I understand the rule and the pitcher maybe needing one but 1st and the hot corner? Im not sure about that?..Ive been around baseball and softball for a long,long time and Ive seen few injuries from line drives and all of those were youth leagues were there was 10 year olds playing with younger kids like 7 year olds etc. Ive never seen an injury at the corners from line drives..
Now that's just my exp, Ive no doubt others have seen it.. Id like to hear more opinions about it ?
