Kaleb Tarczewski will return to the University of Arizona for his junior year.
The 7-footer decided to remain a Wildcat, electing not to declare himself eligible for the NBA Draft.
Tarczewski put up 9.9 points and 6.3 rebounds per game last season.
In Arizona's 33-5 campaign, Tarczewski made strides from his freshman season, scoring three more points per game and increasing his free throw percentage from 63 percent to 76 percent.
Tarczewski will keep his role as the man in the middle for coach Sean Miller's offense, and will continue to be a defensive threat. He has blocked two or more shots in 13 games during his two-year stay in Tucson.
