Check Swing Mechanic

[kcg NC2Ablu]

correct me if I am wrong but is this referring to the ASA Mechanic?

if it is this makes no sense. I know in NCAA your supposed to take your mask off with your left hand get from behind the catcher to where its highly visible and ask the question of swing however your supposed to phrase it. I usually make very good eye contact with my partner so that they know I am comming to them for the check swing and arent caught off gaurd then I will ask the question of "swing?" I have also been told that it is ok to say "do you have a swing?" pr something to that effect. thats in reference to NCAA. PONY that is also accepted. and if it isnt I am sure my local UIC will see this and correct me.
