Can’t help but feel something psychological really did get to Mizutani here, in the confident way we all feel with 6 game points. Take the serve at 10-7 for example. He serves from his backhand side with a sidespin that one would expect to curve toward the forehand. But he sits paralyzed watching his serve, not reset at all to handle the down-the-line to the forehand. Not something he’d be usually unprepared for on when delivering that serve, I think.
