SAPPORO, Japan (AP) -- Shohei Otani struck out 10 batters over six scoreless innings as Japan beat South Korea 5-0 in the opening game of the Premier12 baseball tournament on Sunday.
Otani, billed as Japan's ace, lived up to expectations in the game played at Sapporo Dome. The 21-year-old right-hander notched three consecutive strikeouts in the fifth inning after South Korea had runners at first and second with no outs.
The quadrennial tournament, which features the top 12-ranked nations, is being organized by the World Baseball Softball Confederation.
