The Changeover

The tennis term, "Changeover" is a 90-second pause in a tennis match during which the players change sides of the court. Depending on what side of the tennis court you're on, the wind speed, glare of the sun, and noise level can vary significantly. In order to maintain fair play, tennis players change ends after every odd-numbered game. Most competitive tennis associations, professionals included, allow for a 90-second break during this changeover.
