规则10.07
F)除10.07(G)之情形外，
于最终局击球员击出安打而获得超过对方的致胜分时，
对该击球员只给予与获致胜得分之跑垒员所进的垒同数的垒打，
但击球员亦须安全进至该数目之垒。
【原附注】依照6.09及7.05之各项规定，准许击球员获得数个安全进垒权长打时，
亦适用本项规定。
【注】击球员须正规触及上述相同之垒数，又例如最后一局，跑垒员占二垒时，
击球员击出跳入观席之致胜安打时，击球员为获二垒，须正规地到达二垒。
但跑垒员占三垒时，击球员击出前述之安打，虽也进入了二垒，但记录上
仅给予一垒打。
PS 规则6.09 7.05就是指那些如场地二安那种规则安打,

规则10.06
(f) Subject to the provisions of Rule 10.06(g), when a batter ends a game with
a safe hit that drives in as many runs as are necessary to put his team in
the lead, the official scorer shall credit such batter with only as many bases
on his hit as are advanced by the runner who scores the winning run, and then
only if the batter runs out his hit for as many bases as are advanced by the
runner who scores the winning run.
Rule 10.06(f) Comment: The official scorer shall apply this rule even when
the batter is theoretically entitled to more bases because of being awarded
an "automatic" extra-base hit under various provisions of Rules 6.09 and 7.05.
