We have trivia questions on the Astros broadcasts, so here's the one from today:
What three New York athletes in the four major sports have had their #7 retired?
Mantle jumps to mind and I believe the Giants football team has retired # 7 although I couldn't tell you the name of the player. I think the Mets only retired Casey Stengel # 37 (that's why Keith Hernandez couldn't get it),and Tom Seaver #41, as well as Jackie Robinson #42. Gil Hodges' number is also retired, but I can't think of it.
That's as far as I can go. I'm thinking Brooklyn Dodgers or th baseball Giants before the move west, but I don't believe they've retired 7.
I don't think it's the Jets or Knicks have retired # 7, so it might be a hockey team.
BTW, the most common number retired in baseball is 4. In the early days of numbered jerseys around 1929 players wore the number that corresponded to their spot in the batting order. That's why Ruth is 3 and Gehrig is 4. $ is the most commonly retired number in baseball.
