Mike Bibby scored 31 points, including a clinching jumper with 11.7 seconds remaining, and the Sacramento Kings handed the Atlanta Hawks their sixth straight loss, 100-97 Friday night.
The Hawks (5-26) have lost 11 of 12. Only New Orleans has a worse record.
"I know when he takes a shot late in the game, he's going to make it," said Chris Webber, who added 28 points for the Kings. "Even if he's missed 15 in a row."
Webber bounced back from a 6-of-21 shooting performance in a loss to Toronto. He made his first six shots and finished 13-of-22 from the field.
Al Harrington led the Hawks with 22 points. Walker added 21 but he had another dismal night at the foul line, missing all five of his attempts to drop his season percentage below 52 percent.
Josh Smith scored 16 points for Atlanta -- 12 of them coming on six dunks that kept bringing the fans to their feet.
Pistons 110, Celtics 104
In Boston, Richard Hamilton scored 25 points, recovering from a dubious record-setting night by making two key baskets down the stretch to help Detroit beat Boston.
Chauncey Billups scored 22 for the defending NBA champions, who lost to Memphis 101-79 on Thursday night as Hamilton went 0-for-10 from the field and 14-for-14 from the line to become the first player in NBA history to lead his team in scoring without making a single basket.
Paul Pierce scored 22 and Ricky Davis added 19 for the Celtics, who shot 59 percent from the floor compared to Detroit's 49 percent. Boston had won five consecutive home games.
Nets 82, Warriors 72
In East Rutherford, New Jersey, Vince Carter scored 22 points, Richard Jefferson added 20 and New Jersey bounced back from two bad road losses to beat Golden State.
Jason Kidd added 13 points, 13 rebounds and nine assists as the Nets sent the Warriors to their fourth straight loss.
Mike Dunleavy, Calbert Cheaney and Mickael Pietrus scored 12 points apiece for the Warriors, who played their fourth straight game without starting shooting guard Jason Richardson (sprained left ankle). Cliff Robinson added 11 points, five rebounds and three blocks.
Magic 111, Bobcats 91
In Orlando, Florida, Hedo Turkoglu scored 22 points, fellow reserve Pat Garrity added 16 in Orlando's victory over Charlotte.
Grant Hill scored 16 points and Tony Battie added 13 on 6-for-6 shooting for the Magic, who on Nov. 6 became the first team to lose to the Bobcats. Steve Francis had 10 points and tied his season high with 13 assists.
In a matchup of the top two picks in last year's draft, Charlotte's Emeka Okafor had 15 points and six rebounds and Orlando's Dwight Howard's 10 and 12.
Primoz Brezec scored 18 points for the Bobcats on 8-of-11 shooting. Kareem Rush had 15, while Brevin Knight had 10 assists and seven points
Bucks 107, Raptors 105, OT
In Toronto, Desmond Mason had 23 points and Michael Redd scored 10 of his 15 points in the fourth quarter as Milwaukee beat Toronto in overtime.
Jalen Rose sent the game overtime with a driving layup at the buzzer, but Mason had five points in the extra period and Toronto's Morris Peterson missed a potential tying jumper with one second left.
Maurice Williams added 22 points for the Bucks, who have won just three of their 15 road games.
Rose and Eric Williams each had 21 points for the Raptors, who are 4-6 since trading Vince Carter to New Jersey on Dec. 17.
