FIELDING: GROUNDER FLYBALL GROUNDER GAME My favorite drill is called grounder Flyball grounder. It goes like this: Line all of your players up at third base. Hit a hard grounder to the first person in line. As soon as they throw it in to the coach throw a high fly to first. Make the player hustle to get it. as soon as they throw it in hit another grounder to third, thus making them run back across to get it. This drill is good for footspeed, fielding and personal effort. Speed it up as players advance.
