日本高中棒球慣用金屬棒
有鑑於近年來甲子園比賽長打倍增
投手為了避免被擊出長打
投球數+變化球比例都隨之增加 投球負擔加重
再者就是2019年夏季甲子園
當時有打者揮出的球直接打到投手的臉 造成投手臉部骨折送醫
對此高中棒球聯盟擬定保護投手+投打平衡的方針 進行後續改革
去年春甲開始實施投手球數限制 接下來輪到打者使用的球棒
考量到木棒比金屬棒價格高 對於學生棒球是一大負擔
因此排除了採用木棒的可能性
以研發比較不彈+質感近似木棒的金屬棒為目標
一來降低打者擊球命中投手時的殺傷力 二來縮短擊中球的飛行距離
具體作法是將球棒直徑縮小 棒頭金屬厚度增加
但是球棒長度重量都維持不變
今天聯盟在關西大學北陽高校的練習場
由該校選手使用木棒/美國BBCOR認證合成棒/4種新規格測試棒/現行金屬棒
一共7種球棒進行試打
有專家在試打過程中記錄揮棒速度/擊球速度/飛行距離等數據
預定今年完成新規格制定 明年開始使用新規格球棒
各校有2年時間適應 2024全面以新規格球棒比賽
新規格球棒對於未來比賽的預期效應還有:
打者更要確實擊中球心
投手放膽投速球和打者對決 投球效率提升
低得分比賽機率提高 對於非傳統棒球名校是利多
