On September 9, 2026, the San Diego Padres routed the Washington Nationals 9-2, and Jackson Merrill accounted for more of that margin than anyone else in the box score. The Padres outfielder hit two home runs in the win — on a day when the average big leaguer who played hit 0.18 home runs, that's a gap large enough to make Merrill a statistical outlier by a wide margin.
Start with the baseline: across every player who appeared in a game on September 9, 2026, the average number of home runs hit was 0.184 — meaning most players who took the field that day hit zero, and the ones who connected mostly managed just one. Merrill hit two. The gap between his output and that daily average produces a z-score of 4.56, which is the kind of number that, translated into plain terms, shows up only a handful of times across an entire MLB season for any individual player — roughly the frequency of a performance you'd expect to see once every few seasons, not once a week. Zoom in on Merrill specifically: he came into the game with 24 home runs in 143 games this season. Two in one night is worth roughly 8% of his entire season home run total, delivered in a single game against Washington.
Here's the honest limitation: Baseball Savant doesn't have per-homer exit velocity or launch angle logged for either of Merrill's two blasts, so there's no 112-mph reading to point to as the smoking gun for this specific game. What we do have is the shape of his season — a .295 on-base percentage next to a .431 slugging mark, with 143 strikeouts through 143 games. That's a hitter whose value is concentrated almost entirely in the power column rather than in getting on base via walks or contact quality. Two home runs against a Nationals pitching staff, in a game San Diego led throughout on the way to a 9-2 final, fits that shape: it's not a product of a lucky bloop or a bunt-and-run sequence, it's the outcome of an aggressive approach doing exactly what it's built to do on the nights it connects.

Merrill is 23 and in the second full season of his career, and nights like this one are rare even for him — a .726 OPS season built more on slugging than average tells you he's had stretches of quiet at-bats mixed with sudden power. San Diego is playing meaningful September baseball, fighting for playoff position, and a lopsided win over a rebuilding Washington club is the kind of game that pads a run differential more than it moves the standings on its own. Still, for a player whose season average sits at .245, a two-homer night is a reminder that the raw power tool is real, even when the overall batting line looks uneven.
The specific thing to watch over the next few weeks: does Merrill's .431 slugging percentage climb meaningfully by season's end, or does this game get filed away as a one-night spike on an otherwise flat power curve? With roughly three weeks left in the season, another multi-homer game — or even two more solo shots in his next ten games — would start to look like a real hot stretch rather than an isolated outburst.
Either way, the line now reads .245/.295/.431 with a two-homer night buried inside it — proof that a modest season average can still be hiding something loud.
