Los Angeles, CA -- (Sports Network) - The Los Angeles Clippers signed Blake Griffin, the top overall pick in the 2009 draft, on Thursday.

Per team policy, terms of the deal were not disclosed.

The 2009 National Player of the Year, Griffin averaged 22.7 points and 14.4 rebounds in his sophomore season for the Oklahoma Sooners.

The 20-year-old led the nation in rebounding and double-doubles (30) and helped the Sooners advance to the Elite Eight in the 2009 NCAA Tournament. His 504 rebounds were the highest season rebound total in college basketball since Larry Bird grabbed 505 boards in 1978-79.

The 6-foot-10, 251-pound Griffin was named to the All-Big 12 Team as a freshman in 2007-08, and last season he finished second in the nation in field goal percentage (.659) and 11th in scoring (22.7).
