Researching 1975, we recently came across the Met debut of lefty reliever Tom Hall. “The Blade” was acquired from the Reds in an early-season trade and joined the Mets in St. Louis on April 16 where he pitched two innings of scoreless relief while wearing road uniform No. 42 (Ron Hodges, for whom the Mets had likely been carrying the 42 jersey, was doing a minor-league tour then). When the Mets returned home two days later, Hall was issued No. 19, which he wore for the rest of his year-plus Met tenure.
