No, it should be Yamaico Navarro. No question in my mind...
Of course it should be Lowrie. The Sox brass have sent every signal they possibly could this offseason by shopping Scutaro aggressively that they think Jed Lowrie should take over the shortstop position in 2011. If he can't, Jose Iglesias makes one heck of a fallback option, but Lowrie is clearly Plan A.
They actually have some nice depth in short right now between Lowrie, Iglesias and Navarro. We already know about the first two. I know everyone always underestimates the heck out of Navarro but he's a viable option who could be ready to play by midseason, and the fact that he's blocked five ways to Sunday kinda reinforces my point about depth. When you're stuck behind guys who are as talented and as ready as Lowrie and Igelsias, it's time to get traded, so I expect to see him shopped for an established relief arm before the end of the offseason. If Scutaro's moved, he might crack the roster as a utility guy, but I suspect he'd be more valuable to another team.
I could see the Royals accepting a deal that brought him over, there are other teams smarting at short who wouldn't mind giving a 23 year old shortstop who has a solid half year of AAA under his belt a chance to impress them too. And that's assuming Boston would mind. So in my mind, we have 3 young shortstops in that mix any one of which could turn into at least an above average player, that can only be a good thing.
