Keppinger was something of a super-sub previously; I think the Sox would be best served if he did that again when Beckham returns. Let him start at third v LHP, and be the primary backup at 2B, 1B and DH, and let him pinch hit against LHP.
The universe is the practical joke of the General at the expense of the Particular, quoth Frater Perdurabo, and laughed. The disciples nearest him wept, seeing the Universal Sorrow. Others laughed, seeing the Universal Joke. Others wept. Others laughed. Others wept because they couldn't see the Joke, and others laughed lest they should be thought not to see the Joke. But though FRATER laughed openly, he wept secretly; and really he neither laughed nor wept. Nor did he mean what he said.
