For all the signs that the White Sox haven't quite lived up to the preseason expectations they laid out during spring training, they've won five of their last six games — with three walk-off wins in the last seven days — and could reach .500 against old mate Chris Sale on Friday.
Considering that on May 3 of last year they were already 11 games under en route to a 100-loss campaign, this would seem to signal some kind of progress.
Really, the best it can offer for the time being is a mystery: What is this team?
