The Twins farm system has 2 elite talents and 1 other top prospect that many want to declare off limits. After that there are prospects that are trending down (Meyer, Stewart, Thorpe and even Gordon until recently) or prospects that are viewed with skepticism (ABW, Gonsalves, Hu, Duffey etc...). It is kind of tough to make a high profile trade when you declare your top 3 off limits and the remainder are struggling or not convincing people that they can become a top 50 prospect. If you are going to make a big trade you need to be willing to part with top 100 (and more likely top 50) prospects. Two prospects fall outside of this grouping although there might be some skepticism regarding them. Kepler is looking really interesting but some are putting him into the untouchable list (difficult to make a trade with untouchables). Polanco just keeps producing but he doesn't get recognition nationally and is just barely cracking top 100 lists. Addressing the other concern. Why can't the Twins call up a player to fill hole (catcher or RP)? No farm system is stacked at every position. The Twins have already used the farm system to plug a hole in CF (Hicks), LF (Rosario), DH (Sano), SP/RP (May) and RP (Graham - Rule V). This is a pretty good payback from a farm system in one season.
