Good match!

Most volley servers meet the ball in between the 6:00 and the 7:30 position. The guy in the white shirt is consistently meeting the ball in the 8:00 position. You would have to breech the 9:00 position to be illegal.

do you know how many teams played in this division?

Seems about right for 3.0. at 72, I am hoping to play next year at 4.0 Singles. I still have a ways to go.

Did any of the Hanlons play in this tournament?

I thought everybody looked tired the third game. Also thought the guy in white was serving illegally. Some of his serves were struck with a horizontal motion, while the rules require an upward motion. As for the woman in the blue visor, I think if she were not a 3.0 they wouldn't have gotten this far in the tournament. Again, she looked tired most of the time. As a 75-year-old myself I can sympathize.

Just watched a few serves of the guy in white, in slow motion to confirm, and his serve is illegal. The top of the paddle is above his wrist

I wondered about the serve at first as well. That being said, I cannot believe his partner in white top and blue visor is a 3.0 player. She is just terrible. That spastic upward slap as a lob is beyond cringeworthy. Perhaps she was just tired from several earlier matches but that was a mess.
