The Devil Rays signed infielder Akinori Iwamura on Friday to a three-year contract worth $7.7 million, with a club option for a fourth year at $4.25 million. "I am really excited and humbled by this opportunity," said Iwamura. "I look forward to being part of the Tampa Bay Devil Rays and wearing the uniform." In November, the Rays won the negotiating rights to Iwamura through the posting system that enables Japanese players to play in the United States with a high bid of $4.5 million. That bid, which is paid to the Yakult Swallows, topped both the Indians and Padres.
