There's a reason why tournaments are separated by age group. These guys would probably lose to 4.5 19+ competitors. I've personally seen (in singles) a senior pro medalist convincingly lose to someone I would assume is at least 0.5 lower in DUPR.
Seemed clear to me at 1:11(freeze frame), left foot on the line. Foot fault good call and you can see the ref staring at his feet. The player obviosly wasn't looking down as he struck the ball.
I don't understand the surprise lobs. a fair number were out or were hammered right back at them, They were winning almost every time with the dink game. Why mess with success? I understand doing a few just to give opposing team another thing to worry about but they lost too many points with these. Great games!
