Just happened in the Two Man Band league.
My '77 Tom Seaver, used in relief only for 90 innings, went 14-10, 3.10 with 30/32 saves
Runner up was '63 Koufax at 24-6, 4.96 with 288 innings
Third was '68 Gibson at 22-8, 5.10 with 236 innings
Notably, my Seaver didn't win the Fireman award. Squeezed out by '24 Babe Adams with 0-1, 3.82, 36/40 Saves and only 33 innings. No idea why.
