The Mystery Met is clearly wearing #48. Joe Nolan is wearing #35 in the pic above, but according to Baseball-Reference he also wore #48. Nino Espinosa wore #48 in 1974 and then Randy Tate in 1975, but could this be Nolan in spring training '73? Nolan didn't make any more appearances for the Mets after those four games in '72 but he was still in the Mets organization through April '75.
