Giants Lose Pitching Coach J.P. Martinez to Braves, Creating Vacancy for Vitello

Vitello now faces a pivotal hire after a staff that produced top-10 pitching results in 2025 lost a key Spanish-speaking voice.

Overview

  • Atlanta announced Martinez as its bullpen coach on Friday, and he leaves San Francisco after serving as pitching coach in 2025 following four seasons as assistant under a deal that ran through 2026.
  • Reports indicate Jayce Tingler is set to join Tony Vitello’s staff likely as bench coach, though the Giants have not announced the hiring.
  • The Giants are weighing internal options to replace Martinez, with bullpen coach Garvin Alston and roving pitching instructor Ryan Vogelsong mentioned as candidates.
  • San Francisco’s pitchers posted a 3.84 ERA in 2025 (10th in MLB) and the bullpen recorded a 3.48 ERA (fourth-best), underscoring the stakes of the replacement decision.
  • Bench coach Ryan Christenson left for the A’s first-base job and third-base coach Matt Williams will not return, and Martinez’s departure further narrows the team’s Spanish-speaking presence to assistant hitting coach Oscar Benard and the expected addition of Tingler.
