Derrick Williams, who is projected as a first round pick if he declares for the draft, scored 22 points, grabbed 10 rebounds, and blocked a potential tying shot with less than 2 second left to seal Arizona's 77-75 win over Memphis.

With Arizona leading by two with five seconds left, Memphis guard Joe Jackson missed a free throw. Forward Wesley Witherspoon grabbed the offensive rebound and seemed to have an opening at the rim. However, Williams came out of nowhere to send Witherspoon’s attempt the other way.

Williams was 9-for-9 from the free-throw line and hit the go-ahead 3-point with 3:51 remaining to put Arizona up 68-65.

Wesley Witherspoon confirmed he will be coming back to Memphis next season.

"I signed to play four years at Memphis and that's what I'm going to do," he said. "It hasn't even crossed my mind to be leaving. I have no idea where people get that."

But Will Barton may be a one-and-done even though he has failed to impress scouts.

"I still could be," he said. "The year isn't over yet. I'm not going to lie, I'm not throwing it out of the woods yet."

Ray Penn has decided to transfer from Oklahoma State.

Penn was suspended indefinitely by Travis Ford two weeks ago.

“He won't be coming back,” said Ford, who did not elaborate further.

Penn started 10 of the 27 games he played in this season, averaging 5.9 points and 2.1 assists a game.

Ford said Penn remains in school, working to remain eligible as he seeks a transfer.

“We have encouraged him to make sure that he continues,” attending class, Ford said. “He's told some people about possible places he may be headed.”

A logical destination for Penn could be Houston, where he is from and where former Cowboys'  assistant James Dickey  just completed his first season as coach.
