Clippers End Hawks’ Streak at Six Games : Pro basketball: Manning scores 24 points, Jackson adds 20 as L.A. pulls within one victory of .500 mark, 111-99.

Tuesday against the Lakers was about playoff standings, possible tiebreakers and bragging rights.

Friday against the Atlanta Hawks had none of those factors, but something that was also important, and sometimes more elusive, to the Clippers.

Sustained effort.

They got that and their second consecutive victory over a possible playoff team by ending the Hawks’ six-game winning streak, 111-99, before 15,485 at the Sports Arena.

Danny Manning had 24 points for the Clippers and Mark Jackson added 20 points and 11 assists.

“We were playing a red-hot basketball team, a team that was playing great,” Jackson said. “We knew going in that it would be a tough game and that we would have to play hard. If not, we could have embarrassed ourselves. It was a great win for us.”

Added Lester Conner, who took on an expanded role and added six points and four assists without a turnover in 18 minutes off the bench: “Had we lost tonight, the effort against the Lakers would suddenly seem somewhat small, somewhat minute. But to come out and win and play as well as we did, that was great.”

The Clippers, who improved to 35-36 and can reach .500 again Sunday by beating the Dallas Mavericks at the Sports Arena, took control with a 20-5 run over the final 28 seconds of the third quarter and opening 6:26 of the fourth. That gave them a 100-85 lead with 5:34 remaining.

Manning, who had scored at least 20 points in six of the previous eight games, had 16 by halftime and the Clippers led, 57-51.

Manning scored six points as the Clippers used an 11-2 run to take a 50-43 lead. He added another basket two possessions later to give the Clippers a double-digit cushion.

The Hawks began the night winners of 12 of their 13 previous games and were 24-14 since Dominique Wilkins returned from a broken finger. The league’s No. 2 scorer had 14 at halftime and should have had more. Wilkins missed a wide-open slam dunk midway through the second quarter when the ball hit the heel of the rim and flew into the air.

His start to the third quarter, however, was historic. When Wilkins tipped in a miss by Kevin Willis 17 seconds into the quarter, Wilkins passed Larry Bird, who had 21,791 points, for 11th place on the all-time scoring list. Clipper Notes

The Clippers won’t be moving to the new Anaheim Arena, but they might become regulars in Orange County anyway. The club is considering moving training camp this fall from La Jolla to either Laguna Niguel or UC Irvine and has scheduled an exhibition at Anaheim Arena against the Golden State Warriors, part of the eight-game preseason schedule that is expected to be finalized within a week or so. The Clippers--still continuing to look most at two downtown sites and one in Burbank for a new building--considered playing three to five regular-season games in 1993-94 at Anaheim Arena, but backed off. The proposal is similar to the Boston Celtics playing a few games a season at Hartford, Conn., and the Washington Bullets going to Baltimore. “We did give it some consideration,” said Andy Roeser, the Clippers’ vice president for business affairs. “I don’t think we’ll do it next year, but I’m sure we will continue to give it some thought for the future.”

Reserve guard Jaren Jackson, sidelined since suffering a broken right ankle Jan. 12, has been cleared to play, but it appears the only way he would be activated is if someone els goes on the injured list. “In my opinion, he’s ready,” trainer Keith Jones said. “He could use a little more conditioning on the court, but he is running great, jumping great and changing direction real well.” But because Lester Conner, originally signed as a 10-day player, has been playing well as the fourth guard, Jackson’s chances to rejoin the Clippers this season don’t look good. “I don’t anticipate it,” Coach Larry Brown said, adding: “It’s just so late. . . . by the time he’s ready to go, we may have only seven or eight games left.”
