As significant as Blake Butera’s hiring was – and, let’s be clear, it’s incredibly significant – there has been just as much interest in learning who will fill out the new Nationals manager’s coaching staff.

Given Butera’s almost unprecedented youth (at 33, he’s the youngest major league manager since 1972) and lack of experience (he never played, coached nor managed above Single-A), conventional wisdom said he would look to surround himself with older, more experienced coaches.

That’s partially the case so far, but not entirely the case.

The Nats are still in the process of hiring several more staff members, so we don’t know what the full makeup will look like yet. But while Butera has hired a more experienced bench coach in 50-year-old Michael Johns, his pitching coach (Simon Mathews) is actually only 30. And while the other three known members of the staff (Bobby Wilson, Sean Doolittle, Tyler Smarslok) all have some big league coaching experience, their ages range between 33 and 42.

“I don’t think we really set out to either hire for or not for experience,” Butera said. “I think what was first and foremost was that we wanted to bring in people who align with our values. We wanted people that would help hold each other accountable, come in with a tremendous amount of work ethic and make sure they were in this thing for the right reasons.”

The youngest major league manager in five decades is going to have a pitching coach even younger than him. One with a significant D.C. connection and a pedigree in modern baseball philosophy.

The Nationals have hired 30-year-old Simon Mathews as their new pitching coach, luring the up-and-comer from the Reds to work for 33-year-old manager Blake Butera.

Mathews, who first made a name for himself as one of the best pitchers in Georgetown history, spent this past season as Cincinnati’s assistant pitching coach, working underneath the highly regarded Derek Johnson. That’s his lone season on a major league staff, but that actually makes him more experienced than Butera, who has never played, coached nor managed above Single-A.

Mathews worked in the Reds organization for five seasons, the first four in the minors. He began in 2021 by implementing the club’s pitching program at its Dominican academy, then was rehab pitching coordinator in 2022. He served as assistant coordinator of rehabilitation and pitching initiatives from 2023-24, then earned his first promotion to the big leagues in 2025 as assistant pitching coach.

Cincinnati’s pitching staff has lowered its ERA and WHIP each of the last four seasons, from a 4.86 ERA that ranked 28th in the majors in 2022 to a 3.86 ERA that ranked 12th this year, and from a 1.389 WHIP that ranked 26th in 2022 to a 1.222 WHIP that ranked seventh this year. The Reds earned a wild card berth this season behind a pitching staff anchored by three homegrown starters in their 20s (Hunter Greene, Andrew Abbott, Nick Lodolo) who each finished with an ERA under 3.35 and a WHIP under 1.150.
