Shinji Mori, though Mori ended up never playing a game with the Rays due to him tearing his labrum in 2006 spring training.
On December 15, 2006, Iwamura signed a three-year contract with the Rays worth $7.7 million, with a club option for a fourth year at $4.25 million.
2007 season
With his defensive position still undecided, Iwamura brought gloves for five different positions to his first year of spring training in the major leagues. However, he eventually won the starting third base job, despite the competition, and began his major league career at his natural position for the Devil Rays. Iwamura did not hit well in spring training but seemed to adjust quickly to major league pitching once the
2007 season began, hitting .339 in April. However, he was hit in the eye on a freak play while chasing down a fly ball and spent time on the disabled list until May 28.
Iwamura's bat cooled off somewhat when he returned. He finished his rookie campaign with a .285 batting average, 7 home runs, 34 RBI and 82 runs scored while serving mostly as the Devil Rays' leadoff hitter.
Iwamura's glove is made out of crocodile skin, a rarity in the major leagues (although some players wear gloves made out of kangaroo hide). Likewise, his bat, made by the North American sportswear company
