"John Smoltz has been released by the Red Sox, a major league source told FOXSports.com.

The move is not a surprise, since his contract was designated for assignment on Aug. 7. Smoltz will clear unconditional release waivers on Wednesday, at which point he will be free to discuss a new contract with any team.

The Dodgers, Marlins, Cardinals and Rangers have interest, sources have told FOXSports.com senior baseball writer Ken Rosenthal.

Smoltz, 42, does not intend to retire and is open to joining clubs as a starter or reliever, a source told Rosenthal over the weekend.

The Red Sox are now obligated to pay the remainder of the one-year, $5.5 million contract Smoltz signed in the offseason."
