The Grizzlies won despite blowing a 10-point lead with 7:38 left in regulation and 23 turnovers that San Antonio turned into 31 points.
Mike Conley set a franchise postseason record with 35 points, and Gasol finished with 16 points after shooting 5 of 12 for the game. He also had 12 rebounds.
The Grizzlies overcame another postseason personal best from Kawhi Leonard who had 43 points. He rallied the Spurs by scoring the last 16 points of regulation, but missed a 21-footer short of the rim with James Ennis defending him just before the buzzer. Leonard tied it at 108 with 17 seconds left with a 3 from the left corner.
Game 5 is Tuesday night in San Antonio.
