Reds' Tony Santillan: Likely done for season

Santillan (back) is unlikely to return this season, Bobby Nightengale of The Cincinnati Enquirer reports.

Manager David Bell called it a "long shot" to expect Santillan to return from his lower-back strain this season. Alexis Diaz has emerged as the Reds' go-to option for saves in Santillan's absence.
