Rob Neyer would do these; even wrote a whole book of them. I was hanging out at BTF last nite (the Factory, not Backyard Tire Fire) and someone mentioned the Second Spitter Seinfeld episode. They said, ” They say the game was June 14, 1987, Mets/Phillies, and Keith had blown the game on an error. It turns out that the Mets played the Pirates that day and won 7-4 on with the help of a Hernandez homer.” I looked at retrosheet. Against Philly, he had a non-crucial error September 7th. He had one during a tie game vs Pittsburgh on the 18th, but that was at Three Rivers. I don’t think that Larry David or whoever wrote the episode cared about the historical accuracy of a midseason baseball game, but it would have been interesting if there was an element of truth to Newman and Kramer’s game description. I only checked 1987.
Is Seinfeld part of the Tommy Westphall Universe? I know that there is a tenuous connection between it and Mad About You. Maybe there’s a parallel MLB in that universe where Hernandez still won his MVP but blew that game.
