Thanks Coach William Vazquez for this drill which was originally posted here.
Two player start as King or Queen or Champ or whatever you want to call them. They are at the net. All other players are divided into two groups and are challenging the King/Queen from the baseline at ad or deuce. Challengers bounce feed; no lobs/lobs do not earn any points. One chance at the feed.
When King/Queen loses 2 points, they are out and join the line of challengers. Points lost do not have to be consecutive. The player they lost the second point to is the new King/Queen. New King/Queen has 3 seconds to run over and take their position at net. First King/Queen to earn 10 points from clean winners is the winner.
If you have a smaller group you can make this one on one as opposed to having two lines playing.
