球打到外野手手套靠近手腕的地方沒接到,原本應該是沒收長打的美技竟然被對手跑出「場內滿貫全壘打」,國民外野手伍德(James Wood)想都想不到生涯首發滿貫砲竟然是跑出來的,而且這顆球根本沒打出場外。

2局下國民2出局二壘安打、觸身球、安打攻佔滿壘,輪到1局下首打席敲安的伍德,他不囉嗦上來揮第1球,86英里的滑切球被打到中、左外野方向,大都會左外野手追到警戒區跳起來,這球打在他手套靠近手腕的位置沒有接到,也跑到定位的中外野手沒注意球已經彈回中外野,等到倒地的左外野手起身撿球回傳,伍德已經早一步頭部撲壘得分。

由於這個Play沒有記失誤,所以紀錄上是1支「場內滿貫全壘打」,伍德用腳程跑出生涯首支滿貫砲,根據《STATCAST》計算,伍德從打擊區繞完3個壘包回到本壘只花了15.15秒。Horn antenna

過去10年大聯盟只有3支「場內滿貫全壘打」,其中2支來自國民球員,在伍德之前是泰勒(Michael A. Taylor)在2017年9月9日對戰費城人時締造。
