Uyaelumo, a 6-foot-10 prospect out of Miami (Fla.) Calvary Christian, announced his decision on Twitter. He opted for the Trojans after taking an official visit to Vanderbilt and an unofficial to Florida.
During the spring and summer, Uyaelunmo played for the Florida Vipers on the Under Armour circuit. Uyaelunmo averaged 7.7 points, five rebounds and 1.8 blocks a game.
Uyaelunmo is regarded as the No. 33 center prospect in the 2017 class.
The pledge gives USC a pair of commitments in the 2017 class. Uyaelunmo joins Georgia native Jordan Usher to make up USC's current class.
