That's an...interesting deal. Not that Gathright doesn't have value as a defender and a stolen base threat, but the Royals are struggling to find live arms to start games and Howell, recent shoulder soreness be damned, was still a young arm that might have been worth keeping around. Does Gathright go to left, or does he take center field and push DeJesus/Costa out to the corner?
I imagine Gathright becomes a fourth outfielder, pushing Kerry Robinson off the club. Personally, I think if a club offers anything of value for any Royals pitcher, it's probably worth accepting.
