It seems to me there are two ways of thinking about things. Baseball, as you know, is the one major sport where the playing dimensions between venues can be wildly different. Given that, I think you can either prefer neutrality and standardization, or you can choose to embrace the differences. There are limits to the latter — I don’t think anyone wants to see a stadium that makes a mockery of the contest, because you don’t have reasonable competition. But we haven’t gotten to the mockery point. So, personally, I like the quirks, even if they seem occasionally unfair.

Focus on that unfairness for a moment. If something were simply too unfair, it wouldn’t work. Fans wouldn’t support it. You couldn’t play a real baseball game with fences right behind the infield because the product wouldn’t be recognizable. I think there are certain features, currently, that approach the threshold without crossing it. Like, left field in Minute Maid Park approaches the line, because it yields a number of pretty weak home runs. It’s true, but without being out of control. On the opposite side of things, there’s straightaway center field in Minute Maid Park. If you want to conquer that, as a hitter, you have to hit the most difficult homer in baseball.

You might remember the Houston Astros announced some planned renovations. You might also remember the renovations have been delayed because the Astros themselves didn’t expect to make the playoffs. When people talked about the renovations online, they’ve focused on two things: removal of the flag pole and removal of Tal’s Hill. Those are worth talking about because they’re two of the most unusual features in any stadium around the league. Something that’s gotten a little lost, though, is the fence will be coming in as the hill goes away. In time, the center-field fence in Houston will be 409 feet away from home plate. For at least one more season, the distance will remain 436.

Four hundred feet, and another 36 feet. Longer home runs than this get hit, but it’s uncommon, even up the middle. This hasn’t turned people off, because this is just a small part of the Minute Maid outfield. It’s a part that also has a hill and a flag pole, and besides, center field is counteracted by left field. But that is a hell of a distance. Let’s play with an overlay, from the ESPN Home Run Tracker. What’s a pretty normal stadium? I think Dodger Stadium seems pretty normal. Here’s Dodger Stadium and Minute Maid Park.

There’s just so much extra space up the middle, and you can’t even see the hill in two dimensions. All the hill does is also make the center-field fence effectively taller. As a hitter in Houston, you want to pull the ball or you want to push the ball because the biggest part of the park is pretty unfriendly. Below, I’ve tried to represent the feeling as a hitter of standing in the box:

Because this is FanGraphs, we need to look at some numbers. How have hitters done with regard to clearing that center-field fence? This, again, is where the ESPN Home Run Tracker can come in handy, providing information going back a full decade. We miss the first few years of the stadium’s existence, but 10 years is plenty. So, I collected 10 years’ worth of major-league homers, and then I narrowed down to homers hit within a range of certain angles:

I selected the range from 85 degrees to 90 degrees. That basically captures the whole center field feature in Houston. I did this for all of the majors, calculating how many homers have been hit in the different home stadiums. I combined the numbers for teams who have had multiple home stadiums in the past decade. This table tells you what you probably could’ve guessed.

(Note: I excluded inside-the-park home runs. They’re fun, but they’re not relevant.)

Homers Between 85 – 90 Degrees, 2006 – 2015 Home Park Dingers Reds 127 Orioles 117 Indians 117 Rangers 117 Brewers 116 Dodgers 112 Pirates 110 Rockies 105 Nationals 105 Angels 98 Blue Jays 95 Braves 94 Phillies 92 Padres 90 Yankees 89 White Sox 84 Mariners 84 Rays 83 Twins 80 Cardinals 80 Cubs 66 Royals 66 Athletics 66 Red Sox 59 Marlins 55 Mets 53 Giants 50 Diamondbacks 40 Tigers 25 Astros 6 SOURCE: ESPN Home Run Tracker

Cincinnati has averaged about 13 of these homers a year. Baltimore has averaged about 12. The average park is around eight. Detroit is between two and three. Comerica Park also has a notoriously deep center field. Houston yields just six results, total. Almost one every two years. This is a difficult home run. It’s not an impossible home run, but it’s almost as close as it gets with things how they are.

The log of hitters and victims:

Among the things that stand out here, Oswalt has yielded two of these on record. One was hit by an Astro, meaning the other five were allowed by Astros. And there’s been just one of these homers in the past five years. It seems appropriate it was hit by George Springer, and here you can watch it:

That’s good. That’s a big home run. According to the data, it’s the longest of the six. But Upton hit my favorite. Because Upton found the deepest part of the deepest part, as if simply to prove his capability. He didn’t need to hit the most difficult possible homer. He chose to, and it turned out to be the only run of the game.

Michael Bourn thought Justin Upton had some nerve.

Upton made Bourn run as fast as he could for 100 feet. Upton made Bourn run straight up a hill. Upton made Bourn run for nothing. And then Bourn had to return to his position. I assume that caused an extended delay.

The hardest home run to hit has been attempted in Houston, and it’s happened once in the last five years. A home run to center in Minute Maid Park isn’t worth extra runs on the scoreboard, but it’s worth a little extra something at home or in the stands, which is kind of the whole point. Alas, before long, there will presumably be a different hardest home run, as this could be the final year of opportunities. There will always be homers to center in Houston, but it won’t matter as much when the fence is brought closer. Keep an eye out. Maybe two, when George Springer is up. A ballpark quirk is approaching the end of its life, and though there’s no shortage of ballpark quirks, there will soon be a shortage of this one. It’ll be missed… sometimes.
