Minnesota Twins infielder Tsuyoshi Nishioka was granted his unconditional release Friday, making him a free agent. Nishioka requested his release, absolving the Twins of their 2013 financial obligations, which included a $3 million salary or a $250,000 buyout. "I would like to thank the Twins organization for helping me fulfill my dream of playing in Major League Baseball," Nishioka said in a statement. "I take full responsibility for my performance which was below my own expectations. At this time, I have made the decision that it is time to part ways. I have no regrets and know that only through struggle can a person grow stronger. I appreciate all the support the team and the fans in Minnesota and Rochester have shown me. Arigatou gozaimasu [Thank you]." The 28-year-old batted .215 in 233 at-bats over two seasons. He spent most of the 2012 season at Triple-A Rochester.
