PRO BASKETBALL—Midwest Division-leading Dallas is off to its best start ever. The Mavs won four straight last week to run their record to 25-11 and take a 4�-game lead over second-place Houston. Along with two easy wins over the Los Angeles Clippers, Dallas beat Portland 120-116 and stormed back from an 18-point first-period deficit to defeat Milwaukee 113-97. Almost as important as Mark Aguirre's 28.5 points per game was the play of forward Roy Tarpley, who came off the bench to average 17.5 points and 12.8 rebounds. In the Central Division, Atlanta's lead over second-place Detroit grew slightly, to 4� games, and the Hawks' 3-2 week gave them a 29-11 record—best in the Eastern Conference—and secured All-Star Game coaching honors for Mike Fratello. Dominique Wilkins, who averaged 33.6 points for the five games, set an Omni record for points scored in a period when he got 24 in the first 12 minutes of a 106-94 Hawk defeat of Chicago. Atlantic Division-leading Boston, after running its win streak to seven with routs at home of Golden State, Phoenix and Atlanta, visited Cleveland, where the Celtics hadn't won in their last three tries. That pattern persisted as the Cavaliers ran away in the fourth period to triumph 119-100. Improving quickly in the Atlantic was Washington, which lost to Chicago early in the week but then won three straight to go 7-2 under new coach Wes Unseld. In the Pacific Division, the pacesetting Los Angeles Lakers stumbled slightly in a midweek 115-113 loss to Denver but bounced back with a 113-112 win over New York, in which Kareem Abdul-Jabbar had 12 fourth-period points, and a 116-109 defeat of Seattle that snapped the SuperSonics' 17-game home win streak.

HOCKEY—How much does Edmonton miss Wayne Gretzky? Since losing their star center to a knee injury on Dec. 30, the Oilers have gone 4-4-4, and in four games last week earned only one point, which came when rookie Kelly Buchberger's first NHL goal gave them a 4-4 tie with Quebec. Otherwise, Edmonton lost to Montreal 6-4, to Philadelphia 3-1 and to the Islanders 3-2. What had been a one-point Smythe Division lead for Edmonton at the beginning of the week was a one-point deficit at its end, as Calgary went 1-1-1 to reclaim first place. Detroit's Norris Division lead grew to nine points as the Red Wings won a pair of squeakers and then came from behind to pull out a tie. Detroit beat Toronto 4-3 and New Jersey 3-2 when Brent Ashton's 40-foot slap shot 3:37 into overtime beat Devils goalie Bob Sauve. The Wings then drew 4-4 with the Flames and lost 2-1 to Hartford. Neither Boston nor Montreal, each of which had the Adams Division lead at some time during the week, played as if it cared to put any daylight between itself and its rival. The Bruins, who began the week with a one-point lead, sandwiched a 6-1 win over Minnesota between losses to Buffalo, 5-3, and Philadelphia, 6-4. The Canadiens, after defeating Edmonton to take first place, fell 4-1 to St. Louis and 4-3 to Pittsburgh and then climbed back into first with a 5-3 win over Quebec. The Flyers extended their Patrick Division lead to five points. After its win over Edmonton, Philly traveled to Boston Garden, where it scored six unanswered goals against the Bruins and held on to triumph 6-4. The Flyers finished the week with a 5-3 loss to Minnesota. Pittsburgh won three straight games, during which Mario Lemieux had seven points—two goals, five assists—to push his NHL-leading total to 102.
