PRO BASKETBALL—As play resumed after the All-Star break, the once-hapless New York Knicks stretched their surge to 11 wins in their last 15 games with victories over Cleveland (108-92) and Denver (124-115) before losing to Atlantic Division-leading Philadelphia 104-89 (page 14). Much of the credit belonged to resurgent Center Bill Cartwright, who has averaged 20.4 points a game during the Knicks' upturn (he'd been scoring at a 13.1 clip before that), Guard Paul Westphal (14.3 and 8.3) and Power Forward Truck Robinson (15.9 and 7.5). With Westphal and new acquisition Rory Sparrow sharing the point, odd man out was Edmond Sherod, who'd been averaging 28.8 minutes a game, third on the team, before the break, but got to play only 21 minutes in the three games last week. Que Sherod, Sherod. Bill Walton, once a Trail Blazer now a Clipper, played his first game in Portland in five years. "I recognized a lot of old faces and a lot of old voices," he said. He showed the 12,666 in attendance a lot of old moves—he had 15 points and nine rebounds in 35 minutes—but his old team dumped his new one 115-106. San Diego, last in the Pacific Division, fell 22� games behind pace-setting Los Angeles. Things were buzzing in the Midwest, where Dallas' Pat Cummings had to be rushed to a hospital after suffering an allergic reaction to some bee pollen he'd taken as an energy booster. But it's Houston that may be about to be stung. With the NBA's worst record (10-44, 22� games in back of division-leading San Antonio) and possessing the first pick of Cleveland, which had the poorest mark in the Eastern Conference, the Rockets until recently seemed assured of having the No. 1 choice in the draft—to be used, no doubt, to obtain Virginia's Ralph Sampson. But the Cavaliers (13-41 and 23 games behind Central Division leader Milwaukee) are slowly gaining on the faltering Pacers (16-38), which means Sampson's destination may be decided by the toss of a coin. That's assuming, of course, the financially troubled Pacers are still around when the flip is conducted in June.

HOCKEY—Buffalo Center Gil Perrault's long, low slap shot 12 minutes into the game was the beginning of the end of Boston Goalie Pete Peeters' try for NHL immortality. The puck flew over Peeters' outstretched stick and into the Bruin net. Two more followed, and the Sabres beat the Adams Division leaders 3-1. It was Peeters' first loss in 32 games, one shy of Gerry Cheevers' NHL record. His Montreal counterpart, Rick Walmsley, kicked out 31 of 33 shots as the Canadiens defeated Smythe Division-leading Edmonton 4-2. Naturally, the two shots that made it through were by Wayne Gretzky. Rookie Goalkeeper Bob Froese of Philadelphia, first in the Patrick Division, extended his unbeaten string to 13 games with a 3-0 victory over New Jersey.
