Two fans hit big shots on Friday night.
A fan had not hit a half-court shot at a Thunder game since April 12th, 2017.
Both fan contestants had 24 seconds to make a half-court bucket for the $20,000 prize from MidFirst Bank.
The bank has sponsored the half-court competition at every Thunder home game since the 2008 inaugural season of the franchise.
Williamson and Norman became the 12th and 13th winners, respectively.
