20:30 CET - Play is delayed by rain in Montreal for the men's event but the women have already gotten going in Toronto and the day has started with a big upset!

16:16 CET - Following his loss yesterday, Stefanos Tsitsipas (25) has announced that the "collaboration" between himself and his father, who has been his coach throughout his senior career, has come to an end.
The Greek player was given a warning by the umpire during yesterday's match after angrily complaining to his father, who he then said in the press conference afterwards "hasn't been very smart or good" as his coach and has "really disappointed" him.
"In that moment of frustration, there were many mistakes and errors on the part of my coach and father," Tsitsipas said in a statement on Twitter. "As an introvert, I tend to hold in my emotions and build them up until I reach a bursting point. I consider myself patient, so the fact that I reacted this way left me shocked.
"My behaviour on the pitch was unacceptable, and I feel disappointed that I got to a point where I showed a dark side of myself."
