PORTLAND — CJ McCollum hit a floater with 5.9 seconds left to give the Portland Trail Blazers a 111-110 victory over the San Antonio Spurs on Sunday night with both teams short-handed.
McCollum finished with 25 points and Maurice Harkless added 19 off the bench for the Blazers, who were without starter Damian Lillard. It was Portland's fifth win in seven games, and third straight victory at home.
Former Blazer LaMarcus Aldridge had 30 points and 14 rebounds, while Manu Ginobili added 26 points, including six 3-pointers, for the Spurs.
Trailing by as many as 12 points in the third quarter, Portland rallied to lead 101-94 on Harkless' 3-pointer with 5:37 left. But Ginobili's 3 gave the Spurs a 105-103 lead with 2:48 left. He added another to extend the lead to 108-105.
McCollum's layup with 1:11 left gave the Blazers back a one-point edge, but he missed an off-balance jumper that would have given Portland some cushion.
After Kyle Anderson's free throws put San Antonio in front, McCollum came through with his floater that gave Portland the winning margin. Aldridge missed a jumper from out front as time ran out.
Spurs forward Kawhi Leonard sat out because of a partial tear in his left shoulder, coach Gregg Popovich revealed before the game.
Leonard sustained the injury during the Spurs' 103-89 win Friday over the Phoenix Suns.
"It's too bad because he was starting to get back into form a little bit after playing a couple of games," Popovich told reporters. The coach said the Spurs would monitor the injury over the coming days.
The game against the Suns was just Leonard's eighth appearance of the season after missing the first 27 games with right quadriceps tendinopathy.
The Spurs also didn't have Rudy Gay (right heel) and Danny Green (groin tightness). Tony Parker also did not play. San Antonio plays again today against the Sacramento Kings.
The Blazers were without Lillard because of a right calf strain. Lillard missed four games because of a strained right hamstring but played in the last two, despite the calf injury.
Lillard leads the Blazers with 24.9 points and 6.3 assists per game. Shabazz Napier started in his place.
Napier helped spark Portland at the start and the game was tied at 27 to start the second quarter.
The Spurs led 53-48 at the half, led by Aldridge with 15 points. Jusuf Nurkic had 11 for Portland.
San Antonio extended the lead to double digits early in the third quarter. Aldridge's layup extended it to 69-57.
Napier continued to stand out for the Blazers, who closed within 74-69 with Harkless' 3-pointer. Harkless added a short jumper and a pair of free throws to pull Portland closer.
Napier's layup gave the Blazers an 80-77 lead near the end of the third quarter but Davis Bertans hit a 3 to pull San Antonio back into a tie to open the fourth quarter.
Napier finished with 15 points.
Al-Farouq Aminu's 3-pointer gave the Blazers a 91-87 lead with 8:21 left, Portland's largest of the game to that point.
Ginobili became the first player in his 40s to score 15-plus points in back-to-back games since Michael Jordan in 2002-03, according to the Spurs.
