Ohtani hit a grand slam in the second inning — in the first he doubled on the first pitch of the game but didn't score — as Japan hammered Taiwan 13-0 in Pool C at the World Baseball Classic. It was Japan's first game of four in pool play.
The game was called after seven innings under the mercy rule, which is being used in the WBC. The game is called after five innings if a team leads by 15 runs or more, or after seven if the lead is 10 or more.
