SAN ANTONIO -- Tim Duncan grabbed a career-high 27 rebounds and scored 21 points, and the San Antonio Spurs ended their three-game slide with a 105-90 win over the Atlanta Hawks on Wednesday night.
Antonio McDyess added 17 points for the Spurs, who won for just the second time in seven games and finally got a victory four games into their season-long, six-game homestand.
But an injury to Tony Parker might temper this win. The point guard went down in the third quarter with a sprained left ankle, the same one that caused him to miss four games earlier this season.
X-rays were negative, and the Spurs were to evaluate Thursday how much time their second-leading scorer will miss.
Joe Johnson scored 31 and Jamal Crawford had 25 points for the Hawks, whose winning streak ended at three games.
It was the first 20-20 game since 2005 for Duncan, who bested his previous career rebounding high of 25, set against Miami in 2003. Duncan shot just 5 of 20 from the field, but he had 10 offensive rebounds and hit all 11 of his fouls shots.
George Hill scored 16 points and Manu Ginobili had 14 for the Spurs. Parker had 10 points and eight assists before being carried off the court, careful to not let his left foot touch the ground.
Parker had tumbled to the baseline after a hard drive to the basket, and immediately began writhing on the floor. Television replays showed that Parker appeared to awkwardly plant his foot during the drive.
It's not the first time Parker's had trouble with the foot.
Parker missed several games earlier this season after spraining his left ankle Nov. 6. He has also been struggling with plantar fasciitis in the same foot all season.
The Hawks haven't won in San Antonio since 1997. But this lopsided loss - San Antonio led by as many as 28 in the first half and never trailed - was perhaps worst than most would have expected.
The Spurs entered stuck in their worst slump of the season, having lost five of six while betraying their defensive identity. The Hawks, meanwhile, came in leading their division this late in the season for the first time since 1999.
But Atlanta never really got close in this one.
The Spurs matched a season-high with 66 first-half points and held the Hawks to 40 percent shooting. In their previous three losses, San Antonio let their opponents shoot over 50 percent, much to the dismay of Spurs coach Gregg Popovich.
Josh Smith had 14 points and 16 rebounds for the Hawks.
Notes: Spurs F DeJuan Blair was selected to play in the Rookie Challenge game Feb. 12, ahead of the NBA All-Star game. Blair joins Detroit's Jonas Jerebko as the only second-round picks on the rookie team. ...The Hawks had beat Dallas and Houston on the road, but were denied their first 3-0 sweep in Texas since 1990-91.
