.367 -- Highest career batting average (Cobb) I think this got rounded down to .366 a few years ago due to some scoring reconsideration. But, as kids, it was always .367! 56 -- Joe D's "The Streak" .406 -- Last .400 season. Teddy Ballgame in 1941 12 perfect innings and a loss -- Harvey Haddix. Do you know how the game ended? It's a cool story. Kind of an oddity in itself. Walt Dropo -- not sure what about Dropo is uniquely significant. 7 (This one may be a bit ambiguous, but I think you'll get it.) -- For the longest time I was stuck on Mickey Mantle's uniform # but then realized you probably meant Nolan Ryan's 7 no-hitters.
