Diaz (hip) was not used in a save situation Sunday, and the Mets and Ryne Stanek blew the save in his absence.
Diaz did pitch Saturday and converted the save while throwing 22 pitches, but they didn't turn to him to cap off the series against the Cats. It's unclear whether he has aggravated his previous hip injury or if the Mets were just being cautious with Diaz.
