日一更
有了大家的鼓励感觉写的更起劲了╰(*°▽°*)╯
有关本垒的mlb通用说明。不知道日本正式比赛是不是也采用这样的情况,不过有关本垒板的规格的话, 想来应该都是统一的国际标准吧。
“Home base shall be marked by a five-sided slab of whitened rubber. It shall be a 17-inch square with two of the corners removed so that one edge is 17 inches long, two adjacent sides are 81?2 inches and the remaining two sides are 12 inches and set at an angle to make a point. It shall be set in the ground with the point at the intersection of the lines extending from home base to first base and to third base; with the 17-inch edge facing the pitcher’s plate, and the two 12-inch edges coinciding with the first and third base lines. The top edges of home base shall be beveled and the base shall be fixed in the ground level with the ground surface.”
