While Keller has regressed slightly from his 2023 All-Star form, he’s still a very reliable force near the top of the rotation. In 32 starts last season, Keller recorded a 4.19 ERA, 150 strikeouts, and a 2.5 fWAR, all while posting his lowest HR/9 since 2022.

If Keller can post another season similar to his 2025 campaign, it would be huge for the Pirates’ rotation. It would do wonders for the Pirates to have another starting pitcher (besides Skenes) from wom they have a good idea of what to expect, especially considering their rotation this year will consist of plenty of new, young faces.

The Pirates no longer need Keller to be the superhero starting pitcher he had to be earlier in his career; they just need him to keep being someone they can rely on.

Leading a Young Rotation

Aside from being a consistent force at the top of the Bucs’ rotation, Keller’s impact will be felt far beyond his on-field production. The Pirates don’t just have a relatively young and experienced team on offense, but their pitching staff, as it stands right now, is going to include a lot of youngsters.

As a veteran, Keller’s job will be to lead these young arms, teaching them how to get acclimated to the major league level and the routines they will need to be successful. This is especially important because if the Pirates want any shot at succeeding in 2026, their rotation needs to perform like one of the best in the league.

Of course, as is the case for any player, the major league season can be full of ups and downs. These failures are more common among less experienced players, and mental toughness through rough patches can often make or break players long-term.
