Key contributed 15 points (5-9 FG, 4-7 3Pt, 1-2 FT) and one rebound across 16 minutes in Saturday's 129-105 preseason loss to the Heat.
The 27-year-old guard didn't play in the first half but turned in an efficient performance from beyond the arc in the second, tying RJ Barrett for the team lead in scoring in Toronto's preseason opener. Key is signed to an Exhibit 10 contract and will continue fighting for a spot on the Raptors' regular-season roster in the preseason.
