In baseball (hardball or softball), a starting pitcher or starter is the first pitcher in the game for each team. A pitcher is credited with a game started if they throw the first pitch to the opponent's first batter of a game. Starting pitchers are expected to pitch for a significant portion of the game, although their ability to do this depends on many factors, including effectiveness, stamina, health, and strategy.
A starting pitcher in professional baseball usually rests three, four, or five days after pitching a game before pitching in another. Therefore, most professional baseball teams have four, five or six starting pitchers on their rosters. These pitchers, and the sequence in which they pitch, is known as the rotation. A team's best starter is known as the ace, and is almost always the first man to pitch in the rotation. In modern baseball, a five-man rotation is most common.[1]
In contrast, a pitcher who enters the game after the first pitch of the game is a relief pitcher. Occasionally, an opening pitcher is used for only a few innings, and is replaced by a long reliever or a pitcher who would typically be a starting pitcher.
Workload
Under ideal circumstances, a manager of a baseball team would prefer a starting pitcher to pitch as many innings as possible in a game. Most regular starting pitchers pitch for at least five innings on a regular basis, and if a pitcher is unable to do so, there is a high probability that he will, in the future, be relegated to duty in the bullpen. In modern baseball, a starting pitcher is rarely expected to pitch for more than seven or eight innings, at which point, responsibility for the game is passed to relief pitchers, including specialist pitchers such as setup pitchers and closers.
Often, a starting pitcher is subject to a pitch count, meaning the manager will remove him from the game once he has thrown a specific number of pitches. The most common pitch count for a modern pitcher is about 100, and it is now rare for a starting pitcher to throw more than 125 pitches in a game. Pitch count limits are especially common for starting pitchers who are recovering from injury.
At the youth level, such as in Little League Baseball, pitch counts are usually capped at a certain point as well as required rest before a pitcher can pitch again.[2]
In the 2018 MLB season, the Tampa Bay Rays debuted a variant of the starting pitcher dubbed the "opener,"[3] whose role is a hybrid between those of the traditional starting pitcher and the closer. In the opener strategy, a relief pitcher starts the game and pitches the first one or two innings (when guaranteed to face the top hitters in the opponent's lineup) before giving way to a long reliever to work the middle innings of the game. Due to their lighter workload and conditioning, openers are able to pitch more frequently than a traditional starter.
In the early decades of baseball, it was not uncommon for a starting pitcher to pitch 300 innings or more, over the course of a season. In addition, there are accounts of starting pitchers pitching on consecutive days, or even in both games of a doubleheader. It is believed that these feats were only possible because pitchers in the early years of the game, unlike modern starters, rarely threw the ball with maximum effort.
A starting pitcher who can be counted on to consistently throw many innings is known as a workhorse. An example of a modern-day workhorse pitcher was Roy Halladay, who was the active leader in both complete games thrown and shutouts before his retirement in 2013.[4]
A pitcher that normally isn't a regular member of a team's starting rotation that situationally starts a game is commonly referred to as a "spot starter."[citation needed] Pitchers that make spot starts are often relief pitchers mainly long-relief pitchers out of the bullpen that are tasked to pitch multiple innings or a starting pitcher that is promoted from a club's minor league team to make sporadic starts. Spot starts typically occur because of emergency instances like a sudden injury to a scheduled starting pitcher in the rotation, or if there are multiple doubleheaders requiring a tight workload.[5][6]
Statistics
A starting pitcher must complete five innings of work in order to qualify for a "win" in a game he starts. Under NCAA baseball rules, which govern intercollegiate baseball, a starting pitcher who pitches fewer than five innings can still earn a win if he pitches for a certain amount of time that is determined before the start of the game. It is possible to be credited with a loss despite pitching fewer than five innings. A starter who works six or more innings while giving up three or fewer earned runs is said to have achieved a "quality start". A starter who finishes the game without having to be relieved by the bullpen is said to have thrown a "complete game". The pitcher who throws a complete game is almost always in a position for a win.
Pitch selection
Starting pitchers usually have a variety of pitches to choose from, broken into a number of categories.
Fastballs: A pitch thrown hard (anywhere from the upper 80s to over 100mph) and which generally follows a mostly straight trajectory. There are a number of different types of fastballs. The four-seam fastball is the hardest thrown pitch, but also has very little movement or break to it. The two-seam fastball is slightly slower than the four-seam fastball (generally in the mid 80s to low 90s), but breaks slightly inward to the pitcher's throwing arm as well as dropping slightly (i.e., a left-handed pitcher throwing a two-seam fastball will have it tail slightly right-to-left). The movement and velocity of the sinker is similar to that of the two-seamer, though sinkers tend to break earlier than two-seamers. The cut fastball (cutter) is similar to the two-seam fastball in velocity, but breaks to the opposite side of a pitcher's throwing arm (i.e., a right-handed pitcher will have it break right-to-left).
Hard breaking balls: The most prominent of the hard breaking balls is the slider. A slider is a pitch that breaks sharply in the direction of the pitcher's arm travel (left to right for a left-handed pitcher). It travels slower than a fastball (usually in the 80s), but faster than the slower breaking balls. The other hard breaking ball, the split-finger fastball (splitter), mimics the fastball. The splitter breaks late in its flight path and downwards from the point of release, with a little bit of tailing action. The split-finger is usually thrown in the low to upper 80s, although some travel upwards of 90mph.
Soft breaking balls: The most common soft breaking ball is the eponymous curveball. The curve breaks in the direction of the pitcher's arm travel from the point of release on through the entire arc of its flight. If one were to look at a clock, a straight drop curveball would be 12–6. A right hander with slightly more lateral break will have a curveball breaking in a 1–7 manner or with more lateral movement in a 2–8 manner. A left hander that throws a curveball with more lateral break will either have an 11–5 or 10–4 curveball. Curveballs travel from the low 60s to mid 80s in speed. The other soft breaking ball is the screwball, which is essentially a reverse curveball, as it breaks in the opposite direction of the pitcher's arm travel. The screwball is a fairly rare pitch in modern baseball, due in part to a widespread belief that it causes damage to the arm. However, a 2014 New York Times investigation concluded that this belief is unfounded, and that the screwball causes no more injury than any other pitch.[7]
Other off-speed pitches: Two other major off-speed pitches are used by pitchers today, one far more so than others. The changeup, which has variants such as the circle changeup, the vulcan changeup or the palmball, is a slow pitch that is thrown with the same arm motion and arm velocity of a fastball, but with a much different grip that keeps the ball from achieving the same speed; usually the changeup is 10–20mph slower than the pitcher's fastballs. This visual distortion from a fast arm swing and a slower pitch is used to disrupt the hitter's timing. The other major off-speed pitch is the knuckleball. The knuckleball is a very difficult pitch to master, both for the pitcher (due to its unique grip and delivery manner) and for his catcher (due to the pitch being thoroughly unpredictable in its travel).

In baseball, the pitcher is the player who throws ("pitches") the baseball from the pitcher's mound toward the catcher to begin each play, with the goal of retiring a batter, who attempts to either make contact with the pitched ball or draw a walk. In the numbering system used to record defensive plays, the pitcher is assigned the number 1. The pitcher is often considered the most important player on the defensive side of the game, and as such is situated at the right end of the defensive spectrum. There are many different types of pitchers, such as the starting pitcher, relief pitcher, middle reliever, lefty specialist, setup man, and the closer.
Mark Allan Hendrickson is an American former baseball and basketball player. Hendrickson was a pitcher in Major League Baseball (MLB) and played power forward in the National Basketball Association (NBA) and Continental Basketball Association (CBA). He is one of just 13 athletes to play in both MLB and the NBA. He is a former pitching coach for the Aberdeen IronBirds.
The fastball is the most common type of pitch thrown by pitchers in baseball and softball. "Power pitchers," such as former American major leaguers Nolan Ryan and Roger Clemens, rely on speed to prevent the ball from being hit and have thrown fastballs at speeds of 95–105 miles per hour (153–169 km/h) (officially) and up to 108.1 miles per hour (174.0 km/h) (unofficially). Pitchers who throw more slowly can put movement on the ball, or throw it on the outside of home plate where batters can't easily reach it.
In baseball, a slider is a breaking ball pitch that tails laterally and down through the batter's hitting zone. It is thrown at a speed that is lower than a fastball, but higher than the pitcher's curveball.
In baseball and softball, the curveball is a type of pitch thrown with a characteristic grip and hand movement that imparts forward spin to the ball, causing it to dive as it approaches the plate. Varieties of curveball include the 12–6 curveball, power curveball, and the knuckle curve. Its close relatives are the slider and the slurve. The "curve" of the ball varies from pitcher to pitcher.
A changeup is a type of pitch in baseball and fastpitch softball.
In baseball, the pitch is the act of throwing the baseball toward home plate to start a play. The term comes from the Knickerbocker Rules. Originally, the ball had to be thrown underhand, much like "pitching in horseshoes". Overhand pitching was not allowed in baseball until 1884.
In baseball, a circle changeup or circle change is a pitch thrown with a grip that includes a circle formation, hence the name circle changeup. The circle is formed by making a circle with the index finger, holding the thumb at the bottom of the ball parallel to the middle finger and holding the ball far out in the hand. The ball is thrown turning the palm out.
In baseball, an off-speed pitch is a pitch thrown at a slower speed than a fastball. Breaking balls and changeups are the two most common types of off-speed pitches. Very slow pitches which require the batter to provide most of the power on contact through bat speed are known as "junk" and include the knuckleball and the Eephus pitch, a sort of extreme changeup. The specific goals of off-speed pitches may vary, but in general they are used to disrupt the batter's timing, thereby lessening his chances of hitting the ball solidly or at all. Virtually all professional pitchers have at least one off-speed pitch in their repertoire. Despite the fact that most of these pitches break in some way, batters are sometimes able to anticipate them due to hints that the pitcher gives, such as changes in arm angle, arm speed, or placement of fingers.
A gyroball is a type of baseball pitch used primarily by players in Japan. It is thrown with a spiral-like spin, so that there is no Magnus force on the ball as it arrives at home plate. The gyroball is sometimes confused with the shuuto, another pitch used in Japan.
Jered David Weaver is an American former professional baseball starting pitcher. He played in Major League Baseball (MLB) for the Los Angeles Angels and San Diego Padres.

He is the younger brother of former pitcher Jeff Weaver.
Kyuji Fujikawa is a Japanese former professional baseball pitcher. He pitched for the Hanshin Tigers of Nippon Professional Baseball (NPB) and the Chicago Cubs and Texas Rangers of Major League Baseball (MLB).
The shuuto (シュート) or shootball is a baseball pitch. It is commonly thrown by right-handed Japanese pitchers such as Hiroki Kuroda, Noboru Akiyama, Kenjiro Kawasaki, Daisuke Matsuzaka, Yu Darvish and Masumi Kuwata. The most renowned shuuto pitcher in history was Masaji Hiramatsu, whose famous pitch was dubbed the razorshuuto because it seemed to "cut the air" when thrown.
In baseball, sidearm is a motion for throwing a ball along a low, approximately horizontal plane rather than a high, mostly vertical plane (overhand).
