I love the story of John Paciorek (His brother Tom was a local Mariner hero of my youth....yes, we had to stretch for hero's here in the NW in those days, lol). He is a great trivia question as arguably the greatest 1 game performer in history. Here is a link to his Wikipedia -

He went 3/3 with 3 singles and two BB's in his only MLB game. There have been several 1/1 days of one game performers, but 3/3 is the best. This is the only card I could find for him -
