According to MLB.com's Bill Ladson, the Nationals released Wily Mo Pena today. Pena refused his assignment to the minors after opposing teams chose not to claim him off waivers. Now that the Nationals are on the hook for his $2MM salary, he might be able to find a job somewhere.
Pena, 27, came to the Nationals in August of 2007 from Boston for Chris Carter. He had a nice initial stint with Washington, and signed a contract in December of that year. But 2008 was a lost year due to shoulder problems.
