Colorado Rockies

The Colorado Rockies are a professional Major League Baseball (MLB) franchise based in Denver, Colorado. The team competes in the National League (NL) West division since their inaugural season in 1993. The Rockies arrived in Denver in 1993 and are the only professional baseball team in the Rocky Mountain West. The team plays its home games at Coors Field, located in the Lower Downtown area of Denver. The Rockies were MLB's first team based in the Mountain Time Zone. Over the course of their history, the franchise has been defined by a legendary hitter-friendly ballpark, a handful of storied players, and one remarkable run to the World Series in 2007.

Founding and Early History

Denver had long been a hotbed of minor league baseball as far back as the late 19th century, with the original Denver Bears (or Grizzlies) competing in the Western League. The Rocky Mountain News first reported the score of a game in 1862, and by 1900 the Denver Bears became the state's first prominent professional team. By 1955, the Bears were thriving as a farm franchise for the powerful New York Yankees. The team changed its name to the Denver Zephyrs in 1984 and remained in the city until 1992.

Those big-league dreams came true in June 1991, when Major League Baseball awarded new franchises to Denver and Miami. Denver officials quickly realized they would need a new stadium to help attract a franchise, but the city had neither the funds for the project nor a sufficient amount from private donors. Colorado Governor Roy Romer quickly put together a new ownership group, and in August 1990, voters from the six metro Denver counties approved a one-half of 1 percent sales tax to fund the stadium. In 1991, as part of Major League Baseball's two-team expansion along with the Florida (now Miami) Marlins, an ownership group representing Denver led by John Antonucci and Michael I. Monus was granted a franchise. They took the name "Rockies" due to Denver's proximity to the Rocky Mountains, which is reflected in their logo; the name was previously used by the city's first NHL team, now the New Jersey Devils.

Because the Rockies' new ballpark — Coors Field — would not be finished until 1995, the team played its first two seasons in Mile High Stadium, then the home of the NFL's Denver Broncos. Their vision became reality when Denver was awarded a franchise in 1991, and their arguments were vindicated two years later when the Rockies played their first game in front of more than 80,000 fans, the largest opening day crowd in baseball history. The Rockies won that game against Montreal 11–4, the franchise's first major league win. That year the Rockies set the all-time Major League record for attendance, drawing 4,483,350 fans — still the MLB record.

Coors Field

Coors Field opened for baseball on April 26, 1995. The Colorado Rockies had joined the National League two years earlier, playing their first two seasons in Mile High Stadium while Coors was being built. It cost $215 million, and the Coors Brewing Company contributed another $30 million for naming rights. Located at Twentieth and Blake Streets, Coors Field was part of the transformation of Lower Downtown (LoDo) from the city's Skid Row into a district of sports bars, bistros, and sundry nightlife. It was also the first baseball-only park in the National League since Dodger Stadium was built in 1962.

Coors Field is Major League Baseball's highest-altitude ball field, a fact that can change the game depending on whether you are in the batter's box or on the pitcher's mound. At nearly a mile high, the row of purple seats in the upper deck of the stadium is exactly 5,280 feet above sea level. In its first decade, the above-average number of home runs earned Coors Field a reputation as the most hitter-friendly park in Major League Baseball, earning the critical nicknames "Coors Canaveral" and "Williamsport." Colorado's light, dry air often turns would-be fly balls into home runs. To account for this, the outfield fences were placed farther from home plate than usual, creating one of the largest outfields in major league baseball.

To combat the effects of altitude and dry air on game balls, the franchise introduced a landmark solution. The idea came from Rockies employee Tony Cowell, who had observed that his leather boots dried faster at high altitude and figured that baseballs would do the same. Cowell figured that the baseballs would not travel as far if they were slightly moist, and thought that if the baseballs were kept in a humidor, they would lose some of their bounce. Since 2002, the balls have been kept at 70 degrees and 50% humidity in a 9-by-9-foot, 7-foot-high chamber that looks like a walk-in cooler. The humidor quickly made a difference: home-run production fell from 268 in 2001, the most in the major leagues, to 185 in 2007, ranking 10th. The Elias Sports Bureau also found that runs scored per game were down as well, from 13.4 in 2001 to 10.6 in 2007. Coors Field has hosted the 1998 MLB All-Star Game and the 2021 MLB All-Star Game.

On-Field History and Postseason Appearances

Since 1995, the Rockies have played at Coors Field, which earned a reputation as a hitter's park, as demonstrated by the 1995 team that had four players — Dante Bichette, Vinny Castilla, Andrés Galarraga, and Larry Walker — each hit 30 home runs; they were nicknamed the "Blake Street Bombers." Colorado made a surprise run to a postseason appearance in just its third year of existence, earning the NL Wild Card in 1995, which was followed by a first-round playoff loss to the Atlanta Braves. The Rockies posted a respectable 83–79 record in each of the next two seasons, but they failed to build any lasting success in the aftermath of the franchise's impressive first few years. Colorado struggled through the start of the 21st century, finishing no better than second to last in its division from 1998 to 2006.

The franchise's most memorable chapter came in 2007. Having a record of 76–72 at the start of play on September 16, the Rockies proceeded to win 14 of their final 15 regular season games. The stretch culminated with a 9–8, 13-inning victory over the San Diego Padres in a one-game playoff for the wild card berth. Colorado then swept their first seven playoff games to win the NL pennant. In 2007, a reconfigured Rockies team led by outfielder Matt Holliday, first baseman Todd Helton, and All-Star relief pitcher Brian Fuentes went on a remarkable late-season run; their hot streak extended to the playoffs, where the Rockies swept both the Philadelphia Phillies and the Arizona Diamondbacks en route to their first NL pennant. Stellar pitching from the Boston Red Sox stymied the hot-hitting Rockies in the World Series, and the team was swept off baseball's biggest stage almost as quickly as it arrived.

The Rockies made another postseason appearance in 2009, suffering a four-game loss to the Phillies in the opening round of the playoffs, but the team returned to producing predominantly losing seasons by the early 2010s. That changed in 2017 when the Rockies, led by star third baseman Nolan Arenado, added 12 wins to their previous season's total to qualify for a spot in the NL Wild Card Game. Colorado qualified for the postseason for two consecutive seasons for the first time in 2018, advancing to the divisional series, where the Rockies were swept by the Milwaukee Brewers. Overall, the Rockies have qualified for the postseason five times, each time as a Wild Card winner. The Rockies have never won a division title, but they advanced to the 2007 World Series after gaining a playoff berth as the NL Wild Card entrant.

Notable Players and Franchise Legends

The franchise has seen legendary players, including Todd Helton and Larry Walker, both of whom have left significant marks on the team's history and performance.

Larry Walker played for the Rockies from 1995 to 2004 and remains one of the most decorated players in franchise history. The right fielder was a four-time All-Star, a five-time Gold Glove Award winner, and a three-time batting champion with Colorado. He also won the 1997 National League MVP Award, the only MVP honor in club history. Walker ranks first in franchise history in batting average (.334), on-base percentage (.426), and slugging percentage (.618), and hit 258 homers with the Rockies in addition to 848 RBIs and 126 stolen bases. Walker became the first player in franchise history to be elected to the Hall of Fame in 2020.

Todd Helton spent his entire career with Colorado and is the all-time franchise leader in most offensive categories. The first baseman spent his entire 17-year big league career with the Rockies, setting franchise records of 1,401 runs, 369 homers, and 1,406 RBI. Helton enjoyed arguably his best season in 2000, leading the major leagues in batting average (.372), RBI (147), doubles (59), total bases (405), extra base hits (103), slugging percentage (.698), and OPS (1.162), while also leading the NL in hits (216) and on-base percentage (.463). On January 23, 2024, Helton was elected to the Hall of Fame, receiving 79.7% of the vote. The all-time franchise leader in most offensive categories, Helton played his entire career with the Rockies from 1997 to 2013 and was elected to the National Baseball Hall of Fame in 2024 — the first Rockie to be so honored.

Shortstop Troy Tulowitzki played in Colorado from 2006 to 2015, making five All-Star appearances during that time. His teammate, outfielder Carlos Gonzalez, was a Rockie from 2009 to 2018. Gonzalez is third in franchise history with 1,330 hits and tied for fourth in home runs with 227. In 2018, Colorado's Trevor Story became the first shortstop in major league history to record 40 doubles, 30 homers, and 25 stolen bases in a season, ultimately earning his first Silver Slugger for his offensive efforts.

Both Walker and Helton have their numbers retired at Coors Field. Colorado retired Helton's number 17 on August 17, 2014. Fresh off his MLB Hall of Fame induction, Larry Walker had his No. 33 retired by the team before a game against the San Francisco Giants in September 2021. The Rockies will also unveil statues of both Hall of Famers at Coors Field in 2026.

Recent Seasons

In 2023 and 2024, the Colorado Rockies lost over 100 games each season — 103 games in 2023 and 101 in 2024. Their record of 8–42 (.160 winning percentage) during the 2025 season marked the worst 50-game start of any team in Major League Baseball history, two games worse than the 2023 Oakland Athletics' 10–40 start. At the end of 2025, the Rockies hold an all-time record of 2,364–2,818, a .456 winning percentage that is the worst among active MLB franchises. After the Denver Nuggets won the 2023 NBA Finals, the Rockies became the only one of Denver's franchises in the major North American professional sports leagues yet to win a championship.

Despite these recent struggles, the team continues to develop young talent. The Rockies' spring training home, Salt River Fields at Talking Stick in Scottsdale, Arizona, opened in March 2011 and is shared with the Arizona Diamondbacks. The organization looks to prospects such as outfielder Charlie Condon as part of a longer-term rebuilding effort while honoring its legacy through the upcoming Coors Field statues of Walker and Helton in 2026.
