Please evaluate this trade

I just made this trade proposal and it was accepted......

9 team roto redraft 5x5 with expanded rosters

210 start max
8000 AB max


I give Soler

I get Archer

I am having buyer's remorse.....but I needed a solid starter to help lower my terrible era of 4.1


With the AB limit, I need an empty slot or 2 every day in my offense

Is this a good trade? Which side wins?

Also, is Soriano a good stash for saves? Or if he signs, will he be a setup guy?

Thanks for any advice!
