A Roundup of the Week April 6-12

PRO BASKETBALL—With one week left in the regular season, all of the Eastern Conference playoff berths were locked up, but one still remained unclaimed in the Western. In the Pacific Division, Seattle missed two chances to advance, with losses to Phoenix, 127-125 in OT, and Portland, 121-115, but finally clinched when the Suns lost 119-104 to the Lakers. Phoenix kept alive its hopes of seeing playoff action with victories over Dallas, the Sonics, the Trail Blazers and San Antonio to go seven straight but still trailed Midwest contender Denver by two games in the race for the last spot. The Pacific Division-champion Lakers clinched a home-court advantage throughout the playoffs with a 135-112 win over the Clippers, then beat them again 118-100 to complete a six-game season sweep of their local rival. The Lakers finished the week with a 131-121 defeat of San Antonio and the win over Phoenix to run their victory streak to 10 games. Midwest titlist Dallas dropped two games but regained its form by beating Golden State 125-100 before thrashing the Clippers 129-100 to sweep their five-game season series. Atlanta's wins over Cleveland, Philadelphia, Detroit and New Jersey earned the Hawks the Central Division championship and ended their battle for the title with the Pistons (page 44). Detroit went 0-3 last week. Boston, the Atlantic champ, suffered its eighth road loss in nine games, 107-83 to Cleveland. The Celtics then dropped their third straight, for the first time in more than three years, 117-108 to New Jersey. Bernard King, the '85 scoring champ, rejoined the Knicks after a two-year absence with a knee injury and was held to seven points in a 132-93 mauling by Milwaukee.

HOCKEY—Los Angeles stunned Edmonton 5-2 in their Smythe Division semifinal opener, but the Oilers awakened to thrash the Kings 13-3 the next night. Wayne Gretzky amassed seven points in Game 2 to shatter the alltime playoff points record set by Jean Beliveau from 1954 to 1971. Edmonton's 13 goals also set a record for most goals in a playoff game, breaking by two the mark shared by the '85 Oilers and '44 Canadiens. In Game 3, Jari Kurri scored twice to notch his sixth goal of the series, and Mark Messier added two as the Oilers edged Los Angeles 6-5. Edmonton took a 3-1 lead in the best-of-seven series after whipping the Kings 6-3 in Game 4. Winnipeg, swept in three games by Calgary in last year's opening round, got off to a 2-0 start in the other Smythe semifinal when the Jets beat the Flames 4-2 and 3-2. Calgary then squeezed in a 3-2 victory on a Mike Bullard overtime goal before losing 4-3 to go down 3-1 in the series. In the Adams, Hartford came from behind twice to top Quebec, 3-2 in OT and 5-4, but in Game 3 Peter Stastny's hat trick and Michel Goulet's two goals lifted the Nordiques to a 5-1 victory. Goulet also scored the game-winner in Quebec's 4-1 win to even the series 2-2. Defending champion Montreal, unbeaten in 14 games, took four straight from Boston, which has now failed to eliminate the Canadiens from a playoff round in its last 18 tries. Larry Robinson had his 100th playoff point in Montreal's 6-2 win, Mats Naslund scored at 2:38 of OT in the Canadiens' 4-3 victory, Mike McPhee had a hat trick in a 5-4 Game 3 and then scored the winning goal in Montreal's 4-2 clincher. The Canadiens will next face the winner of the Hartford-Quebec series. In Norris action Gino Cavallini's goals contributed to St. Louis victories, 3-1 and 5-3, which sandwiched a 3-2 OT loss to the Leafs, who tied the series with a 2-1 win Sunday night. Detroit took four straight from Chicago in the other Norris semifinal, 3-1, 5-1, 4-3 and 3-1, and will meet either St. Louis or Toronto in the division finals. Washington went ahead 3-0 in the first 12 minutes of its Patrick series opener to edge the Islanders 4-3. The Islanders then snapped the Caps' 10-game unbeaten streak with a 3-1 victory, only to fall, 2-0 and 4-1, in Games 3 and 4. Philadelphia was shut out 3-0 by the Rangers and came back to win 8-3 and 3-0 before New York drew even with a 6-3 victory (page 82).
