I reviewed the list that accompanied your comment about Joe Mays (?)(!) and his great start yesterday against the Mickey Mouse Club...
A few thoughts. Cone's four wins came after he was traded by the Mets for clubhouse lawyer Jeff Kent and Ryan Thompson. Hill's wins came after he was acquired down the stretch from the Cardinals, I think. Sutton pitched for the disappointing Astros in 1982, I think, and was acquired down the stretch by the Wallbangers. John pitched for the pathetic 1982 Yankees (the first year I followed baseball from wire-to-wire) and must have won more games than just the 4, I suspect? So only Wolcott, who was a callup/reliever, and Mays fit into the category of "Where the heck did this start come from?" It makes it more amazing, as far as I'm concerned.
Murray is absolutely correct, only Wolcott really qualifies and I was just being lazy by saying "4 or fewer wins with their team". The other four played for two teams and here are their records:
Wolcott started game 1 of the 1995 ALCS for Seattle in his rookie year. He pitched 7 innings and only allowed 2 runs and scattered 8 hits (though 5 walks) in the 3-2 win over the Cleveland Indians and Denny Martinez. The Mariners lost 4-2 in the ALCS, but the Indians eventually lost to the Braves in the Series. Wolcott ended up 16-21 for his 5-year career and this win was his only postseason game.
