Randy Messenger back to Japan

Pitcher Randy Messenger has reached agreement on a three-year contract extension to return to the Hanshin Tigers in Japan, his agent, Matt Sosnick, confirmed Tuesday.

Sosnick declined to reveal the terms of Messenger's extension, but previous reports have said he could earn a total of $15 million -- which would place it among the largest deals ever signed by an American-born pitcher with an Asian professional team.

Messenger, 32, pitched in the major leagues with the Florida Marlins, San Francisco Giants and Seattle Mariners from 2005-09. He received interest from multiple MLB teams this winter before electing to return to Hanshin, where he's pitched since 2010.

Messenger, a 6-foot-6, 260-pound right-hander, has a 39-32 record and a 3.03 ERA in four seasons with Hanshin. He's struck out 519 batters in 623 1/3 innings with the Tigers.
