I feel like the Twins should bring in Ichiro to work with Buxton on gaining flexibility so he might be a bit less injury-prone. And maybe some stuntmen from the movies to help him improve his landings, rolls, and slides so he is a little less awkward on impact.
As for the plan to keep DHing him for another month until his knee is back to normal, I’m fine with it. The season is long. As Billy Beane said (paraphrasing), you spend two months seeing what you have and what you need, two months getting what you need, and two months playing with the team you wanted. This season seems like it can fit that blueprint pretty well, Buxton included. (Although most of the “getting what you need” may entail getting the Polancos, Kiriloffs, Lewis, Juliens…and Buxtons on the field.)
