If the ball isn’t smushed to an oval off the bat then we might have problems!
In my experience when solid/productive players aren’t producing, there is typically an underlying nagging physical issue. Doesn’t mean injury, just means he’s not playing at 100%. When you aren’t 100% you try and compensate and your mechanics and timing go out the window. If he and the brass think he’s well enough to play, then I don’t see any issues and imagine he will be fine soon. If he starts getting multiple days and misses more time, that may point to a short stint on IL to get back to 100%
