Tom Kite and Mike Brennan.

Peete, 39, increased his 1982 earnings to $281,361. He rose to sixth on this year's money list.

After Saturday's round, in which Peete, Pate, and Zoeller scored 14 birdies and two eagles, it seemed as if all three would break the tournament record, but Peete was the only one to do so. His 265 broke the 1973 mark set by Hubert Green.

Peete was one up on Zoeller and two up on Pate when the day began, but he got a double-bogey 6 on the first hole. Zoeller got a birdie to take the lead and Pate parred. "My philosophy has always been that if you're going to mess up on a hole, let it be the first. Then you have 17 holes to recover," Peete said.

On the eighth hole, Pate birdied to take the lead. But Pate bogeyed the ninth, Zoeller double bogeyed and Peete birdied to move into the lead.

Zoeller eliminated himself with another double bogey on No. 10 that dropped him six shots off the pace.

The two-way race ended abruptly on No. 12 when Peete birdied and Pate took a double bogey.
