Athletics' Yacksel Rios: Placed on 15-day IL

Rios has been diagnosed with Raynaud's Syndrome and was placed on the 15-day injured list Friday.

Rios had surrendered a whopping seven earned runs over just 1.2 innings (three relief appearances) since being promoted to the A's bullpen June 20, and he left his most recent appearance Wednesday after just three pitches complaining of numbness in his right index and middle fingers. He might be sent back to the minors whenever he's healthy enough to pitch again, but there's no timeline for his return to the mound.
