A Roundup of the Week Feb. 1-7

PRO BASKETBALL—In a week abbreviated by the NBA All-Star break, the division front-runners maintained their positions, though the four-day midseason hiatus may have been the only break Dallas got. On Monday the Mavericks were beaten 108-103 by woeful New Jersey, which thereby broke its 26-game losing streak on the road. Three days later Dallas fell to another last-place team, Sacramento, 118-101. Between those defeats, the Mavericks lost another, 115-105, to Midwest Division runner-up Denver, which moved to within two games of Dallas. Events took a more predictable turn in the Atlantic Division, where first-place Boston extended its home winning streak over Indiana to 23 games with a 118-103 rout. The Celts were beaten the next night in Milwaukee, 111-101. In the Central Division, pacesetting Atlanta lost its fourth straight, falling to Portland 121-118. Hawks point guard Doc Rivers then provided much-needed relief in Seattle, getting a career-high 37 points in a 119-109 victory over the Sonics. In the Pacific Division, Magic Johnson sparked the Los Angeles Lakers to a 110-101 victory over Chicago, and two days later he had his sixth triple double of the season—18 points, 10 rebounds, 11 assists—in a 117-86 clipping of the other Los Angeles team. In Sunday's All-Star Game, Michael Jordan scored 40 points to earn MVP honors and pace the East to a 138-133 win over the West.

The Red Wings' win over Calgary extended the Smythe Division-leading Flames' losing skid to three games. Calgary also fell to New Jersey 5-4 and to Winnipeg, 9-0. The latter game was marred by 128 penalty minutes. Philadelphia remained atop the Patrick Divison with wins over Toronto, 6-1, and St. Louis, 4-2. The defeat snapped the Blues' club-record seven-game winning streak. In the Adams Division, Boston went 4 for 4 with victories over Chicago, 5-3, Montreal, 7-3, Quebec, 3-2, and New Jersey, 6-3, to reclaim first place from the Canadiens. Marcel Dionne of the New York Rangers got his 717th career goal in a 6-3 win over Pittsburgh; it tied him with Phil Esposito for second on the NHL alltime scoring list.
