The Rising Importance of Pitch Tipping in Major League Baseball

In recent years, pitch tipping has emerged as a significant concern in Major League Baseball (MLB), particularly highlighted during the 2025 postseason. Teams are increasingly investing time and resources to detect and prevent pitch tipping, which can provide opponents with a competitive edge. This trend culminated in a new MLB rule for the 2026 season, mandating that base coaches remain within their designated boxes to limit their ability to observe pitchers closely.

Pitch tipping, where pitchers inadvertently reveal the type of pitch they are about to throw, has been a part of baseball for decades. A notable instance occurred during the 2015 postseason when the Kansas City Royals capitalized on a pitcher's glove position to score runs. Over the years, the practice has evolved, with teams now employing advanced technology and analytics to identify tipping patterns.

Several MLB executives and managers have weighed in on the significance of pitch tipping. Giants General Manager Zack Minasian noted that while pitch tipping is not illegal, it is not policed as rigorously as in the past. Rockies Manager Warren Schaeffer shared a specific example of how a pitcher's foot positioning could be exploited by opponents. Diamondbacks GM Mike Hazen emphasized the importance of monitoring and addressing pitch tipping within their own pitching staff.

The implications of pitch tipping are profound, as even minor advantages can significantly influence game outcomes. As noted by Angels GM Perry Minasian, teams may have knowledge of an opponent's pitches but still struggle to score runs, underscoring the complexity of hitting in baseball. The focus on pitch tipping reflects a broader trend in MLB where teams are increasingly reliant on data and analytics to gain any possible edge.

The enforcement of the new rule requiring base coaches to stay in their boxes is a direct response to the growing concerns about pitch tipping. This regulation aims to level the playing field and reduce the potential for teams to gain unfair advantages through observation.

While many in the league acknowledge the importance of pitch tipping, there are concerns about its implications for fair play. Some executives argue that the current environment fosters paranoia, with teams overly focused on perceived advantages rather than the actual performance of their players.

There is a divergence of opinion regarding the effectiveness of pitch tipping. Some players, like White Sox pitcher Sean Newcomb, have shared personal anecdotes about how their habits could inadvertently signal pitches. However, others, like Rockies Manager Schaeffer, express frustration over the inability to control such tipping, indicating a gap in understanding how widespread and impactful the issue truly is.

• “The deal was this: If you see the light reflecting off the glove, it's his breaking ball. If you don't see any light, it's his fastball. Because it's how he turned his glove at the right angle.” — J.J. Picollo, General Manager, Kansas City Royals

• “We have a review process independent of outcome. Oftentimes they think they were tipping and we go look and it's like, 'No, you were throwing it down the middle.' It's a big part of modern-day baseball. It's as much about prevention than finding out the other team's tips.” — Unnamed MLB Executive

• “All it takes is for one team to have a tip on one reliever in one inning and that's the game.” — Warren Schaeffer, Manager, Colorado Rockies
