For the Sixers, who played in front of a crowd of 16,314 at the Wachovia Center, it marked the first time they had won three in a row since Nov. 5, when they defeated Miami to start the season 3-0.
Of course, things haven't gone all that well for the Sixers since that date - they lost 12 in a row and 19 of 21 after that start - but this is a team that seems to be on the rise and gaining in confidence.
"I thought we had a lot of guys making plays at the end," said Korver, who matched Andre Iguodala for team-high honors with 27 points. "It wasn't just one guy. We had a lot of guys make plays, and that's a really good sign. Hopefully, it's something to build on."
The Sixers, who upset the Phoenix Suns two nights before, came out flat in the first half, negating 59 percent shooting with 12 turnovers and a 14-2 disadvantage in second-chance points to trail by 48-45. They finally picked it up in the second half, but the Grizzlies hung in; the game saw 24 lead changes and 20 ties.
The Sixers looked as if they might be home free after Iguodala's reverse layup with 19.8 seconds left in regulation gave them a 103-100 lead. But Mike Miller, who entered the game leading the NBA with 174 three-point baskets, drained a three-ball with 4.9 seconds remaining to force OT.
The Sixers stayed strong in the extra period. From a 105-105 tie, they took the lead for good on Korver's two free throws with 2 minutes, 17 seconds to play. The Grizzlies were held to 3-of-9 shooting in the extra period.
The Sixers had their hands full dealing with 7-foot Memphis center Pau Gasol, who finished with 31 points, 13 rebounds, 6 assists and 3 blocked shots. To make matters worse, Samuel Dalembert picked up his fifth personal foul with 6:52 left in regulation, but he played all but 4.9 seconds the rest of the way.
