Dallas Mavericks coach Rick Carlisle ripped into guard O.J. Mayo during Monday night's loss to the Memphis Grizzlies.

Carlisle shot a disgusted stare at Mayo after calling a timeout. Mayo had two sloppy turnovers and a weak foul over a 90-second stretch.

"I called that timeout just to get you out of the game!" Carlisle screamed at Mayo in the huddle, according to one player.

Carlisle then made his criticism loud and clear during his postgame news conference.

"I just want to see him show up," the coach said. "I just want to see him show up and compete. He didn't compete tonight.

"And I tell you, with all the time we've put into helping him develop and bringing him along, in the biggest game of the year -- an opportunity to be a winning team -- for him to show up like he did tonight, I was shocked.

"Look, sometimes guys have bad nights, so make sure to put that in there, too."

Mayo was especially poor all season against the Grizzlies, a team that tried to trade the former No. 3 overall pick repeatedly and showed no interest in re-signing him last summer.

"He just had a bad night," Carlisle said after making a point to mention that the coaches showed Mayo film at halftime "where he was virtually just standing around defensively" and essentially implored him to mentally check into the game. "I guess I'll write it off to that.

"But I tell you what, if I was playing against my former team, I'd come out ready to go. I'd come out ready to go at them. But that's me. You know, that's me."
