The Rays announced that they designated Hideki Matsui for assignment to create roster space for newly-acquired infielder Ryan Roberts. They now have ten days to trade Matsui, release him or place him on waivers.
The Rays signed Matsui to a minor league deal in April and he appeared in 34 games with the team. The 38-year-old posted a .147/.214/.221 batting line with two home runs in 103 plate appearances.
