山本由伸春訓第1天投Live BP。(圖/翻攝自道奇推特)大聯盟春訓第1天就投Live BP,道奇先發投手山本由伸確定會在日本經典賽首戰登板,對手就是台灣!日前日本隊公布30人正選名單時山本就曾透露「目標就是第一名」。他預計在春訓熱身賽登板2場,之後返日向侍武士對報到。
山本由伸Live BP吸引大谷翔平、佐佐木朗希2位日籍隊友在本壘後方觀看,相較於大谷帥氣的單膝跪地,朗希被拍到是用雙膝跪地的方式看山本投球。在道奇是隊友,在經典賽變成對手的金慧成有站上打擊區和山本對決,從曝光的畫面看,金慧成敲出右外野平飛安打。
山本由伸提前在8日進駐道奇位在亞利桑那的春訓基地。根據駐美日媒的觀察,山本由伸的下半身看起來比去年更扎實。道奇球團相關人士也讚嘆「山本的體格,尤其是下半身,變得更加強壯了。」山本由伸本人也透露「為了應付WBC,這個休賽季確實下足功夫進行訓練。」
