I really, really think a lot of you guys are overvaluing Iglesias's numbers last season. He was 21 and in AAA ball. Give him 3 more years of experience like everyone else in AAA ball, and I guaratee you that he's OPS'ing around .750, which is really all we can ask from him.
He's not going to be a production bat, but his glove up the middle is going to save a whole lot of runs.
I can see Jacobs being ranked higher than him, and I can see that for Bogaerts as well (personally, I think WMB and Bogaerts should be the top 2 in our system), but I think a lot of people are dogging Iglesias because of a bad season. You have to look at guys like Jacobs and remember that he is 20 and is playing in A ball. During his brief, brief stint in A Ball (13 games, 48 PA, 40 AB) at the age of 20, Iglesias OPS'd .958. He's just had a bit of a problem with pitch recognition, and that's something that he'll gain with experience.
