It's a night game.
Here's a look at the numbers for these two nerds so far:
I calculated FIP using a 3.048 constant (that's 2013's constant).
At this point, Ramos is the only one who likes like he's had any degree of control. I don't expect he'd do any better than a 110 FIP- (so... *beep bop boop* 4.38 ERA, assuming league offense remains the same). But these other guys just can't seem to find the zone so far.
That said, if it was a half season we needed from the No. 5 guy, I'd say go Odo and just take the medicine.
Side question: Where's Jeff Niemann these days? Is he still out there in the ether?
