PRO BASKETBALL—NBA: Washington was in first place in the Central throughout the week. The Bullets defeated Philadelphia 128-111 and Houston 113-106, Phil Chenier scoring 30 points in their 11th win in 13 starts. After splitting a home-and-home series with the Knicks, the Bullets were two games ahead of Cleveland. The dogged Cavaliers lost two of three in the West but hung close by overcoming a 19-point deficit to beat Portland 113-100. Milwaukee's second-year guard, Brian Winters, scored 28 points, 12 of them in overtime, to propel the Bucks to a 111-109 victory over New Orleans that left them 2� games ahead of Detroit in the Midwest. Philadelphia downed Boston 123-110, with Doug Collins tallying a season-high 38 points and Fred Carter adding 31. The win temporarily hoisted the 76ers past Buffalo into second place in the Atlantic, six games behind the Celtics. The Braves regained second, downing Philadelphia 105-99, as the Buffalo defense held George McGinnis to just four field goals. Golden State still has things its own way in the Pacific, although Los Angeles beat the Warriors for the first time this season, 106-99, replacing Seattle in second place. Kareem Abdul-Jabbar scored 35 points and teammate Gail Goodrich popped in 14 of his 36 points in the fourth quarter.
ABA: No longer need anybody be surprised to learn that Denver's David Thompson has shot his way into the record book. In the Nuggets' third win this week, a 137-125 defeat of St. Louis, the rookie wasted little time in adding his name to yet another page. He tied a league record with 21 first-quarter points, sinking each of his first eight field-goal attempts and making five of seven free throws. Thompson missed the hoop for the first time on shot No. 11 and finished with 31 points. League high-scorer Julius Erving tallied 36 points and had 11 rebounds as the Nets beat Virginia 127-108. The Nets' victory kept them two games in front of third-place San Antonio. The Spurs defeated Indiana 124-114 in overtime, with George Gervin scoring 37, including 17 field goals, and James Silas netting 30, including the two free throws that sent the game into the extra period. Indiana, clinging to the fifth and final playoff berth, ended a four-game losing streak with a 107-97 pasting of San Antonio as Len Elmore pulled down 17 rebounds, and Billy Knight, the league's No. 2 scorer, tallied 31 points. Kentucky held on to fourth place, edging the Pacers 113-109 as the league's No. 4 scorer, Artis Gil-more, netted 28 points.

HOCKEY—NHL: Islander rookie Bryan Trottier surpassed league records for points and assists by a rookie in a 3-3 tie with Vancouver. Two assists gave him 79 season points, bettering Marcel Dionne's 1971-72 record by two, and his total of 54 assists topped teammate Jude Drouin's 1970-71 season mark by the same amount. In an earlier 2-1 victory over California, fellow rookie Glenn Resch lowered his goals-against average to 1.98, the league's best. The Islanders wrapped up a playoff spot with a 6-3 defeat of Washington. Patrick leader Philadelphia's No. 1 line of Bill Barber (97 points), Bobby Clarke (99) and Reggie Leach (71) became the fourth best ever with 118 goals this season. Pittsburgh pulled into a second-place tie with Los Angeles in the Norris, light years behind Montreal, when Goalie Michel Piasse recorded the Penguins' first shutout of the season, a 5-0 blanking of Minnesota. Two California rookies, Dennis Maruk and Fred Ahern, led the Seals to a 4-3 defeat of Adams leader Boston—the Bruins' first loss in their last 12 games. Vancouver trailed Chicago by two points in the Smythe, as the Black Hawks lost their fourth in a row, 7-4 to St. Louis and the Canucks beat Minnesota 4-3.
WHA: Veterans like Bobby Hull, Gordie Howe and Frank Mahovlich go on and on and on in the junior league. Mahovlich, left wing for the Toronto Toros, scored twice in a 5-2 defeat of Quebec to raise his career goal total to 601. He only trails Howe of Houston (869) and Hull of Winnipeg (822). The Toros have met with less success than Mahovlich this season, having virtually eliminated themselves from playoff consideration by compiling the league's worst record, 18-40-5. (Only two of the 12 still-functioning teams will be eliminated from postseason play.) In the East, with 14 games to go, Cincinnati and New England exchanged the lead, with Cleveland maintaining a slim edge over last-place Indianapolis. All three surviving teams in the Western Division should make it to the playoffs. Houston moved ahead of Phoenix by 12 points as Mark Howe netted three third-period goals, turning a 3-3 tie into a 6-3 win over the Roadrunners.
