Saturday night after the Mets fell to the Los Angeles Dodgers, the manager informed catcher Omar Narvaez that he would be in the lineup for Sunday’s series finale. Francisco Alvarez has turned an ankle rounding first base and though he remained in the game, the Mets thought it best to give their rookie sensation a break. It marked only the second time in the month of July the catcher had been written into the starting lineup and only the 11th time since he returned from a calf strain in early June. “I could have [played Alvarez] with the off day tomorrow,” said manager Buck Showalter.
