TOKYO - Shohei Ohtani opened the floodgates with a second-inning grand slam as Japan began its World Baseball Classic title defense by demolishing Taiwan 13-0 on Friday.

The WBC's reigning MVP brought the crowd of 42,314 at Tokyo Dome to its feet as he put Japan on the board with a bomb deep to right field off a one-out curveball from Cheng Hao-chun (0-1) in the top of the second.
