The Art Of Pitching



Pitching is a complex and delicate craft. Mastering the perfect throw is what separates the good from the great in baseball. A pitcher’s skill set is not just about speed or power. It’s about control, technique, and strategy.

Basics Of Legal Pitching Techniques

Legal pitching plays by the rules. Each pitch brings together form and function. Here’s a breakdown of legitimate techniques:

  • Windup – starting motion for a pitch
  • Set Position – standing still before throwing
  • Grip – how fingers hold the ball
  • Delivery – motion of throwing the ball
  • Follow-Through – body movement after releasing the ball

Upholding these elements is crucial. Each contributes to pitch precision and speed. Young pitchers learn these fundamentals early on.

How Illegal Pitches Deviate From The Norm

Illegal pitches break the set guidelines. They offer an unfair advantage. Examples include:

Illegal PitchWhat Makes It Illegal
BalkMisleading motion without throwing
SpitballUsing saliva on the ball
ScuffballDamaging the ball’s surface

An illegal pitch can lead to batters gaining an edge. Umpires watch for these moves. Penalties apply if caught. Pitchers sometimes still take the risk.


The Spitball Scandal

A pitch once dominated America’s favorite pastime, sparking intrigue and scandal. Known as the spitball, it wasn’t just any old throw; it was the underhand trick of the trade for pitchers looking to confound batters. Delve into the sordid history of this controversial tactic, from its mysterious origins to its eventual banishment from the game.

Origin And Usage

Picture this: it’s the early 1900s, and baseball is in its gritty glory days. Pitchers search for an edge, a way to make the ball behave unpredictably. Enter the spitball. Players promised a dazzling show with every slick throw, leaving batters baffled and fans thrilled. But what started as a secret weapon soon became the game’s worst-kept secret.

The spitball involved using saliva, sweat, or other substances to wet one side of the ball. This imbalance caused it to dip, dart, and dance through the air, challenging even the sharpest hitters. It wasn’t long before pitchers boasted of an arsenal of “trick” pitches, each more inventively doctored than the last. Soon, every team had a spitball specialist.

Banning The Spitball

As the roaring twenties rolled in, the spitball faced a striking out. The climax came in 1920 when Ray Chapman, a beloved shortstop, suffered a fatal blow from a spitball pitch. The game needed change. The following year, baseball officials drew a line: no more spitballs.

Still, a few seasoned spitballers were grandfathered in. These pitchers could use the pitch until they retired. But for upcoming players? The spitball was off-limits, a relic of baseball’s wilder days. Strict new rules were enforced, and official inspectors kept a keen eye on the ball. Baseball had cleaned up its act, but the legend of the spitball scandal echoes through history.

  • 1920: Spitball banned in Major League Baseball.
  • Existing spitball pitchers granted exemption until retirement.
  • New pitches and strategies developed as baseball evolved.

Cut from the game, the spitball became a tale of caution and nostalgia. This marked the start of a new era, where skill trumped secret tactics. Baseball had turned a page, but the spitball remains its most slippery scandal.

Doctoring The Ball

In the high-stakes world of professional baseball, some players resort to underhanded tactics to gain an edge. One such method is doctoring the ball, a prohibited practice to alter a baseball’s condition for advantage. This crafty tactic tampering with the ball can affect its flight, making it more challenging for the batter to hit.

Methods Of Altering The Ball

Players have devised creative ways to doctor the ball:

  • Scuffing: Using rough surfaces to create irregularities on the ball’s surface.
  • Applying Substances: Adding sticky or slick substances like pine tar or Vaseline.
  • Spitballs: Using saliva or sweat to change the ball’s weight distribution.

These methods aim to disrupt the ball’s aerodynamics. They can make pitches move in unpredictable ways.

Detecting Tampered Balls In Play

Umpires and players stay vigilant to keep the game fair. They look for signs of tampering:

  1. Unusual Movement: Balls that move oddly signal tampering.
  2. Pitcher’s behavior: Suspicious actions on the mound may trigger inspections.
  3. Ball Inspection: Close examination of the ball’s surface.

Maintaining integrity in baseball is crucial. It comes from fair competition and respect for the rules.
