A roundup of the week Feb. 19-26

BASEBALL—The Major League Players Association and club owners reached tentative agreement on a three-year contract, pending ratification by both.

PRO BASKETBALL—NBA: While the Los Angeles losing streak of four games became the longest ever under Coach Bill Sharman (page 63), Rick Barry was doing his best to help second-place Golden State gain on the Lakers in the Pacific Division. Barry has a flair for such things, like getting off a stretcher to lead the Warriors to a 111-106 victory over the Lakers. Barry bruised his back in a second-quarter fall but came back to score 12 of his 20 points in the second half. His 10 points in the last 5½ minutes against Milwaukee lifted Golden State to a 102-93 win as the Warriors outscored the Bucks 30-19 in the final period. In the Atlantic Division, Boston continued to pull away from the Knicks as New York blew a 24-point halftime advantage and a three-point lead in the final 26 seconds at Chicago. The Knicks scored just 26 points in the second half as the Bulls won 84-83 on Bob Love's rebound basket in the last eight seconds. New York recovered at home the next night with a 125-97 triumph over Buffalo to slice the Celtic lead to 3½ games. Chicago, with Love scoring five straight baskets in an 18-point spurt, kept the pressure on Milwaukee in the Midwest Division. Love hit for 30 points as the Bulls won their sixth straight, 122-100 over Phoenix. The Bucks' lead was chopped to 3½ games. In the Central Division, Archie Clark's season-high 31 points helped first-place Baltimore defeat Portland 128-110 to maintain a six-game margin over Atlanta.

ABA: Suddenly Denver, winner of six straight, was turning the Western Division into a three-team race. In the fifth win, Warren Jabali scored 28 points as the Rockets took a 115-104 victory at Carolina to cut Utah's lead to six games. Indiana remained in second place, 4½ games behind the Stars. Although Kentucky continued to pressure Carolina, the Eastern Division remained a two-team affair. Dan Issel's 35 points and Artis Gilmore's 20 rebounds helped the Colonels win at Dallas, 107-102, and pull within 3½ games of the Cougars. In a battle for the fourth-place playoff spot, Memphis drew within two games of New York with a 107-98 triumph over the slumping Nets.

GOLF—LEE TREVINO won the $52,000 first prize in the Jackie Gleason Inverrary National Airlines Classic with a 279 as three-day leader Forrest Fezler missed short putts on each of the last two holes (page 24).

HOCKEY—NHL: There continued to be rumblings in the East Division as Boston finally caught New York in the struggle for second place. Veteran John Bucyk broke a 5-5 tie with his third goal to lead the Bruins to a 7-5 victory at Los Angeles, thus creating a second-place tie with the Rangers at 85 points apiece. It was the fourth straight win for the Bruins, who trail first-place Montreal by nine points. The Canadiens, meanwhile, held fast, defeating Vancouver 7-3 as Guy Lafleur broke open a close game with a pair of goals in the second period. The Rangers figured to have an easy time at Oakland, since the Golden Seals were in the midst of a 15-game streak without a victory. But California ended its string with a 5-3 win. The last-place New York Islanders ended an eight-game losing string at the expense of Detroit, 4-2. In the West Division, first-place Chicago was shut out for the first time in a record 229 regular-season games. Pittsburgh Goalie Jim Rutherford did it as the Penguins won 2-0 on goals by Greg Polis and Jean Pronovost. Including playoffs, the Black Hawks had not been held scoreless in 263 games, the last shutout coming in March of 1970 at the hands of Boston.

WHA: Philadelphia's Danny Lawson provided third-period heroics once again, scoring the winning goal in the last two minutes as the Blazers beat Ottawa 6-5. In so doing, Lawson became the first player in the new league to score 50 goals. Cleveland, two points ahead, and New England were in a battle for first place in the East Division while the Blazers held a one-point advantage over New York for third place. The Whalers beat Alberta 4-2 and received assistance the next day from Chicago, which defeated the Crusaders 5-2 before 9,957, the largest crowd ever in Cleveland. Winnipeg retained its 11-point lead over Houston in the West.
