There are two main points in this video by Jo Shattuck:
- You need a variety of racquetball serves. Change your serve height, speed, or angle so it does not become predictable.
- After hitting your serve, relocate out of the service box into center court position. Maintaining control of center court position will enable you to win the rally. This position is 1 to 2 feet behind the 5 ft service encroachment line.
