Players switch sides in tennis on odd games to ensure fairness. On one side, a player may be forced to look into the sun and have the wind against them while the player on the other side has the wind helping them and the sun behind them. It's not fair to have these sorts of conditions constantly go against one player and for the other, so players switch sides to neutralize any effects from the conditions.
