Back injury from Rogers Cup, Pegula takes her place, she lost to Diyas in qualies
That's not true. Pegula vs Diyas will be played after Federer vs Londero. The Match was originally scheduled to start 20.30 Local and has been pushed back to about 21.30 Local now.Her match has been canceled. She was probably told she might have to play 2 matches tomorrow. If that's the case, I can see why she decided to go home.
