Getz at least had a .700+ ops vs. RHPs in '12. So as an injury replacement for a couple games would work.
Giavotella is on his last shot as a Royal in my opinion. He does have good AAA numbers, but on the 20/80 scale, he only has one tool which is anything more than a 50, and that is the ability to hit for contact. That tool has not translated in his MLB ABs so far. Couple the lack of success with a lack of ability to play anywhere else on the field...and that he will be 26 in July...he is on his last chance.
The guy I'd watch for by the end of the season is Christian Colon. His #s improved last season, and he got to AAA at the end of the season. He can play 2B or SS, is a former 4th overall pick, and has drawn comps to Placido Polanco. I think he holds down 2B by this time next year...and maybe by August of this season.
