Washington Nationals Name 30-Year-Old Simon Mathews Pitching Coach

The ex-Reds assistant signals Washington’s shift to an analytics-driven, youth-focused pitching program.

Overview

  • The team announced Mathews’ hire on Nov. 11, with manager Blake Butera praising his modern approach, perspective on pitching and player rapport.
  • Mathews departs Cincinnati after serving as assistant pitching coach in 2025 and previously working in rehab, a move Reds GM Brad Meador called a tough loss as the club works on a replacement.
  • His background includes roles at Driveline and Push Performance, a biomechanics-heavy skill set and fluency in Spanish that supports communication with a diverse staff.
  • Coverage anticipates changes to Washington’s pitch mix such as fewer four-seam fastballs, noting the Reds cut four-seam usage in 2025 and posted a 3.86 team ERA, their first sub-4 mark in a full season since 2014.
  • The hire continues the Nationals’ youth movement under Paul Toboni and Butera after a poor 2025 pitching season that included a 29th-ranked team ERA.
