"I just came back yesterday, I'm really tired," he said, having gone home to tryout for the Lithuanian junior national team. "I got to do a lot of thinking when I was in Lithuania and I think Missouri is the best place for me - it's the best fit for me."

"No, it's not going to happen," he said of the UNC visit.
Kleiza confirmed a final three list of Florida State, North Carolina and Missouri -- and said the Tar Heels finished in second.
"Coach [Roy] Williams is a really good guy and a great coach -- one of the best in the business and it was great to meet him," Kleiza said.
Kleiza informed the Carolina staff of his decision today.
