Lotta variables here, and i don't presume that Holds is a category, so Zumaya is a non factor in this trade (plenty of good setup men out there).
So you're talkin Rios and Soriano for Kershaw.
I'd like to see the rest of your staff, but my instinct on this one is that it's a no go. As much as i love Kershaw and his long term value (i have him in both my leagues...ouch on yesterday's start!) Rios is a great speed option with Power upside (knocked one tonight) and Soriano is a good RP to build on. You can't win Saves w/ one closer...so you either punt saves and probably steals and do this deal, or you try to go get yourself a real RP.
Good luck and please help with mineviewtopic.php?t=410770
