Ciriaco is an interesting case. He is really a very good fielder but since he has been moved around quite a bit it seems that he is not quite solid enough in any one spot while maybe being one of the best multi-position, utility infielders anybody ever heard of. Very rare for a guy to look totally competent for a few games at least at three infield positions. Ciriaco is a little weak at 3rd but can look very comfortable for short stints at 2nd and SS and can play 3rd as well.
As for his hitting, it would just be hard to trust him up in the lineup. He does not walk at all, prone to K and prone to chase pitches that don't even begin to look like they are going to be strikes.
I would think he would be a terrific bottom of the order hitter, batting 7th or 8th, maybe 9th, capable of stinging the opposition and having enough speed to allow the Manager to turn him loose. You can already see what happens with speed guys at the top of the order when the Manager believes he has a heavy hitting lineup. The speed guys basically stay pinned to their bases waiting for the heavy hitters to drive them around.
If the Sox had a really strong lineup I would love to see him bat 8th and play SS possibly platooning at SS in 2013. If he were to platoon at SS he would also be a utility infielder for the Sox. I could also see the Sox giving him the SS position for 2013 if the alternative were Aviles.
Unfortunately I think Iggy is going to get passed over. I have thought that all year as much as I hate to see it happen because I really like him. Iggy really needed to step up and show that he could be the guy for 2013 and that has just not happened. By the time 2014 rolls around, then the Sox may not be able to wait longer and Iggy might be traded at that point.
