Glenn Anderson scored two goals, Wayne Gretzky reached another National Hockey League milestone with his 600th assist, and the Edmonton Oilers won for the first time ever in Boston Garden, beating the Bruins, 4-2, last night for their fifth straight victory.

After Charlie Simmer pulled Boston into a 1-1 tie with a power play goal in the opening minutes of the second period, Gretzky assisted on Anderson's 15th and 16th goals as Edmonton went ahead to stay. The assists were Gretzky's 41st and 42nd of the season. He has 66 points.

The Bruins outshot Edmonton, 43-27, but goalie Grant Fuhr frustrated the Boston shooters as the Oilers earned their first victory at Boston Garden since joining the NHL six years ago. The Bruins had been 7-0-1 against Edmonton at home.

"I guess a $35 incentive worked," Oilers Coach Glen Sather said with a laugh. "I told the team that if we won, I'd pay for the beer and sandwiches on the bus ride to Hartford (Conn.) and if we lost they'd pay for them."

Sather said the team would have beer and submarine sandwiches on the two-hour bus ride to Hartford for a game Friday night. How Sather came up with the $35 figure was not known, and no one questioned his mathematics.

Boston had an apparent goal disallowed late in the second period when referee Bob Myers ruled a whistle had stopped play. The Bruins also outplayed Edmonton in the third period before Dave Hunter scored his fifth goal, on a 40-foot wrist shot with 3 1/2 minutes remaining.

"It's depressing not to win a hockey game like that," Boston Coach Gerry Cheevers said. "There were two good hockey teams knocking heads out there. They didn't overpower us, they didn't beat us in the hitting department. They just beat us."
