Minnesota Twins second baseman Tsuyoshi Nishioka of Japan broke his left leg on a hard slide by New York Yankees outfielder Nick Swisher during their game Thursday. Nishioka signed a three-year, $9 million contract to join the Twins after winning the Japanese Pacific League batting title for the Chiba Lotte Marines. "Swisher's a clean player. It was a good slide," Ron Gardenhire told reporters.
