Infielder Tsuyoshi Nishioka and the Minnesota Twins have agreed to a three-year, $9 million contract with a club option for 2014, the American League club announced Friday.

The Twins and Nishioka, who arrived in Minneapolis from Japan on Thursday, finalized the deal after he passed his physical. The club said it would introduce the 26-year-old switch hitter on Saturday. He will fill one of the middle infield roles while adding speed to the lineup.

"Everything has gone smoothly. I want to feel good and pour all my strength into this team," said Nishioka.
