A roundup of the week Jan. 6-12

PRO BASKETBALL—If you want to beat the Midwest Division-leading Rockets, don't play them in Houston. The Rockets have won all 20 of their home games this season, including three last week. In a 124-115 win over Golden State, Akeem Olajuwon achieved a triple-double with 26 points, 12 rebounds and 11 blocked shots. Denver, which moved past San Antonio into second place in the division, was also 3-0 while the Spurs were 1-3. In the Pacific Division, the Lakers increased their lead over Portland to nine games by winning two of three outings. Kareem Abdul-Jabbar reached the career 34,000-point plateau when he sank a free throw in the second quarter of a 124-102 win over Indiana. Portland won only one of three games—109-106 over New York. Phoenix beat Seattle 114-97 in the completion of a game that had been halted in the second quarter the night before in the first rainout in NBA history. Cause of the rainout: a hole in the roof of the Seattle Coliseum. When the water began collecting at one end of the floor, fans started chanting "Half court. Half court." Later in the week Seattle handed the Lakers their sixth loss, 105-99, on the strength of rookie Xavier McDaniel's 36 points. Milwaukee stayed on top of the Central Division by winning two of three games. Atlanta continued to play well, winning its fifth straight, 110-99 over Detroit. The reeling Pistons won only one of three. In the Atlantic Division, Boston's lead over hot Philadelphia was reduced to four games as the Celtics lost to Detroit 113-109 before defeating Cleveland 126-95 and Atlanta 115-108. The Sixers were 4-0. In a 116-114 win over the Clippers, Moses Malone scored 31 points, 17 of them from the foul line, and Charles Barkley had 29 points and 16 rebounds. New Jersey, third in the division, won two of three games. The Nets snapped Milwaukee's seven-game winning streak with a 106-99 victory.

HOCKEY—The Quebec Nordiques strengthened their hold on the Adams Division lead by taking all three of their games, stretching their winning streak to seven. Their 5-3 victory over Edmonton was coach Michel Bergeron's 200th win. Still, only nine points separate the Nordiques and the last place teams, Hartford and Buffalo, in the NHL's tightest division. The second-place Canadiens were 2-2. Montreal's Kjell Dahlin, the NHL's highest-scoring rookie, netted a hat trick and an assist to lead the Canadiens past St. Louis 9-2. In the Smythe Division, first-place Edmonton lost two games before beating Montreal 6-3. Second-place Calgary, also 1-2 for the week, snapped a club-record 11-game losing streak with a 5-4 overtime victory over Vancouver as center Jim Peplinski scored 13 seconds into OT Los Angeles's prolific Marcel Dionne got his 900th assist and his 650th goal in a 4-4 tie against St. Louis. Dionne trails only Gordie Howe (801) and Phil Esposito (717) on the NHL's career goal list. Philadelphia increased its Patrick Division lead to 10 points by winning its three games. Rookie goal-tender Darren Jensen had his first NHL shutout, 4-0 over second-place Washington. The Capitals won just once in three games, beating lowly Detroit 4-3. New York Islander goalie Kelly Hrudey stopped 27 shots in a 9-0 drubbing of Pittsburgh. It was the Islanders' first shutout this season. In an 8-2 win over Detroit, islander center Bryan Trottier scored his 400th career goal, and winger John Tonelli his 200th. In the Norris Division, the Chicago Black Hawks maintained a two-point lead over St. Louis by winning two of three games. The Blues won only one of five. Their 7-2 defeat of Boston was their first win over the Bruins in more than four years.

HORSE RACING—PHONE TRICK ($2.80), Laffit Pincay Jr. up, beat Temerity Prince by 4½ lengths to win $78,200 and the San Carlos Handicap at Santa Anita. The 4-year-old ran the seven-furlong course in 1:20[4/5].

INDOOR SOCCER—In the MISL's Eastern Division, Baltimore moved into a first-place tie with Minnesota by beating Wichita 6-3 and Chicago 3-0 while the Strikers were losing to Dallas 8-1. Dallas's Tatu scored five goals in that game, giving him 45 points for the season. Tatu was one point behind the league's scoring leader, San Diego's Steve Zungul, whose team increased its Western Division lead to two games over Wichita. The Sockers beat Tacoma 8-2 and St. Louis 10-7, with Zungul scoring five points in each game.
