Clippers sign Griffin

LOS ANGELES -- The Los Angeles Clippers have signed Blake Griffin, the No. 1 overall pick in the NBA draft.

The team said Thursday that Griffin's deal was official, but terms were not announced.

The 20-year-old center averaged 22.7 points and 14.4 rebounds last season at Oklahoma before leaving two years early to enter the draft.

Griffin is playing on the Clippers' NBA Summer League entry in Las Vegas next week.
