or ones run by Billy Beane (read: smart ones) don't actively groom players for this exact role. That 25th roster spot should be one with maximum flexibility, and a backup utility infielder who could pitch to a specific type of situation (righty/lefty matchup, flyball/groundball, etc..) would be a serious weapon, even if he sat below the mendoza line.
Seems odd that there aren't no-hit players with reasonable gloves being prepped for this kind of role.
Or maybe I have it backwards...maybe the fringe bullpenners should be taking fielding and conditioning a bit more seriously at the high minors. Work on one pitch, and two glove positions.
