Mariners Designate Casper Wells For Assignment

The Mariners have designated outfielder Casper Wells for assignment, tweets Greg Johns of MLB.com. The Mariners now have ten days to either trade, release, or outright Wells to the minors. If Wells clears waivers, he cannot elect free agency because he does not have enough service time and has not been designated for assignment before, reports the Seattle Times' Larry Stone (Twitter link). The Phillies and Tigers could have interest in the 28-year-old. Wells was a member of the Tigers until he was traded to the Mariners in the Doug Fister deal in July 2011.

The roster move means Jason Bay has made the team. The Mariners filled the open 40-man roster spot by selecting the contract of right-hander D.J. Mitchell, who was then optioned to Triple-A, according to Shannon Drayer of ESPN Radio Seattle (via Twitter).
