8 "Foul Shot" or "Touch" If a ball is intentionally struck twice, or struck before it comes over the net, or a player touches the net while the ball is in play, or a ball in play touches a player, or anything that he/she is wearing or carrying falls into the opponent's court (Rule 24 of the Rules of Tennis). 9 "Hindrance" If a player deliberately or involuntarily commits an act which hinders his/her opponent in making a stroke (Rule 26 of the Rules of Tennis). 10 "Wait, please" If an interference or disruption makes it appropriate to delay the beginning of a point or second serve. 11 Overrules/Corrections "Correction, the ball was good" to overrule a clearly incorrect "Out" call. "Out" or "Fault" to overrule a clearly incorrect "Safe" signal. I HAND SIGNALS The hand signals are as follows: 1 "Out" or "Fault" Arm fully extended sideways pointing in the direction in which the ball was "Out" or "Fault", palm of hand facing the Chair Umpire, fingers extended and joined. The hand signal must never be used instead of the verbal call. The hand signal is in addition to and secondary to the verbal "Out" or "Fault" call. 2 "Good Ball" or "Safe Signal" Open hands with palms down discreetly. There is no verbal call for a good ball. The hand signal is used in silence, during a rally and on point-ending shots to verify that a ball was good (approximately three (3) feet (1 metre) inside the line). 3 "Unsighted" Hands in front of face below eyes, backs of hands visible to Chair Umpire. The hand signal shows that the Line Umpire is unable to make a call due to his/her vision for some reason being obscured. There is no verbal call, the hand signal is used in silence. 4 "Net" or "Through" Arm fully extended upwards at the same time the verbal call "Net" or "Through" is made. 5 "Foot Fault" Arm fully extended upwards at the same time the verbal call "Foot Fault" is made. 6 "Correction" Arm fully extended upwards at the same time the verbal call "Correction" is made. 20
