MEMPHIS, Tenn. -- The Memphis Grizzlies had every reason to ease up in the regular season finale after pushing hard the past three months to reach the postseason.

Instead, they kept grinding and grabbed the No. 7 seed in the Western Conference.

Mike Conley hit two free throws with 1.1 seconds left in overtime, and the Memphis Grizzlies moved up from the eighth seed by edging the Dallas Mavericks 106-105 on Wednesday night.

"We've been holding on very tight for a long time ..." Memphis coach Dave Joerger said. "Getting 50 wins is something you want on your resume as a player, and people remember those. Those are special seasons. It's a standard, a golden standard I think."
