The Royal Oak Leprechauns are a summer collegiate baseball team in the Northwoods League. They are based in Royal Oak, Michigan, and play their home games at Memorial Park.[4]

History

Founded in 2015, the team began playing in the Great Lakes Summer Collegiate League (GLSCL) in 2016 as the Irish Hills Leprechauns, based in Adrian, Michigan.[5][6] They remained in Adrian through the 2018 season and went on hiatus during the 2019 season.[7]

In 2020, MLB All-Star and Gold Glove winning infielder D.J. LeMahieu began supporting the Leprechauns as a primary donor, funding numerous renovations to Memorial Park in Royal Oak.[8][9] The relocated Leprechauns resumed play in the GLSCL in 2021, changing their name to the Royal Oak Leprechauns.[10] LeMahieu later transitioned to the role of team President[11] and eventually Field Manager.[12]

In October 2023, it was announced that the Leprechauns would be leaving the GLSCL and joining the Northwoods League (NWL), another summer collegiate league, for the 2024 season.[13][14][15]

In 2026, the Leprechauns had a standout season in the NWL. Managed by D.J. LeMahieu, they finished the regular season with a 43-27 record and clinched a playoff berth with the best second half record in the Great Lakes East division. In the sub-division championship series, they swept the Kenosha Kingfish before defeating the Madison Mallards for the Great Lakes division championship.[16] They faced the St. Cloud Rox in a winner-take-all NWL championship game on 8/13/26. Both teams were held scoreless through six innings, with Jack Sequin on the mound for the Leps. The Rox scored one run in the 7th, and the Leprechauns got on the board in the 8th with a 2-RBI single by Luke Kosko.[17] The Leprechauns defeated the Rox by a score of 3-1.[18]

2026 was also a successful individual season for several Leprechaun players. Three Leps (Luke Kosko, Oliver Service, Kellen English) were selected to represent the Great Lakes Division in the NWL All-Star game, held at Field of Dreams Ballpark in Dyersville, Iowa.[19] Upon completion of the regular season, outfielder Luke Kosko led all NWL players in both home runs (17) and RBI (72). Pitcher Spencer Boynton led all NWL pitchers in total strikeouts with 76.[20] Kosko was named 2026 Northwoods League Most Valuable Player. Additionally, infielder Mason Barth, Boynton, and Kosko were all named to the NWL full-season All-Star team which was announced after the season.[21]
