The difference between the 2019 edition of the Cardinals and the 2020 version will hinge on quite a few factors. Continued excellence in the bullpen, on the bases, and in the field will obviously play a part. The health of the starting rotation and their ability to paper over any injuries is going to be a factor. More than any other facet, the easiest way to gain ground is with the offense. As we saw last month, the offense made some strides in subtle ways. For instance, they improved their league-wide standing in contact percentage, swinging strike percentage, and walk percentage.
