Offensive Baseball Predated Coors Field

While Coors Field became synonymous with offensive fireworks, it is important to note that the era of high-scoring games began well before the ballpark's inception in 1995. American League teams consistently boasted higher batting averages and accumulated more hits than the Rockies, even after Coors Field's establishment. In fact, during Mark McGwire's historic 1998 season, when he hit a remarkable 70 home runs, only one of them was achieved in Denver. Coors Field was merely a contributor to baseball's shift toward a hitter's game, rather than the catalyst itself.

The Influence of Altitude on Baseball

Coors Field's unique location at an elevation of 5,280 feet above sea level has a significant impact on the game. Due to the thinner air, the baseball travels approximately 9 percent farther than it does at sea level. For instance, a home run hit 400 feet in Yankee Stadium at sea level would travel around 408 feet in Atlanta but reach an impressive 440 feet in the Mile High City.

It is worth noting, however, that altitude alone is not solely responsible for the increase in home runs. The wind plays a crucial role as well, sometimes overshadowing the impact of altitude. A 10-mph tailwind can transform a 400-foot shot into a 430-foot blast, demonstrating the significant influence wind can have on turning fly balls into home runs. Combining a favorable tailwind with the high altitude can create optimal conditions for power hitters.

Altitude's Effect on Pitching

The influence of altitude extends beyond hitting; it also affects pitching. Thinner air reduces air resistance, allowing fastballs to gain an extra six inches of movement and making curveballs slightly less sharp. Pitchers must adapt their strategies to the unique conditions at Coors Field, accounting for the altered physics of their pitches.

Mile High Memories

Coors Field's history is not limited to its time since 1995. Before the construction of the ballpark, the Colorado Rockies played at Mile High Stadium for a brief but memorable two-year stint. In just 135 dates at Mile High, the Rockies attracted an impressive 7,701,861 fans, averaging 57,051 per game. The inaugural season in 1993 drew 4,483,350 spectators, and if not for the early end to the 1994 season, the Rockies were on track to surpass that figure, averaging 58,598 fans per game. The team experienced extraordinary attendance numbers, with 52 games exceeding 60,000 attendees and 21 games surpassing the 70,000 mark.


Coors Field's reputation as an offensive powerhouse is well-deserved, with the 1999 season serving as a testament to its unique qualities. However, it is crucial to recognize that offensive baseball existed prior to the establishment of Coors Field. Factors such as wind and thinner air play crucial roles in the game's outcome, influencing home runs and pitching alike. Coors Field remains an unforgettable part of baseball history, captivating fans with its thrilling displays of power and creating lasting memories for all who have experienced it.
