Crazy Dojji Theory Time, but what with the state of the lower echelons of this bullpen, I wouldn't mind seeing Hall tried on the mound again in a no-pressure situation.
Basically I really liked what he managed to do and think he might be able to repeat it. He did a lot of what people pull their hair out trying to convince a pitcher to do -- kept away from the middle of the plate, kept it low, hit his spots at 89, and induced 3 ground ball outs, that starts to hover around the fringes of actual usefulness, especially when you're talking about pitching in relief. It went beyond the novelty of having a position player pitch to the point that Hall actually looked good out there (I know, I know, it was the Royals, but still). My eyes might be tricking me but I even thought I saw his fastball move a little towards the end of his inning

Two of those outs the catcher isn't even moving his glove, the third is a perfect 0-2 pitch on the outside corner where the hitter has to go get it and probably hits it on the ground.. Again, pitching coaches tear their hair out trying to get that from a lot of young kids.
It's not like we really have a great deal to lose, he's on the roster either way, and you never know if we could wind up in the kind of situation that had Javier Lopez in right field a couple years ago -- having a guy who could come in from left field, retire one righthanded hitter, and then go back into left field, could potentially be useful. Being able to wrangle having 13 pitchers and 13 players on a 25 man roster could also come in handy in some of the crazier games you encounter in a regular season.
Ehh, it's just a vagrant thought. I put it out there mostly so I can have said it somewhere so I can move on from it, so take it FWIW.
