The Sticky Stuff: A Deep Dive into Pine Tar in baseball
Pine tar. The mere mention of the word can send shivers down the spines of baseball purists while eliciting knowing grins from players and fans alike. This sticky, brownish-black substance has a long and storied history in baseball, one filled with controversy, innovation, and a healthy dose of gray areas.
From its humble beginnings as a simple grip enhancer to its modern-day incarnation as a symbol of the constant arms race between hitters and pitchers, pine tar has played a fascinating role in shaping the game we know and love.
What is Pine Tar?

Pine tar is a natural product derived from the wood of pine trees. Through a process of heating and distillation, the wood yields a thick, viscous substance with a distinctive tar-like odor. While its primary use historically has been in shipbuilding and woodworking, it found its way into baseball thanks to its adhesive properties.
The Early Days: Grip and Gain
The use of pine tar in baseball dates back to the early days of the game. Players quickly discovered that a bit of the sticky substance on their bat handles could significantly improve their grip, especially in hot and humid conditions. This was particularly crucial in the pre-batting glove era, when sweaty hands could easily slip off the smooth surface of a wooden bat.
Early uses of pine tar were largely unregulated. Players applied it liberally, often extending beyond the handle and onto the barrel of the bat. While this enhanced grip, it also raised concerns about altering the flight of the ball.

The Rise of Controversy: The “Pine Tar Incident”
The most famous incident involving pine tar occurred on July 24, 1983, during a game between the Kansas City Royals and the New York Yankees. Royals star George Brett, known for his powerful swing, hit a two-run home run in the ninth inning to give his team a 5-4 lead.
However, Yankees manager Billy Martin, suspecting Brett had used an excessive amount of pine tar, challenged the home run. After a lengthy delay, the umpires ruled that Brett had indeed violated the pine tar rule, which at the time limited its application to the first 18 inches of the bat handle.
Brett’s home run was controversially nullified, and the game resumed with the Yankees winning 5-4. The ensuing uproar was immense. Brett, furious and heartbroken, stormed the field in protest. Fans and media alike debated the merits of the rule, the fairness of the umpires’ decision, and the very nature of the game itself.
The “Pine Tar Incident” became a defining moment in baseball history, a watershed event that highlighted the complexities and ambiguities surrounding the use of foreign substances in the game.
The Evolving Rules: A Constant Struggle for Balance
The 1983 incident led to a tightening of the rules regarding pine tar. The league clarified the definition of “handle” and emphasized the importance of umpires strictly enforcing the 18-inch limit. However, the issue of foreign substances in baseball remained a persistent one.
In recent years, concerns have grown about pitchers using sticky substances to enhance their grip on the baseball, leading to increased spin rates and decreased hit rates. These substances, which can include spider tack, sunscreen, and even foreign objects like rosin bags, have become a major point of contention between players, managers, and the league.
Major League Baseball has taken steps to address this issue, implementing stricter enforcement measures and introducing new rules to limit the use of foreign substances. However, the battle continues, with players constantly seeking ways to gain an edge within the ever-shifting boundaries of the rules.
The Ethical Debate: Where to Draw the Line?
The use of pine tar and other foreign substances in baseball raises important ethical questions. Where does the line lie between enhancing performance and gaining an unfair advantage? Is it acceptable for players to use substances that can significantly alter the flight of the ball or the difficulty of hitting?
Some argue that the use of certain substances is simply a part of the game, a form of innovation and adaptation that has always driven baseball forward. Others contend that any substance that artificially enhances performance undermines the integrity of the game and creates an uneven playing field.
The debate over pine tar and other foreign substances is not just about the rules; it’s about the very essence of baseball itself. It’s about the balance between tradition and innovation, between individual skill and technological advantage.
The Future of Pine Tar: A Constant Evolution
The story of pine tar in baseball is far from over. As the game continues to evolve, so too will the rules and regulations surrounding the use of foreign substances.
Technological advancements, such as the use of radar guns to measure spin rates, are likely to play an increasingly important role in monitoring and enforcing these rules.
Ultimately, the goal is to find a balance that allows players to compete fairly while preserving the integrity and spirit of the game. Whether pine tar will continue to play a significant role in this ongoing saga remains to be seen.
Conclusion
From its humble beginnings as a simple grip enhancer to its modern-day incarnation as a symbol of the constant arms race between hitters and pitchers, pine tar has left an indelible mark on the history of baseball.
The “Pine Tar Incident” of 1983 serves as a powerful reminder of the complexities and controversies surrounding the use of foreign substances in the game.
As the game continues to evolve, the debate over pine tar and other sticky substances will undoubtedly continue to shape the future of baseball.
The story of pine tar is a microcosm of the larger struggle to define fair play and preserve the integrity of this beloved American pastime.
