The Mets went through some dark periods in their whirlwind 2021 season. One of those dark times was a stretch in May when the Mets went from having a mostly-healthy team to a completely decimated lineup within the span of about a week. For a little while it seemed like it was quite literally every day the Mets would wind up with another player or three on the IL, and it got to a point where where they had nearly 20 players on the IL at one time.
Things got so bad that the Mets had to scrounge up names from anywhere they could find them just to field a team.
