※ 引述《sean0000 (三餐都吃方便面)》之铭言：
: 大家好
: 小弟是天龙蛇
: 想请问一下
: 大联盟可不可以只用24个人
: 当然这当中有可能是为了省钱
: 或是找不到够格的人上大联盟等等
: 如果一定要填满25人名单的话
: 史上有没有出现过只是为了填名单
: 而让某位球员在大联盟名单
: 但是开季七场以上了，甚至整季
: 都没让这位选手上场
: 就这样真的只是roster filler的角色
: 有这方面的专家能帮小弟解答一下吗？
官网的规则摘要
http://mlb.mlb.com/mlb/official_info/about_mlb/rules_regulations.jsp
The 40-man roster:
A Club's 40-man roster is a list of all the players currently reserved by
a Club at the Major League level. The Major League Rules permit each Club
to reserve a maximum of 40 players (excluding players on the 60-day disabled
list) at any one time. From September 1 through the end of the season the
entire 40-man roster is eligible to play for the Club at the Major League
level. From Opening Day through August 31, however, a Club may use only 25
of its 40 players in the Majors.
所以 40 人和 25 人都只是上限, 不需要填满
找不到正式规则的档案, 以下来自 The Biz of Baseball
2008 年版的大联盟规章
http://bizofbaseball.com/docs/MajorLeagueRules-2008.pdf
里面可以明显看到只有规定 maximum
