That's why the team has been dominated by left-handed sluggers for almost 100 years.
The one change you've seen is that the new stadium is much more friendly to right-handed sluggers than the old ones were. The "old" Yankee Stadium was 430 feet to left-centerfield before the fences were brought in during the A-Rod era to make room for the new monument area out there. And the original Yankee Stadium was 490 feet (yes, that's correct) to left-centerfield. Yankee Stadium had an irregular oblong shape to it for most of its history -- dating back to the time when it was laid out to accommodate a football field for the New York Giants.
296 feet
301 402 457 461 407 344 296 were the dimensions from the 1930’s to 1975.
