When the Mets bring up a highly rated prospect, there's always the potential that he'll be the last player to wear whatever uniform number is assigned to him. Given that, the number should be chosen with care. So what number should Nolan McLean be assigned? I looked at the current numerical roster at https://www.baseball-reference.com/teams/NYM/2025-uniform-numbers.shtml The most suitable numbers that are unclaimed (and unretired) seem to be 21, 26, 40, and 45. I've seen photos of McLean in a number 13 Mets jersey, but that's currently assigned to Luis Torrens. Other good numbers are currently assigned to less prominent players who are currently inactive, such as 19 (Jose Siri), 29 (Jared Young), 30 (Hayden Senger), 32 (Max Kranick), 33 (A.J. Minter), 49 (Chris Devenski). I'd give him 30. It was the number that belonged to the only other Met pitcher named Nolan, and he turned out pretty well.
