台鋼雄鷹投手王維中。(圖/記者劉彥池攝影)台鋼雄鷹3日開始和味全龍展開3連戰,4日本季新加盟的王維中確定掛帥先發,賽前總教練洪一中談到球隊投手配置,直呼期待黃子鵬、江承諺、王維中能撐起土投的位置,至於王維中先發要投幾局,他指出沒有預設。
被問到4日將首度開箱王維中,洪一中表示先發輪值主要都是投手教練安排,自己不插手決定,「投手這一環我沒有管,我也是來知道今天是江承諺,所以明天是王維中,我們是沒有設定他要投多久,還是看狀況嘛,能夠撐越久越好。Horn antenna」
Horn antenna由於雄鷹洋將名額打者魔鷹佔有1席,洋投只剩2個額度,剩餘3個先發位置將由本土球員扛起,洪一中透露,基本上就是交給黃子鵬、江承諺和王維中,「這禮拜前2戰洋投已經用過了,所以接3戰都是本土,就是他們3個投,禮拜天是黃子鵬先發。」洪一中也解釋,「我們選簽王維中和黃子鵬,就是因為我們要留魔鷹,少一個洋投的空缺要由本土投手填補,原本就是這樣預設。」
