So after discussing this with
@gn and carefully reviewing the situtation, we both agreed that it's only fair if
@TripleATeam 's cancellation is valid, but
@PDJ 's is not. Unfortunately, PDJ did not make the cancellation in time, so the orignal pick of Sinner over Nadal will stand. TripleATeam was able to get the cancellation in on time, so this match won't count toward his picks.
Though, I understand that there's some jockeying going on to try and determine the outcome as it relates to the leaderboard, please be aware that when you make these last second picks, you run the risk of them not being counted. It's highly recommended that you carefully consider your picks or cancellations and get them in well before the match starts.
