MLB Pitching Coach Job Description

An MLB Pitching Coach owns the preparation and performance of a major league pitching staff. MLB.com's glossary lays out the core of the job: pitching coaches instruct their pitchers on mechanics, pitch selection and preparation, give them insight into the weaknesses of opposing hitters, often with the help of video, and can alter a pitcher's arm angle, his placement on the rubber or his pitch selection to improve performance or durability. During games, the coach assists the manager with decisions about the starting pitcher and the relief corps.

The group is large and never fixed. From Opening Day through Aug. 31, and again in the postseason, a club can carry no more than 13 pitchers on its 26-man active roster; from Sept. 1 through the end of the regular season, rosters grow to 28 players with a limit of 14 pitchers. Starters, setup men, a closer and long relievers each need a different weekly plan, and injuries and roster moves can leave the September staff looking different from the April one. The lead coach does not carry that alone: clubs such as the Reds and Twins also employ an assistant pitching coach and a bullpen coach, so the job is closer to running a department than to giving private lessons.

Game days follow a set rhythm. Before first pitch the coach meets with the starter and catcher on how to attack the lineup, confirms which relievers can work, and gives that list to the manager. Once the game starts, he watches from the dugout, talks with the bullpen by phone, and decides when a mound visit is worth spending. A visit is limited to 30 seconds, counted from the moment the coach leaves the dugout and is granted time, so the message has to be short: one mechanical cue, a change in how to sequence the next hitter, or a direct question about whether something hurts. The pitch timer, 15 seconds with the bases empty and 18 seconds with runners on base starting in 2024, also limits how long a pitcher can reset between pitches, which makes the pre-pitch routine a coaching subject of its own.

Between outings the work moves to the bullpen mound and the video room. Each club has 12 Hawk-Eye cameras around its ballpark for Statcast, five of them high-frame-rate cameras that focus on bat tracking and pitch tracking. Pitch tracking now covers data like spin rate, vertical and horizontal movement, release points and more, and the coach's task is to tie a change in those numbers to something the pitcher can feel: a grip that has drifted, a front side that opens early, a slider thrown with less conviction after a rough night. Analysts may spot the pattern first. The coach decides what the pitcher hears, how much of it, and when.

Trust holds the whole job together. A pitching coach has to give blunt feedback to a veteran with a long track record and settle a rookie called up that morning, sometimes in the same afternoon, and both have to believe the advice will make them better.

No license, certification or degree is required to coach pitchers in the majors. Clubs hire on baseball experience, a coaching record, and the ability to turn information into instruction that pitchers will actually use on the mound. As a rough guide, candidates typically bring a decade or more in professional baseball, combining some playing career with years on minor league or big league staffs.

A typical ladder runs from pitching in college or the minor leagues, to coaching pitchers at a minor league affiliate, to a big league assistant pitching coach or bullpen coach job, and then to the lead chair. Some coaches add a coordinator role along the way, overseeing pitching across several affiliates and writing the development plans that prospects carry from level to level.

The Twins' October 2026 hire shows the profile in practice. Brian Reith, 48, had spent the previous five seasons as pitching coach for the Rays' Triple-A Durham club, where he worked closely with Tampa Bay pitching coach Kyle Snyder. Twins general manager Jeremy Zoll said Reith "brings a wealth of knowledge and experience from both his playing career and his time as a coach." Reith described his approach in practical terms: "we're going to utilize all the technology we can to get the delivery right so we can execute those pitches."

The skills that matter:

Mechanics. A working model of the delivery, from the leg lift through release and finish, and an eye for how fatigue shows up in arm slot, stride and posture.

Data fluency. The ability to read a pitch-tracking report (velocity, spin rate, spin axis, vertical and horizontal movement, release height and extension) without needing an analyst to translate each line, and to know what a high-speed video clip shows that a spreadsheet cannot.

Communication. Turning a finding into one cue a pitcher can repeat under pressure, and adapting for pitchers who learn by feel versus those who want the numbers.

Judgment. Recommending a pitching change in the time between two hitters, with the manager waiting for an answer.

Collaboration. Working daily with analysts, athletic trainers, strength coaches, catchers and the front office without turning disagreements into turf fights.

For someone building toward the job, the practical steps are coaching pitchers at the college or minor league level, learning tracking hardware such as TrackMan, Rapsodo and Edgertronic high-speed cameras firsthand, keeping a record of pitchers who improved and why, and earning the trust of people who later become managers and front office executives.

This is a small, personal market. Each major league staff has one lead pitching coach, and an opening appears when a club decides its run prevention needs a new voice or when a new manager rebuilds the staff. BLS does not project MLB coaching jobs separately, so the useful evidence is the hiring itself.

The fall of 2026 showed how quickly a seat can turn over. On Sept. 28, the Twins announced that pitching coach Pete Maki and assistant pitching coach Luis Ramirez would not return for 2027. Maki had been the pitching coach since July of 2022, and both men were among the few coaches retained when Derek Shelton replaced Rocco Baldelli as manager after the 2025 season, MLB.com reported. Surviving one managerial change did not secure the job: after a season in which Minnesota allowed the sixth-most runs in baseball, the club named Reith its new pitching coach on Oct. 14. The rest of the major league staff, including bench coach Mark Hallberg, hitting coach Keith Beauregard and bullpen coach LaTroy Hawkins, was set to return.

Cincinnati's opening came a different way. Derek Johnson was informed that he would not be retained following a personal leave of absence from June through the rest of the season, and assistant pitching coach Matt Tracy filled in while he was away. Tracy and bullpen coach Oscar Marin both interviewed for the vacancy and were expected to remain in their current roles after the Reds made their hire. Johnson's duties had also included the title of the organization's director of pitching, and MLB.com noted the club still had to decide how to structure the pitching side of its system. For candidates, that detail matters: the big league job can carry organization-wide responsibility, and a coaching change is when a club can redraw it.

The health side of the job is under league scrutiny. MLB's Report on Pitcher Injuries, released in December 2024, suggested that professional baseball consider rule changes that would "increase the value of pitcher health and durability, and decrease the value of short-duration, max-effort pitching." It also called for more research on offseason training and early-season workloads, non-game training activities, biomechanics and pitching styles, and measuring pitcher fatigue. Those are the levers a pitching coach works every week, and a candidate should be ready to explain in an interview how he balances them against the push for velocity.

Pay is opaque. Clubs do not publish what pitching coaches earn, BLS does not report the job separately, and the band on this page is context from a broad industry row rather than a market rate. Job security depends on the manager and the front office, as the Twins' decision shows, and a coach let go by one club can resurface as a lead or assistant on another staff.

For someone aiming at the chair, the realistic plan is to build results at Triple-A or as a big league assistant, document pitchers who improved under your work, stay current on the tracking tools clubs use, and be ready when an executive who knows that work has an opening to fill.

Dear [Club Name] Baseball Operations and Field Staff,

I am applying for the major league pitching coach position. For the past three seasons I have been the assistant pitching coach on a big league staff, and before that I spent five years coaching pitchers at the Double-A and Triple-A levels after a minor league pitching career that ended in Triple-A.

As an assistant, I ran our between-start bullpen program. Each session paired high-speed video with tracking data, and I kept every pitcher's plan to one or two cues so the adjustment would hold up in a game. When a starter's slider lost depth late in the summer, our analyst flagged the change in the data and I traced it to a grip that had crept toward the seam; one bullpen later, the pitch was back. That is how I see the job: the numbers tell me where to look, and the pitcher tells me what he feels.

I also handled reliever availability each afternoon, working with our athletic trainers and bullpen coach so the manager had a clear list before batting practice. I learned to give that list without hedging, and to say no to a pitcher who wanted the ball on a day his body needed rest.

My strongest skill is communication. I coach in English and Spanish, and I adjust to the pitcher in front of me: some want the spin chart, some want one feel cue and a catcher they trust. I would bring that range to your staff, along with a commitment to protecting arms over a long season.

I would welcome the chance to talk about your pitchers and how I would work with your manager, analysts and medical staff.

Sincerely, [Candidate Name]
