NORMAN, Okla. (AP) — Former Oklahoma star Blake Griffin returned to campus Saturday for the dedication of the Griffin Family Performance Center.

The AP Player of the Year in 2009 made the largest donation ever from a Sooner basketball player to help with the $7 million center.

Griffin plays for the Detroit Pistons, and the NBA club will train at the facility before its Oct. 3 preseason game against the Oklahoma City Thunder.

The school’s Board of Regents agreed to name the facility for Griffin, but he wanted his family included. Griffin said his brother, former Sooner Taylor Griffin, helped with the planning.

The facility includes basketball training courts, free weights and areas spaces for stretching, cardiovascular training and strength testing. There are locker rooms, an exam and recovery area and a fueling station. The approximately 16,000 square-foot addition has been in use the past two months.
