明年用球降低恢復係數 全壘打將不再滿天飛
中華職棒今年上半季陷入「彈力球」風波,上半季四隊合計敲出327支全壘打,測出的恢
復係數,2次檢測分別為0.574與0.571,雖然符合規定,但偏離中間值,讓中職不得不在
球季中換球,強力要求製造廠商,把比賽用球的恢復係數控制在0.550至0.570,並盡量維
持在中間值0.560。
降低恢復係數後,下半季目前四隊合計僅有165轟,全壘打頻率大幅降低,且今天領隊會
議還做成決議,明年球季的比賽用球,恢復係數中間值將再往下降,中職副秘書長王惠民
說:「領隊會議做成決議,明年比賽用球的恢復係數中間值,將降為0.550。」
理論上,若中間值調降,規定的係數範圍以及建議係數範圍,都需要往下調降。目前中職
比賽用球恢復係數規定為0.540至0.580、建議值為0.550至0.570、中間值0.560,由於恢
復係數規定與建議值,都已列在合約中,所以若要修改範圍,王惠民表示:「還要再跟廠
商討論,但中間值下修已做成決議。」
恢復係數中間值下降後,將使長打頻率降低,若參照近年中職比賽用球的恢復係數檢測表
,僅有2014年的0.557最靠近0.550,該季全年四球團僅有209轟,是近7季最低的紀錄,明
年確定將扭轉中職打高投低的狀況。(王翊亘/台北報導)
