Mookie Betts' season-long slump has been completely baffling to everyone involved. Fans don't know what's wrong, Dave Roberts doesn't know what's wrong, and even Betts himself doesn't know what's wrong. As he said a few weeks ago, "I've done everything possible. It's just kind of the same result. I'm out of answers. I've done everything I can do. It's up to God at this point."
Like Betts said, it hasn't been for lack of trying. Roberts has shuffled him around in the lineup and sat him a few times; Betts was still working on his swing when he was away from the team and attending his stepfather's funeral in Nashville; and more recently, former Dodgers and Red Sox teammate JD Martinez even took a trip out to LA to advise.
