The 7-0, 255-pound junior averaged 6.7 points and a team-leading 7.0 rebounds per game while also leading the Trojans in blocks and steals. The Lancaster native previously played at Antelope Valley College.
Dedmon, 24, was not selected in June's draft and will be competing against a number of bodies for a roster spot at next month's training camp.
The Warriors already have solid depth up front with veterans Andrew Bogut, David Lee, Mo Speights, and Jermaine O'Neal, and Dedmon is still considered to be very raw.
Also working against him is the reported signing of the teams' 2012 second-round pick Bosnian center Ognjen Kuzmic.
If he proves his value in camp, Dedmon may warrant a spot in D-League Santa Cruz.
