July 31st was supposed to be a day the Chicago Cubs upgrade their roster to put together a World Series run. Sadly, the Cubs hardly made any trade moves to improve the roster.

Andy McCullough of The Athletic (subscription required) recently gave the Cubs a solid grade of a ‘B’ for their addition of relief pitcher Andrew Kittredge to the bullpen. He noted the team's relief ERA (3.90) sitting middle of the pack at 15 out of 30 teams, but their 1.0 fWAR being 25th of 30.
