You can mention Chris Sale as much as you want, this is one of the top run prevention units in the league so far. That is a fact. What isn't a fact is what Chris Sale may or may have not brought to the table. Let's not deal in what-ifs, let's deal in facts. The fact is the pitching infrastructure of this team is miles better than it was last year, as the team has turned from one of the worst run prevention units in the league to one of the best, under Breslow and the pitching coach he brought in . The rest is noise.
