The following list is of the top 100 pitchers in career strikeouts in Major League Baseball. In baseball, a strikeout occurs when the batter receives three strikes during his time at bat. Strikeouts are associated with dominance on the part of the pitcher and failure on the part of the batter.
Nolan Ryan [1] [2] [3] has the most career strikeouts in Major League Baseball. During a record 27-year career, he struck out 5,714 batters. The American League record is held by Roger Clemens [4] (4,167 strikeouts), [5] while in the National League, the record is 4,000 by Steve Carlton. [6] [7]
The parentheses adjacent to an active player denote the number of strikeouts in the current season. The last change in the cutoff for the top 100 occurred on June 22, 2024, when Charlie Morton struck out his 1,957th batter, displacing Whitey Ford.

A player is considered "inactive" if he has not played baseball for one year or has announced his retirement.
In baseball, an at bat (AB) or time at bat is a batter's turn batting against a pitcher. An at bat is different from a plate appearance. A batter is credited with a plate appearance regardless of what happens during their turn at bat, but a batter is charged with an at bat only if that plate appearance does not have one of the results enumerated below. While at bats are used to calculate certain statistics, including batting average and slugging percentage, a player can qualify for the season-ending rankings in these categories only if they accumulate 502 plate appearances during the season.
A base on balls (BB), better known as a walk, occurs in baseball when a batter receives four pitches during a plate appearance that the umpire calls balls, and is in turn awarded first base without the possibility of being called out. The base on balls is defined in Section 2.00 of baseball's Official Rules, and further detail is given in 6.08(a). Despite being known as a "walk", it is considered a faux pas for a professional player to actually walk to first base; the batter-runner and any advancing runners normally jog on such a play.
Lynn Nolan Ryan Jr., nicknamed "the Ryan Express", is an American former professional baseball pitcher and sports executive. Over a record 27-year playing career in Major League Baseball (MLB), Ryan pitched for the New York Mets, California Angels, Houston Astros, and Texas Rangers. After his retirement in 1993, Ryan served as chief executive officer (CEO) of the Texas Rangers and an executive advisor to the Houston Astros. He was inducted into the Baseball Hall of Fame in 1999 in his first year of eligibility, and is widely considered to be one of the greatest pitchers of all time.
In baseball or softball, a strikeout occurs when a batter accumulates three strikes during a time at bat. It means the batter is out, unless the third strike is not caught by the catcher and the batter reaches first base safely as a result. A strikeout is a statistic recorded for both pitchers and batters, and is usually denoted by the letter K, or sometimes by the initialism SO. A "strikeout looking"—in which the batter does not swing and the third strike is called by the umpire—may be denoted by an inverted K.
Steven Norman Carlton is an American former professional baseball player. He played in Major League Baseball as a left-handed pitcher for six different teams from 1965 to 1988, most notably as a member of the Philadelphia Phillies with whom he won four Cy Young Awards as well as the 1980 World Series. He was elected to the Baseball Hall of Fame in 1994 in his first year of eligibility.
In baseball and softball, a win–loss record is a statistic that indicates the number of wins and losses credited to a pitcher. For example, a 20–10 win–loss record would represent 20 wins and 10 losses.
Randall David Johnson, nicknamed "the Big Unit", is an American former professional baseball pitcher who played 22 seasons in Major League Baseball (1988–2009) for six teams, primarily the Seattle Mariners and Arizona Diamondbacks.
In baseball statistics, Batters Faced (BF), also known as Total Batters Faced (TBF) or Batters Facing Pitcher (BFP) is the number of batters who made a plate appearance before the pitcher in a game or in a season.
In Major League Baseball (MLB), the 3,000 strikeout club is the group of 19 pitchers who have struck out 3,000 or more batters in their careers. Walter Johnson became the first member in 1923, and was the only one until Bob Gibson joined in 1974. The most recent addition is Max Scherzer, who joined on September 12, 2021. The group includes three left-handed pitchers: CC Sabathia, Steve Carlton, and Randy Johnson. Randy Johnson reached the mark with the fewest games pitched and innings pitched. The Minnesota Twins were the first of four franchises to see multiple pitchers record their 3,000th strikeout: Walter Johnson in 1923 and Bert Blyleven in 1986. The other teams with multiple members are the Chicago Cubs, the New York Yankees, and the Houston Astros. César Gerónimo is the only player struck out by two pitchers for their 3,000th strikeout: Gibson in 1974 and Ryan in 1980. Ten 3,000-strikeout pitchers are also members of the 300-win club. Seven members were named to the All-Century Team, a list of MLB's best 100 players; fans later elected four of them as starters. Thirteen members of the club also won a Cy Young Award in their careers.
Edward Augustine Walsh was an American pitcher and manager in Major League Baseball, nicknamed "Big Ed". From 1906 to 1912, he had several seasons where he was one of the best pitchers in baseball. Walsh holds the record for lowest career earned run average, 1.82. He is one of two modern (post-1901) pitchers to win 40 or more games in a single season, and the last pitcher to do so. He is the last pitcher from any team to throw more than 400 innings in a single season, a feat he accomplished in 1907 and 1908. Though injuries shortened his career, he was inducted into the Baseball Hall of Fame in 1946.
Terry Lane Felton is a former pitcher for the Minnesota Twins.

In baseball statistics, total bases is the number of bases a player gains with hits. It is a weighted sum with values of 1 for a single, 2 for a double, 3 for a triple and 4 for a home run. For example, three singles is three total bases, while a double and a home run is six total bases.
