Often times during a game, players will be called upon to get a runner around the bases with a fly ball or a bunt. This is one of the [tag]baseball plays[/tag] used to teach this. 
What you need (set up): A full infield, a batter and a runner on first, second or third.
How this drill works: The batter must get the runner to the next base, but only using one of two plays: a bunt, or a sac fly. The fly ball must be deep enough to advance the runner and the bunt needs to be effective enough not to be a double play ball.
Batters should work on hitting a fly ball on purpose and also bunting to the best areas to avoid outs. These skills are important in this game situation.
Result: This is one of the most common plays in [tag]baseball[/tag]. If you can get your team to execute [tag]sacrifice plays[/tag] with regularity, then you will notice your overall run total increase considerably.
