The Cubs have the longest active streak of years without being no hit since Sandy Koufax's perfect game on 9/9/65 (45 years, this September). The longest streak of years w/o being no hit is held by the Phillies at 57 years.
The Cubs won their very first two games ever, and have not been under .500 ever since. They are the only team to be able to claim that. They are currently 10211-9658 (.514).
So there ya go Cubs fans. Feel free to toss that in Sox fans or Cardinals fans' faces. Just be sure to walk away before they mention 2005 or 2006.
