more jeopardy “one hit wonders”

after harvey’s monday performance i obviously thought he might be a 10+ game winner, yesterdays game proved my prediction incorrect. who would you say are other 1 game winners who had a very strong first game but didn’t go on to win a second game.

https://j-archive.com/showplayerstats.php?player_id=13898 - i remember thinking she would be on for a long time. however she lost her 2nd game to a very strong 2 timer bryce hwang. unfortunately she didn’t compete in the CWC for 37/38 players.

i’m sure there are many others though. who are some other ones?
