Interesting goings-on down on the farm for the Red Sox. Yesterday, uber-prospect (and not-signable-enough-even-for-the-Yankees) Craig Hansen threw four innings in a start for Boston’s Triple-A team. Stretching it out offers us a couple of scenarios. First, there is the chance that the Sox are making an effort to convert Hansen into a starting pitcher, which if successful could increase his value to the team, his value on the trade market, and his possible impact later on in this season (or next). The second possibility, which we find more likely, is that Hansen is being stretched out to gain arm strength, to learn more pitches, and to get experience in a wider range of situational baseball. Instead of closing games out in Pawtucket, and coming in and blowing guys away with one pitch, maybe two, Hansen will have to mix it up and learn more pitches. Guys will see him more than once in a game, and he’ll have to adjust accordingly. This is the kind of mentoring that we like, the kind of teaching that if deployed properly and carefully can diversify a system, that can conceivably turn a good player into a great one. We have no idea if Hansen will be an impact player or if his arm can withstand the stress of the additional innings, but it looks as if Boston is approaching this specific player with deliberation and intent, and we guess that is an attitude that pervades the system and applies to the teaching methodologies throughout the minors. Very encouraging.
