It should come as no surprise after the cringe-inducing knee-gouging events of Saturday's game that Aaron Cook will not be remaining with the Red Sox for now. With the sinkerballer headed to the disabled list, the Sox have now called up LHP Andrew Miller.

That's right. The Andrew Miller experiment is, sadly, back on.

With Miller's rehab assignment coming up on its limits, the Sox were in a situation where they either had to promote Miller or let him walk, so Cook's injury does come with perfect timing, if there is such a thing for an injury.

Unfortunately for the Red Sox, they're not exactly getting an upgrade in Miller. For all that he has managed 23 strikeouts in 11 innings down in Pawtucket, Miller still has no idea how to keep runners off the basepaths, offering up seven runs and 14 walks in the same period.

Miller has been coming out of the bullpen and will almost certainly continue to do so in Boston, but hopefully it's as nothing more than mop-up duty. Even with this bunch of arms that the Sox have, he's at the bottom end.
