SOME USEFUL TIPS FOR MARKERS
Arrive wearing appropriate attire. Have chalk or spray-chalk, a measure, and learn where the Umpire Kit is located. Learn the logos on the players’ bowls immediately. Being a marker requires constant attention to the head, the players, and the adjacent rinks.
Do not engage the players in conversation and only chat with them if they initiate it.
When the jack is being delivered, the best places to stand are on the bank above the centre line or by the centre line next to the ditch, being careful not to block the view of the centre mark.
During play, the ideal position to stand is 5-7 feet behind, and 2-3 feet to the side of the jack. Do not let yourself be distracted from the many relevant aspects of the game you are marking. Refrain from moving towards the head to look it over unless a player requests information.
Answer questions about who is holding shot if one bowl is obviously closer to the jack than the other. If it isn’t obvious, be safe and smart by signalling, “it’s a measure.” Experienced markers sometimes say, “it’s a measure, but I favour ____.” In general, do not volunteer information, but when a player asks a question, don’t make them continue asking related questions. For example, if a player asks, “am I holding?” your answer should include howmany up or down they are. If they ask, “am I jack level?” you could say “no, you’re 6 inches behind.” Whenever possible use hand signals.
Inform neighbouring rinks of an imminent running shot.
When centring the mat, the marker should stand by the ditch in front of the rink marker. He should then instruct the bowler to move the mat either to the left or to the right if necessary.
Possession of the rink will belong to the player whose bowl is being played. As soon as each bowl comes to rest, possession of the rink will transfer to the opposing player, after allowing time for marking a toucher as soon as it comes to rest.
When using the wooden baton to set the jack so that it is two metres from the ditch place the tip of the white end on the front edge of the ditch and then place the jack alongside the tip of the black end.
Do not volunteer to measure, but do so if requested by one or both players
