Lena Blackburne Baseball Rubbing Mud is a brand of specially prepared mud used to prepare balls in the sport of baseball before they are put into play. Newly manufactured baseballs have a somewhat slick and glossy surface, so when new they are rubbed down with the mud to reduce the slickness and give pitchers a firmer grip and better control without damaging or discoloring the ball. [1]
Before the discovery of the rubbing mud, baseballs were rubbed in a mixture of water and infield soil, but this method usually discolored the ball's leather surface. [1] Other alternatives at the time were tobacco juice, shoe polish, and soil from under stadium bleachers. They successfully took off the sheen from baseballs, but at the same time, they also damaged and scratched the ball's leather. [2] While Lena Blackburne was a third-base coach for the Philadelphia Athletics (now based in Oakland, California), an umpire complained to him about the method used at the time, prompting Blackburne in 1938 to set out in search of better mud to use to rub against baseballs. Later that decade, Blackburne discovered a suitable rubbing mud (in a location said to be "near" Palmyra, New Jersey) and founded the company that he used to sell it – Lena Blackburne Baseball Rubbing Mud. [3] According to the company, the entire American League used the mud soon after its discovery, and by the 1950s, it was in use by every Major League Baseball (MLB) team, along with some minor league and college teams. [1]
When advancing age prevented him from harvesting the mud, Blackburne, who died in 1968, left the company to a friend, John Haas; [4] according to the company, Haas had accompanied Blackburne during his searches for an appropriate mud. Haas later left the company to his son-in-law Burns Bintliff, who selected one of his nine children, current owner Jim, to carry on the business. [4] Jim Bintliff told CNN in 2009 that the company brought in only about $20,000 per year; at the time, he worked full-time as a printing press operator. [4]
The mud originates from the New Jersey side of the Delaware River. It is cleaned and screened before sale. [1] Each year Jim Bintliff visits the mud's source, returns with 1,000 pounds (454 kg) of it to store over the winter, and sells it the following baseball season. [3] Bintliff told CNN:
If anybody happens to catch me in the act of harvesting mud, I come up with a story to give them a reason I'm putting mud in a bucket. I've told people I use it in my garden, I use it for my rose bushes, I use it for bee stings and poison ivy and any kind of story. [4]
Before all MLB and MiLB games, an umpire or clubhouse attendant rubs six dozen or more balls with the mud to give them a rougher surface, to make them easier for pitchers to grip, and to comply with MLB Rule 4.01(c), which states that all baseballs shall be "properly rubbed so that the gloss is removed." The rubbing mud's unique feature is that it is "very fine, like thick chocolate pudding", [1] and it has been considered the "perfect baseball-rubbing mud". [1] A study in 2024 found that the mud contains an ideal mixture of clay and water, coating the ball with an adhesive residue, while the suspended sand grains enhance friction and therefore the pitcher's grip.

In baseball, the strike zone is the area of space through which a pitch must pass in order to be called a strike even if the batter does not swing. The strike zone is defined as the volume of space above home plate and between the batter's knees and the midpoint of their torso. Whether a pitch passes through the zone is decided by an umpire, who is generally positioned behind the catcher.
A knuckleball or knuckler is a baseball pitch thrown to minimize the spin of the ball in flight, causing an erratic, unpredictable motion. The air flow over a seam of the ball causes the ball to change from laminar to turbulent flow. This change adds a deflecting force to the baseball, making it difficult for batters to hit but also difficult for pitchers to control and catchers to catch; umpires are challenged as well, as the ball's irregular motion through the air makes it harder to call balls and strikes. A pitcher who throws knuckleballs is known as a knuckleballer.
An eephus pitch in baseball is a very high-arcing off-speed pitch. The delivery from the pitcher has very low velocity and often catches the hitter off-guard. The eephus pitch is thrown overhand like most pitches, but is characterized by an unusual, high-arcing trajectory. The corresponding slow velocity bears more resemblance to a slow-pitch softball delivery than to a traditional baseball pitch. It is considered a trick pitch because, in comparison to normal baseball pitches, which run from 70 to 100 miles per hour, an eephus pitch appears to move in slow motion at 55 mph (89 km/h) or less, sometimes as low as 35 mph (56 km/h).
A spitball is a now-illegal baseball pitch in which the ball has been altered by the application of a foreign substance such as saliva or petroleum jelly. This technique alters the wind resistance and weight on one side of the ball, causing it to move in an atypical manner. It may also cause the ball to "slip" out of the pitcher's fingers without the usual spin that accompanies a pitch. In this sense, a spitball can be thought of as a fastball with knuckleball action. Alternative names for the spitball are spitter, mud ball, shine ball, supersinker, or vaseline ball. A spitball technically differs from an emery ball, in which the surface of the ball is cut or abraded. Saliva or Vaseline smooths the baseball, while the emery paper roughens it. The general term for altering the ball in any way is doctoring.
Catcher is a position in baseball and softball. When a batter takes their turn to hit, the catcher crouches behind home plate, in front of the (home) umpire, and receives the ball from the pitcher. In addition to this primary duty, the catcher is also called upon to master many other skills in order to field the position well. The role of the catcher is similar to that of the wicket-keeper in cricket.
The fastball is the most common type of pitch thrown by pitchers in baseball and softball. Its distinctive feature is its high speed. "Power pitchers," such as former major leaguers Nolan Ryan and Roger Clemens, relied on the speed, often exceeding 100mph, and movement of their fastballs to prevent the ball from being hit. As an alternative to the fastball, pitchers can put more movement on slower thrown balls, or throw them towards the inside or outside of home plate where batters cannot easily reach it.
A changeup is a type of pitch in baseball and fastpitch softball.
Earl Sidney Weaver was an American professional baseball manager, author, and television broadcaster. After playing in minor league baseball, he retired without playing in Major League Baseball (MLB). He became a minor league manager, and then managed in MLB for 17 years with the Baltimore Orioles, winning a World Series championship in 1970. Weaver's style of managing was summed up in the quote: "pitching, defense, and the three-run homer." He did not believe in placing emphasis on "small ball" tactics such as stolen bases, hit and run plays, or sacrifice bunts. He was inducted into the Baseball Hall of Fame in 1996.
In baseball, a foul ball is a batted ball that:
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 baseball is the ball used in the sport of baseball. It consists of a rubber or cork center wrapped in yarn and covered with white natural horsehide or cowhide, or a synthetic composite leather. A regulation baseball is 9 to 9.25 inches in circumference i.e. 2.86 to 2.94 inches in diameter, with a weight of 5 to 5.25 ounces.
In baseball, a pitcher may commit illegal motions or actions that constitute a balk. Most of these violations involve pitchers pretending to pitch when they have no intention of doing so. In games played under the Official Baseball Rules that govern professional play in the United States and Canada, a balk results in a dead ball or delayed dead ball. In certain other circumstances, a balk may be wholly or partially disregarded. In the United States, under the National Federation of State High School Associations, a balk results in an immediate dead ball. In the event a balk is enforced, the pitch is generally nullified, each runner is awarded one base, and the batter (generally) remains at bat with the previous count. The balk rule in Major League Baseball was introduced in 1898.
Russell Aubrey "Lena" Blackburne was an American baseball infielder, manager, coach, and scout in Major League Baseball (MLB). He is best known for the creation of his baseball rubbing mud, used to remove the finish on new baseballs and give better grip and control to the pitcher.
Edwin William Hickox is an American retired Major League Baseball umpire. He worked in the American League from 1990 to 1999 and in Major League Baseball from 2005 until his retirement in 2023. Hickox wore uniform number 39 with the American League and number 15 with Major League Baseball. He officiated the Division Series in 2007, 2010, 2012, and 2019 and 2020, as well as the 2011 Major League Baseball All-Star Game.
In a Major League Baseball game played on June 2, 2010, at Detroit's Comerica Park, Detroit Tigers pitcher Armando Galarraga nearly became the 21st pitcher in Major League Baseball history to throw a perfect game. Facing the Cleveland Indians, Galarraga retired the first 26 batters he faced. His bid for a perfect game was ruined one out short when first-base umpire Jim Joyce incorrectly ruled that Indians batter Jason Donald reached first base safely on a ground ball. Galarraga instead finished with a one-hit shutout in a 3–0 victory. He faced 28 batters and threw 88 pitches, striking out three. The game is sometimes referred to as the "28-out perfect game", the "almost perfect game", the "extra perfect game", the "imperfect game", or simply the "Galarraga game".
The Pine Tar Incident was a controversial incident in 1983 during an American League baseball game played between the Kansas City Royals and New York Yankees at Yankee Stadium in New York City on Sunday, July 24, 1983.
An emery ball is an illegal pitch in baseball, in which the ball has been altered by scuffing it with a rough surface, such as an emery board or sandpaper. This technique alters the spin of the ball, causing it to move in an atypical manner, as more spin makes the ball rise, while less spin makes the ball drop. The general term for altering the ball in any way is doctoring. The emery ball differs from the spitball, in which the ball is doctored by applying saliva or Vaseline. Vaseline or saliva smooths the baseball, while the emery paper roughens it.
Baseball personnel have cheated by deliberately violating or circumventing the game's rules to gain an unfair advantage against an opponent. Examples of cheating include doctoring the ball, doctoring bats, electronic sign stealing, and the use of performance-enhancing substances. Other actions, such as fielders attempting to mislead baserunners about the location of the ball, are considered gamesmanship and are not in violation of the rules.
The 2021 pitch doctoring controversy arose in Major League Baseball (MLB) around pitchers' use of foreign substances, such as the resin-based Spider Tack, to improve their grip on the baseball and the spin rate on their pitches. On June 15, 2021, MLB announced a new policy whereby any player caught using foreign substances on baseballs would receive a 10-game suspension. The policy also included umpire inspections of all pitchers during games starting on June 21, a decision that was met with mixed reactions from players and coaches.
