Pastner promoted to head coach

Memphis decided to stay in house.

Assistant coach Josh Pastner will be named the next head coach at the school at a news conference at 1 p.m. ET on Tuesday, Memphis athletics spokesman Bob Winn said on Monday.

Pastner, 31, replaces John Calipari, who became the head coach at Kentucky last week. A source close to the Memphis program told ESPN.com that Memphis turned to Pastner to ensure continuity in the program after Calipari's success and subsequent departure.

This is Pastner's first head coaching job. He was a walk-on at Arizona on the 1997 national championship team and after graduation worked his way up on the bench with Hall of Fame coach Lute Olson.

Pastner was the lead recruiter for the Wildcats in Olson's last season two years ago and the top assistant for interim coach Kevin O'Neil during the 2007-08 campaign. Last summer Pastner left Arizona to work for Calipari.

According to the source, the school did inquire into the availability of Massachusetts head coach Derek Kellogg, who was an assistant for Calipari at Memphis, but he just completed his first season at his alma mater.

Memphis made overtures to USC's Tim Floyd, Missouri's Mike Anderson, former Xavier coach Sean Miller -- who took the Arizona job -- and most recently Florida State's Leonard Hamilton.
