Grizzlies 91, Thunder 89: Mike Conley capped a 20-point effort with a 3-pointer in the final minute as visiting Memphis kept alive the best start in franchise history.

Courtney Lee hit all three of his 3-point attempts en route to 17 points and Zach Randolph finished with 16 for the 6-0 Grizzlies, who made 9-of-18 from beyond the arc and 5-of-11 in the fourth quarter. Marc Gasol chipped in eight points, nine rebounds and three blocked shots.

Reggie Jackson registered 22 points - 12 in the final seven-plus minutes - to lead depleted Oklahoma City, which hurt itself by going 3-of-11 from the line. Jeremy Lamb had 17 points in his season debut and Serge Ibaka made a career-high four 3-pointers to finish with 16 points, but missed a potential game-winning triple at the buzzer.

Jackson's runner and Lamb's 3-pointer tied it at 81 with just over four minutes left and the Thunder seized an 89-87 lead - their only advantage of the game - on Jackson's 3 with 53 seconds to go. Conley answered moments later with his decisive make from long range, Jackson missed on the other end and a five-second violation later took away another chance for the hosts before Ibaka's desperation shot was off.

Memphis led by single digits throughout the first half and closed it on a 7-0 run to carry a 49-40 lead into the locker room. The lead ballooned to 14 points early in the third before a 12-0 surge by the Thunder made it a two-point game and set up a tight second half.
