While Kahnle walks a ton of hitters, he has a 14 inning scoreless streak going and will become a FA on Monday, if we don't add him to the roster.
I'd say let's keep him.
I've given up on hopes that Crawford, Oviedo or Sandoval can help the pen out, when they return, and other AAA options look scary, so why not?
Other 40 Man options: Bennett, Anderson & Gamboa- currently starting and Kelly or Eduardo Rivera.
Other non 40 AAA options: Sansone & Burgos (starters) and Bastardo, Keller, Song, Olds, Sweet, Martinez & Webb (Uberstine has begun his rehab.)
Whitlock is on the IL with a knee issue. Crochet does not seem like be joining the team anytime soon.
