LOS ANGELES (AP) -- The Los Angeles Clippers signed center Diamond Stone, their 40th overall pick in this year's draft, on Thursday.
   He averaged 12.5 points, 5.4 rebounds and 1.6 blocks in his only season at Maryland, where the 6-foot-11 center set the school freshman record with 39 points against Penn State on Dec. 30, 2015.
   Stone averaged 10.4 points and 5.6 rebounds in five games with the Clippers' team in the Orlando Summer League.
   Earlier this week, the team signed forward Brice Johnson, the 25th overall draft pick, and free agent center-forward Marreese Speights.
