The Grizzlies' youth movement is starting to show results.

Memphis won its fourth straight game yesterday, beating the visiting Miami Heat, 102-86. Rookie O.J. Mayo had 28 points, and Rudy Gay added 18.

"As long as we play together, open it up for each other making an extra pass, a screen to get your teammate open, then I feel it makes the game a lot easier for us," Mayo said.

Memphis' winning streak is its longest since winning the last five games of the 2005-06 season. Darko Milicic matched his season high with 13 points, and reserve Mike Conley had 12 for Memphis, which at times has started rookies, Mayo, Marc Gasol and Darrell Arthur. Eight of Memphis' 14 players are 23 or younger.

Memphis has scored at least 100 points in all four wins during the run, and has turned up the defensive pressure: Miami star Dwyane Wade was 5-for-16 from the field and the Heat shot only 36 percent.

Wade finished with 17 points in his second straight subpar game, after entering yesterday's game averaging a league-best 29.1 points. Wade shot 9-for-24 in the Heat's loss to Atlanta on Friday night.

Michael Beasley led Miami with 20 points, and Joel Anthony had 12 points and 13 rebounds for his first double-double of the season.
