I had something very similar to this happen in one of my solo leagues.. My closer at the time who had an E duration in relief and no starter duration filled in for 1 game during a time when I had 3 starters injured & a bunch of AAA rookies called up to take their spots. Anyways, turns out he pitched a complete game shutout also & set the league record for strikeouts with 19 in the game. Nothing like it has ever happened since & he never even made another start (I mostly simmed that league due to time constraints). I was pretty shocked, but couldn't really complain seeing as how he was my pitcher
