The Tampa Bay Rays have designated outfielder/designated hitter Hideki Matsui for assignment.

Matsui signed a minor league contract with the Rays on April 30 and was called up to the majors on May 29. In 34 games for the Rays this year, he hit .147 with two homers and seven RBI.

This season was Matsui's 10th in the majors, making him the first player in baseball history to play 10 seasons in Japan Pro Baseball and 10 in Major League Baseball.

The nine-time All-Star in Japan (1994-2002) and two-time American League All- Star (2003-04) has the most home runs (175), RBI (760) and walks (547) of any Japanese player in major league history.

Matsui is a career .282 hitter over 1,236 MLB contests with the Yankees, Athletics and Rays.

In addition, the Rays have added infielder Ryan Roberts to the active roster. He was acquired Tuesday night from the Arizona Diamondbacks in exchange for minor league second baseman Tyler Bortnick.
