It was early in the match, and Roger Federer ended up winning it in straight sets.
So he could laugh at ATP Finals rookie Jack Sock’s move – a “big” distraction that caused him to make an error on what appeared to be an open court sitter.
“It was a big distraction, I’ll tell you that, because it was very big,” Federer said. “That’s what I should have aimed for. That target was bigger than the down-the-line court that I had.”
Federer said it was hardly the first time he’d seen it. But never on such a big stage.
