The Mendoza Line is baseball jargon for a .200 batting average, the supposed threshold for offensive futility at the Major League level. [1] It derives from light-hitting shortstop Mario Mendoza, who failed to reach .200 five times in his nine big league seasons. [2] When a position player's batting average falls below .200, the player is said to be "below the Mendoza Line".
Mendoza was a lightly used shortstop from Chihuahua, Mexico, who played for three franchises during a nine-season Major League career. While his fielding was highly regarded, his hitting was not. His batting average was between .180 and .199 in five seasons out of nine.
When he had trouble staying above .200 in 1979, teammates began to chide him. "...Tom Paciorek and Bruce Bochte used it to make fun of me," Mendoza said in 2010. "Then they were giving George Brett a hard time because he had a slow start that year, so they told him, 'Hey, man, you're going to sink down below the Mendoza Line if you're not careful.' And then Brett mentioned it to Chris Berman from ESPN, and eventually it spread and became a part of the game."
Berman deflects credit back to Brett in popularizing the term. "Mario Mendoza — it's all George Brett," Berman said. "We used it all the time in those 1980s SportsCenters . It was just a humorous way to describe how someone was hitting." [3]
Mendoza ended up finishing 1979 below his own "line", at .198. His hitting improved modestly in 1980 and 1981, enough that even with another sub-.200 in his final season of 1982 he raised his career batting average to .215. [4]
The term is also used outside of baseball to convey a similar connotation of unacceptably subpar performance:

Shortstop, abbreviated SS, is the baseball or softball fielding position between second and third base, which is considered to be among the most demanding defensive positions. Historically, the position was assigned to defensive specialists who were typically poor at batting and were often placed at the bottom of the batting order. Today, shortstops are often able to hit well and many are placed at the top of the lineup. In the numbering system used by scorers to record defensive plays, the shortstop is assigned the number 6.

He batted .346 in the 1925 World Series to help the Pirates take their first championship in 16 years.

In baseball, the batting order or batting lineup is the sequence in which the members of the offense take their turns in batting against the pitcher. The batting order is the main component of a team's offensive strategy. In Major League Baseball, the batting order is set by the manager, who before the game begins must present the home plate umpire with two copies of his team's lineup card, a card on which a team's starting batting order is recorded. The home plate umpire keeps one copy of the lineup card of each team, and gives the second copy to the opposing manager. Once the home plate umpire gives the lineup cards to the opposing managers, the batting lineup is final and a manager can make changes only under the Official Baseball Rules governing substitutions. If a team bats out of order, it is a violation of baseball's rules and subject to penalty.

The 1921 Detroit Tigers finished in sixth place in the American League, 27 games behind the Yankees, with a record of 71–82. Despite their sixth-place finish, the 1921 Tigers amassed 1,724 hits and a team batting average of .316—the highest team hit total and batting average in American League history. Detroit outfielders Harry Heilmann and Ty Cobb finished No. 1 and No. 2 in the American League batting race with batting averages of .394 and .389, and all three Detroit outfielders ranked among the league leaders in batting average and RBIs. As early proof of the baseball adage that "Good Pitching Beats Good Hitting", the downfall of the 1921 Tigers was the absence of good pitching. The team ERA was 4.40, they allowed nine or more runs 28 times, and only one pitcher had an ERA below 4.24.
Mark Duane Wagner is a former Major League Baseball infielder. He played nine years in Major League Baseball for the Detroit Tigers (1976–1980), Texas Rangers (1981–1983), and Oakland Athletics (1984).
In baseball, batting average (BA) is determined by dividing a player's hits by their total at-bats. It is usually rounded to three decimal places and read without the decimal: A player with a batting average of .300 is "batting three hundred". If necessary to break ties, batting averages could be taken beyond the .001 measurement. In this context, .001 is considered a "point", such that a .235 batter is five points higher than a .230 batter.
