LAS VEGAS, July 11 First-round draft pick O.J. Mayo led the Memphis Grizzlies to an 88-75 victory over the New Orleans Hornets on Friday in the second of 53 games at the 2008 NBA Summer League Presented by EA SPORTS at the COX Pavilion on the UNLV campus.

Darrell Arthur, also a first-round pick, led the way for Memphis with 18 points. The offensive effort was rounded out by Mayo, who finished with 15 points, and second-year guard Mike Conley, who added 14.

"It was a good game, but we're are a young team, we've got a lot of young players, Mayo said after his summer league debut. I think our main objective is every time we step on the court is to get better. Game or practice, win or loss."

Memphis jumped out to an early 11-1 lead before New Orleans closed to 15-13 at the end of the first quarter behind Hilton Armstrongs five points. The Grizzlies held their lead through the second quarter, owning a 38-30 halftime advantage. Mayo led all scorers with 12 points going at the break.

In the third period, New Orleans closed the gap, pulling within 46-44 with just under three minutes to play. But Memphis closed the quarter with a 14-3 run and put together a 28-point fourth quarter.

Armstrong, a third-year player, led all Hornets with 13 points, while Julian Wright chipped in 12 and five rebounds.

New Orleans and Memphis both return to action Sunday, when they play the Charlotte Bobcats and Los Angeles Lakers, respectively.
