As Bryce Harper ended his 32-year-old season with his lowest wRC+ since becoming a Phillie, his least amount of fWAR accumulated in a season where he played at least 130 games since 2016, and his lowest slugging since 2016, it was natural to think that Harper was entering the natural decline of a player aging out of their prime.
Dave Dombrowski said what he said at the Phillies end of the 2025 season press conference and it blew up in everyone’s face. Especially since the Phillies went about the off-season
like they were expecting Harper to bounce back.
Through 43 games of a fairly ugly 20-23 start, Bryce Harper has bounced back. He has his highest wRC+ since 2021, ten home runs, and has looked like one of the better hitters in the sport.
He has done that through some fun adjustments that might give us a sneak peak into how Harper might age.
There are players on the 2026 Phillies that look older (or might be off to a rough start) but there isn’t anything about Harper’s profile that looks like physical decline. His average swing speed is roughly the same as it was in 2025 and 24, his 90th percentile exit velocity is nearly identical, and his sprint speed is the same. He has put that together with some approach adjustments.
Harper’s approach over the last few seasons relied on being aggressive early or in advantageous situations, as he saw fewer and fewer fastballs. As the count gets harder and harder, Harper has relied on his pitch recognition to make him a tough out. This is why Harper has spent the last several seasons with a 33% or higher chase rate but consistently working walks.
He is still working with an aggressive approach, a chase rate of 35.9%, a first pitch swing rate of 51.4%, and getting his walks in. However, he has leveraged this into making more contact.
The strikeout rate went from 20.9% in 2025, slightly above league average, to 16.9% in 2026. He has done that without cutting back on his swing so it had led to more raw power. His slugging has gone up 45 points in this span and he already has 20 extra base hits.
It has not led to a higher average or on base but that could be coming. Harper has his lowest BABIP since 2016 and theoretically, making more contact while maintaining similar physical indicators should make him primed for progression to the mean.
The biggest trend for Harper has to be with how he is trying to handle velocity. It hasn’t shown up in results yet but he is trying to do something very different than in the past.
Here is Harper’s whiff rate against 95+ mph from 2022-25
- 2022- 27.3%
- 2023- 28.2%
- 2024- 27.2%
- 2025- 26.0%
In 2026, Harper has cut that down to 12.3%, which has helped raise his zone contact rate and overall whiff rate. It has not fully led to production yet but that might be coming. His projected slugging against 95+ is higher than last season and is 94 points higher than his actual slug. That is probably going to turn around moving forward.
As Harper entered a bit of a crossroads in his career, he has taken that on by making adjustments while not showing any signs of slowing down physically. As the sample size gets bigger, it’s fair to say Harper has returned to the elite status that Dombrowski questioned back in October of 2025.
