Loblolly

Of course I found this on a TX website
a TX loblolly aka mud hole

Another one from Daniel Breag - he did not give it a specific name so I will harken back to my rural roots. So simple - tennis face palm moment.

Four players are in, all at baseline. One end of court can hit nothing but lobs. Great for working on overheads and defending against them. Structure it however you like. For example:

Variations

• First team to X points wins; switch ends; best 2 of 3.
• First team to hit X winning overheads wins.
• First team to hit X unreturned lobs wins. 
• For groups larger than 4, divide into teams, have players rotating in after every point. Timed intervals; team who is ahead at end of time, wins.
