San Antonio dominated a matchup of teams with the second-best record in each conference, leading by as many as 34 points.
Leonard and Aldridge combined to shoot 19 for 28 from the field, but it was veteran point guard Tony Parker who set the tone for the Spurs.
Parker finished with 15 points and eight assists in 23 minutes.
The Spurs raced to a 26-10 lead in the opening eight minutes, and the Raptors never recovered.
San Antonio fizzled when Parker exited for rest, going scoreless for 5:13 bridging the first and second quarters.
Parker’s return helped set up three straight dynamic plays that put the Raptors on their heels and gave the Spurs their largest lead at 54-32 with 2:28 left in the first half.
Green’s steal and half-court pass led to a one-handed, breakaway dunk for Leonard that revved up the sold-out crowd.
Parker dribbled around his back on the run to lose Lowry at the top of the 3-point line, got DeRozan to leap in the paint and then whipped a pass to the left corner for a 3-pointer from Leonard.
Parker then passed under the basket to Aldridge, who tossed it out to Leonard. He faked a shot, dribbled, reset and made a 3 for a 22-point lead.
The Raptors shot 37 percent from the field while failing to reach 90 points for the first time this season.
