Alvarez's no-hitter was August 11, 1991 against the Orioles. It was the 7th win in a row for the Sox and they had won 15 out of 17. They were a game behind the Twins and closing.
I was 16 years old and convinced after the game the Sox were a team of destiny. A new park they were filling... Thomas having an MVP caliber season... Ventura hit a walk-off grand slam against the Rangers a week earlier and I had been at the game (best sporting event I have ever attended, including the black out game)... now you bring up a rookie who goes out and throws a no-hitter? No way this team doesn't win it all- it's a magical story.
Then they lost 15 of the next 17 and were 9 games out by the end of August.
