To put it into proper context, an ace is a serve that successfully lands in the service box and does not touch the receiving player’s racquet. As far as I am aware, an ace normally occurs when a player serves at the middle of the court or out wide because it’s harder for the receiving player to get their racquet on the ball. It is a good technique to quicken the pace of a tennis game. Subsequently, I want to inquire if there are betting sites which allow punters to stake on the total number of aces that could occur in a tennis match.
