Alford announced the signing on his Instagram.
Alford, 22, averaged 9.3 points on 43 percent shooting in 19.0 minutes per game with the Warriors’ summer league team. As a senior at UCLA, he averaged 15.5 points and shot 43 percent from 3.
The Thunder currently have 16 guaranteed contracts (15 is the maximum), but Alford will be in camp with the opportunity to potential sign a two-way contract with the team later.
Alford drew interest from a number of teams, but he selected the Thunder based on their positive developmental track record, particularly in using their G League affiliate.
