Tiago Splitter added 16 points for the Spurs, who relished a convincing win over the Southeast Division leaders after losing two of their previous three and barely squeaking past woeful New Orleans on Monday night.
Jeff Teague led Atlanta with 22 points. Kirk Hinrich made his season debut, after missing 18 games recovering from shoulder surgery, and scored seven points in 14 minutes.
Joe Johnson had 10 points for Atlanta. The 22-point blowout was a rare embarrassment for the Hawks (13-6), who had won six of seven.
Atlanta’s few losses this season included a triple-overtime heartbreaker to LeBron James and Miami, and a two-point defeat to Derrick Rose and Chicago.
The Hawks got manhandled this time, largely by an underperforming outfit of San Antonio role players.
Tony Parker had 15 points, and Tim Duncan scored only six and grabbed 11 rebounds. San Antonio’s reserves outscored the Hawks bench players 51-27.
Johnson, who had averaged 23 points in Atlanta’s previous seven games, shot 5 of 12 from the floor. Josh Smith added 13 points on 6 of 17 shooting.
The Spurs shot 51 percent from the floor, marking the first time this season that Atlanta has allowed an opponent to make more than half its shots.
The Spurs are 10-1 at home, but are 2-6 on the road. They have three more home games before hitting the road for most of February.
