I think one big misconception here is that if the Twins continue to be in contention, that call ups of top prospects are more likely. The reality is the opposite - if they are still winning the Twins will go with veterans that have been in the big leagues before. Nearly all prospects struggle when they first come up (even of Sano and Buxton quality) and a team fighting for a playoff spot is not going risk that. So, if the thing you want to see most is Sano / Buxtion in the big leagues, better pray for a big losing streak or injuries (neither of which I am doing).
