I like to see them adapting to the game in real time. My guess (without having actual experience) is that base stealing and the running game take extra time to learn how to master so they've spent their time practicing other things, like beating the shift, etc... I have seen instances this year where it didn't make sense NOT to attempt a steal. When being throwing out is not the worst outcome. Like when you are on first, there are 2 outs, and the next 2 guys on deck are both hitting around .200. In the particular instance I am thinking of (can't remember who it was) the batter got a hit that would have driven in the runner from second. Instead of a run generated, the next guy got out.
I also see people jogging back to first when the pitcher throws over indicating that he didn't have nearly a large enough lead. You don't need to actually steal the base to be effective. You can induce pitchouts, advance on the occasional bad throw to first, throw off the pitcher's (and sometimes the hitter's) concentration.
I think for a team like the Twins to succeed, they have to play all of the small games within the game well. That's how they will beat the teams that have more raw talent. They're doing a pretty good job this year with defense, working counts, using the whole field, experimenting with their RP usage (which is risky and maybe not a long term thing, but things are going well so far). I hope they start working on other tricks soon as well.
It's a fun season so far.
