Which Pitcher to pick up ??

[SROSARIO324]

Have various options on waivers like Bartolo Colon, Patrick Corbin, Travis Wood, Jorge del la Rosa, and Andrew Cashner?
Is any worth picking up for Jose Fernandez or anyone else on my roster???? Wood and Corbin looking like the real deal after 4 starts and pitching in the national league helps their cause. Corbin obviously has more win potential.

How would you rank these pitchers ROS?????

I don't love any of them for the ROS but I would be fine dropping Fernandez and using that spot to stream. I think those guys can have solid games and I would be more inclined to spot start them rather than just pick one and hope they can continue this all year.
