I did find it interesting. Hard to ignore the fact that you had two teams who aren't exactly crushing the baseball. The Cardinals and Reds leave the weekend as the teams with the lowest expected slugging (xSLG) in baseball based on their contact rates, their launch angles, and all the good stuff we can get from Baseball Savant.
The Cardinals' x SLG as a team is .372 (29th). That's not great.
The Reds' xSLG as a team is .365 (30th). That's worse.
The humidor is worth noting, but it's not really clear what help/aid/influence that's having for these Midwest towns. Heck, the humidors in Colorado and elsewhere are set for summer near Washington, Mo., and by default every summer St. Louis cannot help to also be set for conditions near Washington, Mo.
What stands out from this past series that the Cardinals went to Cincinnati, the salve for any offense, and didn't thunder away, didn't get their power going at Great American Small Park. That's of note, because it's not going to get easier this week as the Mets come to St. Louis at the big ballpark downtown. The Cardinals offense has gotten by. It hasn't gotten going. It hasn't yet shown a sign of getting hot.
