Seven match points, including up 3-6 in the fourth set tiebreak and Federer saved them all. It was a walk over in the fifth. Sandgren had nothing left. Federer should have lost in the round of 16. He was down 8-4 in the fifth set tiebreak and then won six consecutive points.
"McCoco" finally lost to the 2 seeds. Don't know anything about McNally, but Coco Gauff is the future of the game. She might be the #1 player in the world before she graduates high school. We're all failures in comparison.
It will be interesting to see what happens. I wouldn’t be surprised at all if she never even wins a grand slam. Lots of fame and money at a young age usually doesn’t turn out well.
