Cheng is hitting .154 with no XBH after hitting for the cycle. His OPS is going to slowly head back towards 725. There's no help coming from him. I don't think there's anyone at AAA that can really provide an offensive spark. They are more "in case of emergency" types.
The two worst batters combining whiff and chase are Story and Duran. I don't know how you go about fixing Duran if he's not getting fulltime at bats. Story is what he is. There really isn't an inhouse replacement for him even if you move him to 2b.
Mayer and Anthony have also started off the season slowly. Mayer is to be expected. Anthony may just need a different slot in the lineup.
If there was one thing going wrong with the team, it'd be an easy fix. Right now: Crochet is less effective, Gray is out, Bello is his bad version, the bullpen is very weak, Narvaez can't hit fastballs, Story can't do anything, Mayer can't hit, Anthony can't hit or throw, Durbin can't get balls beyond the IF, Duran can't hit and IKF is IKF.
