It’s been a good season for Aaron Nola. Especially in the second half, he’s looked solid and reliable; a comforting return to form, like a rerun of a favorite TV show. There is one thing that’s still plagued him, though, a thorn that he can’t quite pull out of his paw: the homers. The home run has seemed like an almost ubiquitous part of the Nola start. His 34 gopher balls surrendered are the most league-wide, tied with Jeffrey Springs, and one ahead of Shota Imanaga. The homer problem (the downtowner dilemma, the tater trouble, the four-bagger fretting), has gone on for far too long to be dismissed as happenstance. It is, unfortunately, as real as the Phanatic’s green fur. Case in point: I drafted this article on Friday afternoon, just prior to Nola’s start, hoping I wouldn’t have to rewrite any of it; it is now Saturday evening and I am rewriting it to account for the two homers he surrendered. That being said, what if he’s been at least a little unlucky?
Nola has allowed 34 homers this season, but per Statcast’s numbers, his expected number of homers allowed is 27.3 (that’s with the adjusted model, which accounts for environmental variables, and which we’ll use elsewhere in this article; it’s 30.4 if you’re accounting for trajectory only). That puts him at 6.7 homers above expected in 2026, second-most league-wide. Even if his actual homer total was identical to the expected, he’d still be one of the most-homer prone pitchers in baseball this season; he’d just rank fourth instead of first. Still, that might suggest that the homer problem isn’t quite as bad as it’s seemed in 2026.
Then again, if you look at the one pitcher who has a a greater gap between his actual homers surrendered and expected homers surrendered, it’s Springs, who’s allowed the same number of actual homers as Nola. And the pitcher who’s got the third-biggest gap in that regard is Imanaga. That stands to reason: the more prone you are to surrendering the sort of long ball that can become a homer, the more prone you’ll be to surrendering the sort of borderline ball that might become a homer and might not become one, with the vagaries of ballpark design and environment determining its fate. So while we can say that Nola’s been a little unlucky, homer-wise, I don’t think it’d be quite right to suggest that the gap between his expected and actual homer stats is purely or even primarily the result of misfortune. He really does have a genuine homer issue.
(It’s perhaps worth noting here that of all the pitchers who have allowed at least 20 dingers this season, Nola has the lowest percentage, 2o.6, of what Statcast refers to as No Doubters— homers that would be homers no matter which ballpark they’re born in. Compare to Imanaga’s 29.4%, or Springs’ 42.4%. I’m not convinced that it’s a terribly meaningful fact, but I do find it curious).
That being said, there is one way in which Nola is arguably unlucky: he plays half his games at the third homer-happiest park in baseball, per Park Factors, and the one most prone to allowing homers to the lefties who already have the platoon advantage over him. It’s not just the dimensions of CBP, either: per Statcast, Citizens Bank Park ranks ninth among MLB ballparks for extra distance added to balls by the effects of the weather, environment, etc.
I say this is arguably unlucky because this wasn’t really luck; he chose to resign with the team that calls Citizens Bank Park home. Then again, I suppose you could argue that luck was involved given that he had no say in where he was drafted, which eventually set up the sequence of events that led to him choosing to resign with the incumbent club. But that’s getting awfully philosophical. Speaking of philosophical, let’s imagine some hypotheticals.
Imagine an alternate world in which Nola pitches every one of his starts in Boston (perhaps a dystopian future in which only Boston remains, perhaps a world in which some sort of New England envy results in every ballclub directly copying the dimensions and environment of famed Fenway, it doesn’t matter). That hypothetical Boston Nola would have allowed only 15 homers this year. Now imagine if only Philadelphia existed. Most people, we can all agree, would be happier in such a world. But Aaron Nola would not: he’d have allowed 35 homers in this alternate All-Philly 2026, one more than he actually has. And that is the only park that would produce such an effect: place all his starts in any other ballpark, and he allows fewer gopher balls than the real Nola has. Citizens Bank Park is a wonderful place for everyone, except for Braves fans, Mets fans, and homer-prone pitchers.
As an example: take this homer Jake Burger hit against Nola in his first start of the season:
That’s obviously an unlucky break for Nola: just a few inches to the left and it would be foul, with no harm done other than some induced heartburn. But it’s even more unlucky than it appears: if it had been hit in any other ballpark in baseball, it wouldn’t have been a home run (although that’s by Statcast’s environment-adjusted model; per the trajectory-only model it would’ve been a dinger in 17 of 30 parks).
And this one, hit by Francisco Alvarez back in July, was even more unlucky for Nola.
It barely cleared the wall at CBP, and it wouldn’t have been gone at any other park. Even if we use the trajectory-only model, it still would’ve been gone in only two other parks.
But the most unlucky homer of all was probably this one, hit by Luke Keaschall at the Field of Dreams game:
If that game was played at any standard big league ballpark, that ball stays in the yard rather than finding a happy home in the corn.
Any pitcher in the league, of course, has similar stories, of homers that would’ve ended as harmless fly balls if the location had been different, or if it had been a few degrees cooler, or if the wind hadn’t been blowing in quite that direction. Betteridge’s Law of Headlines applies here: Nola’s homer problem isn’t the result of bad luck. Misfortune may have resulted in it looking slightly worse than it really is, but the underlying problem is real. But so is Nola’s return to form this season, and what he’s done for the 2026 Phils. We ought to feel lucky to have him.
