For sure. The Athletic story does a good job discussing the fact that almost any player can be "hurt," but sometimes the player and team don't always agree about whether an IL stint is necessary. But we also don't know. Maybe he was hurt. Or maybe he was hurt just enough that in July he simply would have missed a few days w/o going on the IL - we have certainly seen the Phillies go a player short for as long as 5 days or a week in those situations before - but given the timing and team needs this year it was a no-brainer.
But, per the Times (and that's a free link FYI):
The investigation into the Mets began when an anonymous whistle-blower sent the commissionerâs office a letter that said the teamâs general manager, Billy Eppler, had put at least one player on the injured list this year even though the player was not injured.
The commissionerâs office does not know who sent the letter. Among the possibilities is one of the Metsâ trainers, according to one of the people familiar with the matter. At least one of the trainers is said to have acknowledged to others this season that he was concerned that the team was breaking the rules because a player who was healthy was put on the injured list, according to the person.
