Who would you keep?

[Carnac]

Can keep 3. Can't keep any player drafted in first 3 rounds.

Best options

Chris Davis 1B 7th round
Starling Marte OF 16th round
Strasburg SP 10th round
Iwakuma SP 18th round

Davis....keeping
Marte....keeper as of now
Strasburg....keeper as of now
Iwakuma....considering because he would be an 18th rounder for me.

Should I keep Iwakuma over Strasburg? What would you do.

I try to trade Iwakuma and Strasburg for another nice bat. If I had to choose there is no way I keep Iwakuma over Stras.
