I was going to write this last week, but life intervened. So this is not "this week in history" but instead "14 years and one week ago today"
If you were to ask most people what the best-pitched game in Diamondbacks history was, the answer would almost certainly be Randy Johnson's perfect game. And while I wouldn't disagree with designating that as the best regular season performance (Randy Johnson and Curt Schilling both had some incredible performances in 2001), there is another game that, according to Game Score, is the equal of Randy Johnson's perfect game, and it has been largely forgotten.
