Pick up a SP,RP Reliever for innings?

[Frappy]

Hello, I was toying with the idea of picking up a SP,RP reliever who
s been pitching well to help with innings and contribute a bit to some categories. 5x5 Roto 12 team standard and a 1250 IP limit. Im behind pace a bit in Innings and all non-closers are availible minus some guys like Zumaya.

I was thinking someone like a Jorge Sosa who has a 2.70 ERA with the cards in 16 innings of relief or Tomko who has been great in relief untill just these past few days. Any suggestions?

Edit: and I posted it here more on the topic of strategy then who to actually pick up. THats why I posted it in this forum.
Edit2:Actually I think Heilman would be a real good choice. He gets a good amount of work and has been excellent as of recent. His K/9 Is up there and he's been vulturing wins as of late.
