This one is a close race. Starlin Castro has the potential to be a great SS, but right now, I would want Alexei Ramirez just slightly more than Starlin Castro.
Now we didn't get to see Castro for a full season, but he did accomplish some impressive feats. He hit .300 as a rookie, and who could forget his debut. But Alexei has more to love when it comes to fantasy baseball.
A line of 85-20-85-15-.280 isn't too far from possible for Ramirez. He has shown improvement over the last few years and if his numbers keep trending like they are he could very well be one of the top five shortstops in all of baseball. I just like his overall 2011 possible potential better than Castro's.
However, if I was going to draft in a keeper league, I would no doubt choose Castro a little higher. He is almost a decade younger than Ramirez and will most likely hit for a better average, steal more bases and possibly score as many runs as Ramirez in 2011.
Right now, Alexei is going in the Top 100 and the seventh best shortstop, while Castro is 11th in the 150 range. I'd take them both right at about where they are being draft, I may even reach a little for Castro.
