The Twins have released Tsuyoshi Nishioka at the player's request.

The 28-year-old spent two disappointing seasons with Minnesota.

In a strange move, Nishioka becomes a free agent and the Twins are no longer on the hook for his guaranteed salary. He waived his right to his $3 million salary for the 2013 season and 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. "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."
