Rule 8.4 (3) says 6hr then walks. Is this correct?
NO, that is the HR Rule for Senior (over age 50) Major teams ... The HR Rules for the Men's 40-Masters are as follows ...
• Major+: Ten (10) per team per game, outs thereafter
• Major: Eight (8) per team per game, outs thereafter
• AAA: Six (6) per team per game, outs thereafter
