The pitcher is the player who starts every play by throwing the ball toward home plate for the batter to hit. It is one of the most decisive roles in baseball: the pitcher sets the tempo of the game, works closely with the catcher, and directly influences how many runs the other team can score. This guide explains what the pitcher does, the main types of pitches, the specialist roles in a professional bullpen, the rules that govern pitching, and — importantly for young players in Wellington and across New Zealand — how to protect a growing arm.
Key Points
- The pitcher (position #1) starts every play by throwing toward home plate and works with the catcher as the “battery”.
- Throwing strikes consistently is the foundation; walks and wild pitches often hurt a team more than hits.
- Common pitches include the four-seam fastball, two-seam/sinker, cutter, slider, curveball, changeup and splitter.
- Professional roles include the starter, long reliever, middle reliever, setup pitcher and closer.
- Youth arm care is critical — follow Pitch Smart pitch-count and rest limits and never pitch three days in a row.
What the pitcher does on the field
In baseball’s numbering system the pitcher is position number 1, and every defensive play begins with a pitch. The pitcher stands on the pitcher’s mound and delivers the ball toward the catcher, who crouches behind home plate. Together the pitcher and catcher are known as the “battery”, and they decide which pitch to throw and where to place it.
The pitching distance is fixed: the front of the pitching rubber sits 60 feet 6 inches (about 18.44 metres) from the back point of home plate at senior and professional level. Youth leagues use shorter distances that grow with age. The pitcher’s job is to throw the ball through the strike zone — the area over home plate between the batter’s knees and the midpoint of the torso — often enough to record outs, while mixing speeds and locations so the batter cannot settle into a rhythm. If you are still learning the basics of the sport, our overview of how to play baseball puts the pitcher’s role in context, and you can see where every fielder sits in our guide to baseball position numbers.

Throwing strikes comes first
Before any advanced technique, the foundation of pitching is the ability to throw strikes consistently. In youth baseball especially, walks (four balls, which send the batter to first base for free) and wild pitches often hurt a team more than allowing a hit, because they hand out bases without the batter earning them. A pitcher who fills the strike zone forces batters to swing and put the ball in play, where the fielders behind them can make outs.
Practical habits help. Focusing on the catcher’s glove as a single target, keeping the first pitch simple to get ahead in the count, and settling into a steady, repeatable rhythm all improve control. Accuracy is a trainable skill — our guide to improving your throwing accuracy and our baseball pitching mechanics guide break down the movement patterns that make strikes repeatable.
The main types of pitches
Skilled pitchers throw more than one type of pitch so batters cannot predict speed or movement. The common families are:
- Four-seam fastball — the hardest, straightest pitch, used to challenge hitters and reach the top of the strike zone.
- Two-seam fastball / sinker — slightly slower than a four-seam and moves toward the pitcher’s arm side while dropping, encouraging ground balls.
- Cutter — a fastball with a small, late glide away from the pitcher’s arm side.
- Slider — a breaking ball with sharp, glove-side sideways movement, thrown harder than a curveball.
- Curveball — a slower breaking ball with topspin that produces a downward drop.
- Changeup — thrown with fastball arm speed but a grip that reduces velocity, so the batter swings early.
- Splitter — an off-speed pitch with a sharp late drop as it nears the plate.
Coaches usually advise young players to master a fastball and a changeup first, and to delay heavy breaking-ball use until the arm has matured, because the twisting motion adds stress. You can look up any unfamiliar word in our glossary of baseball terms.
Specialist pitching roles in a professional game
At the top level, such as Major League Baseball, pitchers are given distinct roles so a coach can match the right arm to the moment. The typical structure is:
- Starting pitcher — begins the game. A modern starter usually aims for six or seven strong innings; complete nine-inning games are now rare.
- Long reliever — enters early if the starter leaves quickly, and can cover several innings.
- Middle reliever — typically works the fifth, sixth or seventh innings to bridge to the late-game arms.
- Setup pitcher — usually pitches the eighth inning to protect a lead ahead of the closer.
- Closer — a power specialist who finishes the ninth inning of a close game to secure the win.
The relievers who wait for their turn sit together in the bullpen. Understanding how many arms a squad carries helps: see our explainer on how many players are on a baseball team.
Rules that shape modern pitching
A few recent Major League rules have changed how pitchers work and are worth knowing if you watch the professional game:
- The pitch clock — introduced in 2023, it gives the pitcher 15 seconds to start the delivery with the bases empty and 20 seconds with runners on. From the 2024 season the runners-on limit was reduced to 18 seconds. Breaking the clock is an automatic ball.
- The three-batter minimum — since 2020, a pitcher who enters the game must face at least three batters or finish the half-inning before being replaced, which limits mid-inning pitching changes.
Two common statistics measure a pitcher’s effectiveness: ERA and WHIP. We explain each in our guides to what ERA means in baseball and what WHIP means in baseball.
Protecting a young arm
Arm health is the single most important consideration for youth pitchers. Throwing too many pitches, or pitching without enough rest, can cause overuse injuries that last well beyond a single season. USA Baseball’s widely used “Pitch Smart” guidelines set daily pitch-count limits and required rest by age. In summary:
- Ages 7–8: up to 50 pitches per day.
- Ages 9–10: up to 75 pitches per day.
- Ages 11–12: up to 85 pitches per day.
- Ages 13–16: up to 95 pitches per day.
- Ages 17–18: up to 105 pitches per day.
Rest scales with workload: for ages 7–14, throwing 66 or more pitches in a day calls for four days of rest before pitching again, and Pitch Smart advises that no pitcher should take the mound on three consecutive days regardless of counts. Coaches and parents in New Zealand should track pitch counts, watch for fatigue or pain, and prioritise recovery over short-term results. For broader guidance see our baseball safety tips for kids in Wellington.
Mental focus and resilience
Even the best pitchers give up hits and have difficult innings. What separates reliable pitchers is the habit of letting go of the last pitch and concentrating fully on the next one. Staying calm after a mistake, keeping a consistent routine on the mound, and trusting the catcher’s plan all help a pitcher hold their composure under pressure — a skill that develops with match experience as much as with practice.
Getting started as a pitcher in Wellington
You do not need to be a professional to enjoy pitching. Junior and club programmes across the Wellington region give new players a safe, structured way to learn the position, and Baseball New Zealand oversees the pathway from local clubs through to national teams. Beginners can build velocity and control safely at home with our tips on training fast pitching at home before joining organised games. The key is to start with sound mechanics, throw strikes, and treat the arm as a long-term asset.
Legendary pitchers in baseball history
Many pitchers have set benchmarks that define the position. Cy Young, whose name is on the award given each year to the best pitcher in each MLB league, retired in 1911 with a record 511 career wins. Nolan Ryan holds the career strikeout record with 5,714. Modern greats such as Randy Johnson, Roger Clemens, Pedro Martinez, Bob Gibson and Greg Maddux — along with the legendary Satchel Paige — are widely studied for their command, movement and durability. Today, two-way star Shohei Ohtani has renewed global interest in elite pitching; read more in our profile of Shohei Ohtani.

Frequently Asked Questions (FAQ)
How far does a pitcher stand from home plate?
At senior and professional level the front of the pitching rubber is 60 feet 6 inches — about 18.44 metres — from the back point of home plate. Youth leagues use shorter distances that increase as players get older.
What is the difference between a starter and a closer?
A starting pitcher begins the game and aims to pitch several innings, commonly six or seven. A closer is a relief specialist brought in to finish a close game, usually pitching the final inning to protect a narrow lead.
What pitch should a beginner learn first?
Most coaches recommend mastering a fastball and a changeup first. Breaking pitches such as the curveball and slider add extra strain on the arm, so they are usually introduced later, once mechanics and arm strength have developed.
How many pitches can a child safely throw?
Under the widely used Pitch Smart guidelines, daily limits range from about 50 pitches for ages 7–8 up to 105 for ages 17–18, with required rest days that increase with the number of pitches thrown. No young pitcher should pitch on three consecutive days.
What does the pitch clock do?
The pitch clock, used in Major League Baseball since 2023, limits how long a pitcher can take between pitches — 15 seconds with the bases empty and 18 seconds with runners on (reduced from 20 in 2024). Exceeding the limit results in an automatic ball.
