Walker and Thomas' sled turned upside down near turn 10 and slid all the way over the finish line, but the pair clambered out and walked away unharmed.
Minichiello and Cooke produced their fastest slide of 53.73 seconds on their second run at the Whistler Sliding Centre for a combined time of one minute, 47.58 and a 0.19-second advantage over Walker and Thomas.
Last week, before the Knicks' game with the Spurs, Thomas sat down with assistant coach Darrell Walker to help sketch out plays to run against San Antonio, where Thomas played four years ago.
