It is exactly 100 days until pitchers and catchers report, so I will use those 100 days to count down the 100 Most Significant Dates in Orioles history. There will of course be plenty of games on the list, although only if they have "significance" beyond just the game itself.   Tippy picking off three guys was unique and memorable, but in the end it was just one win in a championship season. So, here we go.   It's 100 days until pitchers and catchers report: #100 -- July 8, 1958
