Ben Clemens at FanGraphs takes a long look at why Francisco Lindor went into a slump this year. His conclusion is positive:

That’s not to say nothing has changed; those barrel and blast rates really do matter, and a downturn in top-end production makes the normal ebbs and flows of Lindor’s game look worse. But for the most part, Lindor has done what he always does — put a ton of balls in play without overwhelming power — and gotten the short end of the stick. This isn’t a dramatic change in his game, but rather the ugly downside of a volume-based offensive approach combined with a small but real slump in contact quality. That’s small consolation for a ravaged New York roster, but it bodes well for the rest of the season — and the rest of his 10-year contract, to boot.

While I don’t disagree, my go-to explanation for slumps like this is a minor injury. So Lindor could have some minor issue that allows him to continue playing, but robs his contact quality. With all the other injuries, the Mets were not in a position to give him ten days off to heal. I suspect if this is true, we won’t find out until the end of the season.
