The Pioneer League was established in 1939 as a Class Cminor league consisting of six teams from Idaho and Utah. It later expanded to Montana as part of a failed effort in the 1950s to become a third major league rivalling the American and National leagues, complicated by competition with the Pacific Coast League. By the time it was reclassified as a Rookie league in 1964, only four teams in Idaho remained. Gradually, it returned to Montana and Utah, and expanded into Colorado and the Canadian province of Alberta by 1974, and since then has consistently had eight or more teams competing. In 2021, the league became independent, and ceased all MLB team affiliations, reorganizing as an MLB Partner League representing the Western United States market. An expansion into California followed in 2024.
As of the 2024 season, four teams from Montana, three from Colorado, two from California and Idaho each, and one from Utah compete in the Pioneer League. Nineteen franchises have competed in the league across its 86-year history, with the Missoula PaddleHeads, a current team that joined as the Pocatello Cardinals in the inaugural season, being the longest-tenured. The Ogden Raptors are the current champions, while the Billings Mustangs, also a current team, have won the most championships (15).
In 1948, the league expanded by adding two teams in Montana; the Billings Mustangs and Great Falls Electrics. In these early years, teams in the league either operated independently or were affiliated with Major League Baseball (MLB) or Pacific Coast League (PCL) parent clubs, as the PCL was attempting to grow into a third major league (a bid that ultimately failed). When MLB's Los Angeles Dodgers displaced the PCL's Hollywood Stars in 1958, the Stars relocated and became the "new" Salt Lake City Bees, remaining in the PCL and taking away the Pioneer League's largest market.
In 2016, total league attendance was 616,686,[1] down slightly from the 2015 total of 633,622.[2]
In its final years as an MLB-affiliated league, the Pioneer League was one of two "Rookie Advanced" minor leagues along with the Appalachian League. As such, it occupied the second-lowest rung in the minor league ladder.
Although classified as a Rookie league, the level of play was slightly higher than that of the two "complex" Rookie leagues, the Gulf Coast League and Arizona League. Unlike the complex leagues, Pioneer League teams charged admission and sold concessions. It was almost exclusively the first fully professional league in which many players competed; most of the players had just been signed out of high school. It was a short-season league that competed from late June (when Major League teams signed players whom they selected in the amateur draft) to early September.
As the start of the 2020 season was postponed due to the COVID-19 pandemic before being cancelled on June 30,[4][5] making the 2019 season the league's last as an MLB-affiliated league of Minor League Baseball.
In conjunction with the reorganization of Minor League Baseball in 2021, the Pioneer League was converted to an independent baseball league and was granted status as an MLB Partner League.[6] The reconfigured league continued with the same franchises using the same identities, with the exception of the Orem Owlz who relocated to Windsor, Colorado, as the Northern Colorado Owlz.[6][7] The Boise Hawks also joined the Pioneer League in 2021 after moving from the Northwest League.[8]
The Pioneer League announced a five-year naming rights deal between the league and ticket vendor TicketSmarter that would have the league go as The Pioneer Baseball League presented by TicketSmarter starting in time for the 2022 season.[9]
On April 10, 2024, Kelsie Whitmore signed with the Oakland Ballers of the Pioneer League.[10] She became the first woman to play for that league later that year. On June 6, 2024, she became the first female player to start a Pioneer League game. In that game she struck out one batter.[11]
Organization
Mike Shapiro is the current president of the Pioneer Baseball League, having been a senior executive in a wide range of professional sports including baseball, golf, basketball and hockey.[12]
Jim McCurdy is the commissioner[12] and a past president of the Pioneer Baseball League. McCurdy received his BBA from the University of Houston in 1970 and his JD from the University of Texas School of Law in 1974. He mediated the restructure of Minor League Baseball's governing structure in 1992 and was an inaugural member of the MiLB board of trustees from 1992 to 1994. In 1993, he was appointed by the president of MiLB to serve on the Professional Baseball Executive Council. McCurdy was elevated to the position of league president in 1994, replacing Ralph Nelles who was the president from 1975 to 1993. McCurdy also teaches sports law courses at Gonzaga University School of Law and the University of San Diego School of Law. His publications include: Sports Law: Cases & Materials (with Ray Yasser, C. Peter Goplerud, and Maureen Weston) (7th ed. LexisNexis 2011),[13]Thunder on the Road from Seattle to Oklahoma City: Going from NOPA to ZOPA in the NBA, in Legal Issues in American Basketball ch. IV (Lewis Kurlantzick ed., Academica Press 2011),[13] and, The Fundamental Nature of Professional Sports Leagues, Constituent Clubs, & Mutual Duties to Protect Market Opportunities: Organized Baseball Case Study, in Legal Issues in Professional Baseball ch. IV (Lewis Kurlantzick ed., Academica Press 2005).[13]
League champions have been determined by different means since the Pioneer League's formation in 1939. There were postseason playoffs when the league operated as Class C (1939–1962), except for 1939 and 1956, and for the three years during World War II when the league did not operate. In the league's one year as Class A (1963), there were also postseason playoffs. After becoming a Rookie league in 1964, the league champions were simply the regular season pennant winners through 1977. Since 1978, postseason playoffs have again been held to determine a league champion.[15][16]
