With Jerry Blevins on paternity leave, Paul Sewald becomes the Mets' reigning active roster iron man, having held his spot without interruption since May 1, 2017. Wilmer Flores was activated from the DL two days later and hasn't been off the roster since, though he was out most of September last year when he fouled a ball off his face, but space allowed him to stick around on paper. We're 39 games in and only 13 Mets from Opening Day haven't budged.
