Brandon Nimmo has never been the type of hitter fantasy managers draft expecting huge power. Even at his best, his value has come from doing a little bit of everything: getting on base, hitting for a respectable average, scoring runs, and chipping in enough home runs and stolen bases to make him a well-rounded fantasy contributor. But there is something particularly strange about Nimmo’s 2026 season.
The surface statistics suggest that the 33-year-old outfielder is having a mediocre power season, and a mediocre season all around. The underlying numbers suggest almost exactly the opposite. Through August 26, Nimmo is hitting .259 with a .326 on-base percentage and a .416 slugging percentage, along with 13 home runs, 49 RBI and six stolen bases. His 13 homers are particularly disappointing when compared with what he has done over the past several seasons. He hit 24 home runs in 2023, 23 in 2024, and then established career highs with 25 homers and 92 RBI in 2025.
With roughly a month remaining in the regular season and the fantasy playoffs upon us, Nimmo has just 13 home runs. That looks like a significant decline in power. But the Statcast data tells us there is much more going on here.
Nimmo’s Power Potential Is Lurking
The easiest way to understand Nimmo’s season is to look at the gap between what he has actually produced and what his quality of contact says he should have produced. Statcast data can help us easily do that.
Baseball Savant currently gives Nimmo an expected batting average of .280 compared with his actual .259 average. That 21-point gap is significant, but the slugging numbers are even more glaring. Nimmo’s .416 actual slugging percentage trails his .470 expected slugging percentage by 54 points. Among qualified hitters, that puts him among the biggest negative differences between actual and expected slugging percentage in baseball.
In other words, Nimmo is hitting the ball hard enough. The results just haven’t followed. That matters for fantasy managers because expected statistics aren’t based on reputation or projections. Statcast’s expected metrics use things such as exit velocity and launch angle to estimate what should have happened based on the quality of the contact. Expected slugging percentage, in particular, gives us a way to identify hitters whose actual power production may not accurately reflect their underlying contact quality.
He currently ranks at least in the 84th percentile in five important Statcast categories: expected batting average, expected slugging percentage, expected wOBA, average exit velocity, and hard-hit rate.
That’s an odd combination for someone sitting at a .259 batting average and .416 slugging percentage, and it shows that the results haven’t matched the expectations. His average exit velocity is around 92 mph, placing him comfortably among the better hitters in baseball, while his hard-hit rate is above 50% (50.7%, the best of his career). Those numbers aren’t just good compared with Nimmo’s own history; they are good compared with the entire league.
Nimmo’s barrel rate has climbed to 10.1%, according to Baseball Savant, compared with 8.8% in 2025 and 9.2% in 2024. His barrels per plate appearance have jumped to 7.0%, also comfortably above his previous career levels (5.1%). That is not the profile of a hitter whose power has disappeared. It is the profile of a hitter who has great contact but has not seen the results.
Home Runs Have Been Nimmo’s Kryptonite
This is where the comparison with Nimmo’s recent history is interesting. After hitting 16 home runs in 2022, Nimmo exploded for 24 in 2023. He followed that with 23 in 2024 and then 25 last season. He had become a relatively reliable source of 20-plus home run power while also providing a solid batting average and on-base percentage.
So far in 2026, he’s on pace to finish well below that range, but there isn’t much in his performance to suggest that he has suddenly become a 13-homer hitter. His expected slugging percentage is .471. His expected batting average is .280. His expected wOBA is .355. And his hard-hit rate and average exit velocity remain among the best numbers of his career.
That doesn’t mean Nimmo is guaranteed to suddenly hit 10 home runs over the final month of the season. Some hitters consistently outperform or underperform their expected numbers because of things like batted-ball distribution, speed, park effects, and other factors. But a 54-point difference between actual and expected slugging percentage is hard to ignore. His home-run-to-fly-ball rate is 9.0% this season, six points lower than last year and almost 4.5 points below his career average. Bad luck has definitely played a part.
The Batting Average Could Also Improve for Nimmo
The power discrepancy gets most of the attention, but Nimmo’s batting average may be just as important. His .259 average is not awful, but it is significantly below what his contact suggests. His .280 xBA ranks in the upper tier of the league, and that 21-point difference is another indication that his current batting average is due for correction.
He hit .274 in both 2022 and 2023 and .292 in 2021. Even last year’s .262 average was perfectly serviceable given the additional power he provided. A return toward the .270 range over the final month would not be surprising if his expected statistics begin translating into actual results. And if the batting average rises while some of the missing power finally arrives, Nimmo could finish the season looking considerably more like the player fantasy managers expected to roster, and someone who might be on a lot of waiver wires.
Fantasy Managers Should Still Start Nimmo Confidently
Nimmo’s numbers are telling us that his .259 average and .416 slugging percentage aren’t representative of the hitter he’s been this season. His expected statistics, exit velocity, hard-hit rate, and barrel rate all paint a much more encouraging picture. Thirteen homers after hitting at least 23 in each of the previous three seasons is a massive decline. But with his current quality of contact, there is still time for that number to move considerably closer to his established level.
For fantasy managers thinking about the playoffs, that’s the opportunity. Nimmo may not suddenly turn into a 30-homer slugger right now. That’s not who he is. But there is a very good chance the final month of 2026 looks more like the Brandon Nimmo we’ve seen over the past few seasons — and considerably less like the hitter who has produced just 13 home runs so far.
