A.8 - Warm-up Times

Once all players in a match have been informed what court they will be playing on, singles players are allowed up to 5 minutes of on-court warm-up time and these warm-up times run concurrently. For doubles, each team is allowed up to 5 minutes for on-court warm-up and while these times do not run concurrently, both teams’ warm-ups must be completed generally within a 10-minute period that starts when the first team begins its warm-up.
