Reds' Lisalverto Bonilla: Heads back to minors

Bonilla was optioned to Triple-A Louisville on Wednesday.

Bonilla was enlisted to provide relief for a taxed bullpen, but he wound up allowing three runs in two innings Tuesday. Now that he's likely unavailable to pitch for a couple days, he'll head back to the minors. Devin Mesoraco (back) was activated from the disabled list to fill his roster spot.
