Nationals pitching prospect Sammy Solis is aiming to return in the "second half of May.," according to MASN.

Solis is recovering from Tommy John surgery, and was able to throw in extended spring training last week. Though he reportedly looked good, Solis remains a few weeks away from seeing game action. He's hoping to return at some point in May. Solis was a second round pick by the Nationals in the 2010 draft.
