The Blue Jays provide MLB with access to its on-field operations department, and the decision is based on the same criteria the team uses during the regular season.
Temperatures are expected to be around 12 degrees Celsius (54 Fahrenheit) for the opening pitch. While the roof decision is made on a game-by-game basis, it's expected to remain closed for the remainder of the Blue Jays' postseason run as the colder fall weather sets in.
The Blue Jays were 38-14 with the roof open at home this season and 11-14 with it closed. They were 4-0 in other situations, which includes either the roof being open and then closed midway through the game or vice versa.
