A's lose Sandy Rosario to waivers 12 days after trade

Twelve days ago, the Oakland A's traded a player to be named later to the Boston Red Sox for right-handed reliever Sandy Rosario.

Ten days ago, they designated Rosario for assignment.

On Monday, the Red Sox claimed Rosario off waivers, four days after the the player to be named later (right-hander Graham Godfrey) was shipped to Boston. And now the A's are down two right-handers and left with a $20,000 waiver fee in return.

Rosario struggled in four appearances with the Miami Marlins last season after posting a 1.04 ERA and converting 16-of-16 save chances for Triple-A New Orleans.

If you're keeping score at home, Rosario has been on four teams in less than two months after being claimed from the Marlins by the Red Sox on Oct. 17, traded to the A's on Nov. 28, designated for assignment by the A's on Nov. 30, and claimed off waivers by the Red Sox on Dec. 10.

Let's hope he didn't put down any non-refundable rental deposits during those two months.
