Singles Go has elements of other drills, think Champs and Chumps + Around the World with a little Deep Desperation thrown in for good measure. It will improve your players' overheads, net game, and fitness. Coaches, get your lob feeding skills in order.
One player is selected as first Champ and begins at center of court in net position. All other Challengers are at opposite baseline. One at a time they step in to play singles against the Champ. Feeder/coach feeds first ball to Champ as a high lob.
If Champ wins the point, they stay. Losing Challenger goes to end of Challenger line and next Challenger takes a turn.
If the Champ loses the point, they run to end of Challenger line. The winning Challenger runs to Champ side of court as Feeder is feeding another high lob for them to play.
I used this drill recently with my green ball players. We were working on backhands in this lesson, so I substituted a backhand feed for the overhead. I also added a point play component, first to 10 points wins. They loved it and begged to play it through the end of the clinic, thirty minutes straight.
