# What is the average Left Field vs. Right Field fence distance in MLB?

All 30 parks. Make assumptions.

I'm thinking if the Right Field value is quite a bit lower, THAT is the reason why left handed hitters “hit better” with low and inside pitches – something announcers oft repeat over the decades but no one has ever yet explained why (in my experience) and the interwebs are withholding the information just to mess with us, so we'll have to solve it for ourselves.

According to this graphic, as of 2014, the average Left Field wall sits about 331 Feet from Home Plate, while the average Right Field wall sits about 328 Feet from Home Plate. So basically they are about the same distance, I wouldn't think it'd give either side much more of an advantage.

The MLB does state that:

The distance from home base to the nearest fence, stand or other obstruction on fair territory shall be 250 feet or more. A distance of 320 feet or more along the foul lines, and 400 feet or more to center field is preferable.

• Muey perfecto El Hefe! That is such a great graphic. I'm not seeing the avg. numbers you gave (assume you did it) but the one little graphic far left shows a 45' -vs- 51' foot variance between L/R. I should think 6” is a big deal on the foul lines. Also, there seems to be a LOT more opportunity looking just beyond that 302 right and 310 left field shortest point (on the one main graphic.) Looking at that, I would MUCH rather be a left-handed hitter in the MLB, and to my mind this explains clearly why a pitch thrown inside and down is more advantageous to a left handed hitter than a righty.

Here’s some data about distances for every ballpark

Most of them are very close to 330 feet down both lines, so I think that’s close enough to the average.

However, The distance to the left field and right field foul poles only tells a small part of the story. You also have to consider the distances to the power alleys, since more balls are probably hit in that direction then right down the line anyway. But, on the one hand, a shorter fence does make it easier to hit a home run, but on the other hand, a further fence gives more room in the outfield for balls to fall in or split the gaps for extra base hits (fielders have more ground to cover). I think a lot of this stuff cancels out, so I don’t think the distance to the fences really has anything to do with whether lefties “ Hit better” than righties, in the context of this discussion.

I’m not sure why, but if you look at how the average lefty swings the bat versus the average righty, there appears to be some differences. Lefties, on average, tends to take “longer swings” (or at least that’s how it looks to the naked eye). There is probably more data out there somewhere now that bat speed and swing paths are tracked and measured. But a longer swing would allow a lefty to get the barrel of the bat down to a lower plane than a right handed hitter would, on a low inside pitch. Therefore, I can see why a lefty might do better on a low inside pitch than a righty would. It’s just a matter of being able to reach that location with the sweet spot of the bat, and has nothing to do with fence distances.
