I continue to be intrigued by the Twins 40-man roster. In hindsight, it appears a near certainty that the Twins were looking for a way to clear space for Garlick before the season started. Apparently, they were counting on moving a pitcher or two off the 40-man, either by DFA or placing them on the 60-day IL, or by trade. They have since designated Cotton to make space for Garlick, but if/when they need another catcher, they will have to make room.
I'm also pretty sure two pitchers that are in St. Paul (Minaya and Smeltzer) would be on the staff if they were on the 40-man roster. I think there are DFA candidates on the 40-man, but with the coming cut to 13 pitchers, the Twins probably don't want to promote someone and then risk that guy or someone being claimed within two weeks.
Certainly, other teams have the same issues. Having two catchers on the 40-man and so many pitchers just does make it tougher for the Twins to maneuver than most.
