Tilly signed an Exhibit 10 contract with the Thunder on Thursday, Jon Chepkevich of DraftExpress.com reports.
The German 7-footer will now compete for a roster spot during training camp, but presumably, the Thunder will be eyeing him for a spot on their G League affiliate. After steadily progressing during three years at Santa Clara, Tilly transferred to Ohio State for his senior season, averaging 11.0 points, 4.7 rebounds, 2.3 assists and 1.2 stocks per game on 48/23/73 shooting splits.
