Portland overcame a 16-point deficit in the second half despite not having Damian Lillard, who missed the game after straining his right hamstring during practice on Thursday.
“To get a win without Dame was very important,” Trail Blazers coach Terry Stotts said. “The way we came back, down 16, was important. To find a way to finish a game was important. So, I think there was a lot of positives to take from this game.”
Powell’s driving layup with 22.8 seconds remaining gave Portland a 107-106 lead. DeRozan missed a jumper from the wing with 9.2 seconds left, but Jakob Poeltl tipped the rebound out to Rudy Gay, who missed a 3-pointer. Poeltl got the rebound but missed a 17-footer as time expired.
The Spurs also had two turnovers in the final 2 minutes.
“We played hard the whole night,” San Antonio coach Gregg Popovich said. “But down the stretch, too many mistakes on the defensive end and a couple of turnovers.”
The Spurs fell to 2-7 in April after blowing another lead in the final minutes.
“When you have a win like this on the road, and you come from 16 down, you have to have a lot of contributions from different people,” Stotts said.
McCollum and Powell combined for 15 points in the final quarter.
“For us, it’s just about taking care of business with 16, 17 games left,” McCollum said.
DeRozan and Popovich argued that a foul should have been called during the final possession, without success.
“We just came up short, made some mistakes and they capitalized on them and they won the game,” Murray said.
Portland closed the third quarter with a 24-10 run and scored the opening basket of the final period to tie the game at 85.
WISHING ALDRIDGE WELL
Popovich said he was “really worried” when he first heard former Spurs forward LaMarcus Aldridge was retiring due to an irregular heartbeat. Popovich mentioned the heart arrhythmia Aldridge experienced in March 2017 while with the Spurs.
“It was serious,” Popovich said. “It scared the hell out of him and us. Obviously, it’s popped up again. So, I was just worried about it. He’s had a long, great career. He’s going to be fine financially, and he’s got a lot of good memories, but your health is what makes everything tick. So, we just hope for the best.”
During his 15th season, Aldridge announced Thursday he is retiring immediately after dealing with an irregular heartbeat in what became his final game April 10 against the Los Angeles Lakers.
Aldridge spent 5 1/2 seasons with San Antonio before signing with Brooklyn on March 29 following a buyout with the Spurs.
