The Pistons kept their slim playoff hopes alive for at least another day, coming back from a 19-point second-half deficit to defeat the Boston Celtics, 115-111, Saturday night at The Palace of Auburn Hills.

The Pistons trailed 82-63 early in the third quarter with the Celtics making 13-of-19 3-pointers at the time.

Then the Pistons picked up their intensity at the defensive end, limiting the Celtics to 1-of-12 from long range the rest of the way.

“The difference was the way we fought through screens in the fourth quarter compared to the first three quarters,” Pistons interim coach John Loyer said. “Really, the last four or five minutes of the third quarter I felt our intensity picked up. We held our own, cut it to 10 points, then kept up the intensity.”

The Pistons pulled within 10 (95-85) heading into the fourth quarter, then limited the Celtics to 16 fourth-quarter points, and they did it without Josh Smith on the floor. Smith had 11 points without a rebound in 26 minutes, 58 seconds.

Jonas Jerebko led the comeback, making consecutive 3-pointers to give the Pistons a 100-99 lead. Rodney Stuckey made a 3-point play (basket and free throw) during the comeback, and rookie guard Peyton Siva also played well.

The Celtics, who were already eliminated from playoff contention earlier this week, put 65 points on the board in the first half, making 8-of-12 3-pointers.

Then the Celtics made five more long-range shots to open up a 19-point (82-63) lead in the opening minutes of the third, resulting in Loyer calling a timeout in search of answers. None came — until late in the third quarter.

Oh, and all of this happened a day after the Brooklyn Nets made 15-of-31 3-pointers in a 116-104 win over the Pistons.
