Following the
Portland Beavers' exit after the 2010 season when a
new ballpark was not built, minor league baseball’s
Northwest League approached the city of Hillsboro about relocating a team to the city. Once the Beavers left, the Portland market was the most populous in the country without a professional baseball team.
Milwaukie on the eastern side of the
Portland metropolitan area also had plans to build a stadium for a minor league team. To pay for the construction, the city would sell bonds and repay the money using revenue from the facility, including leasing the field to the minor league team. the Yakima Bears became the leading candidate, as the team previously failed to land a new stadium at
Clark College in the
Vancouver, Washington, area. By April 2012, the Hillsboro City Council approved issuing a request for proposals to design and build a stadium, and hired a sports attorney to assist in the process. The new 4,500-seat stadium, to be built on field four at the complex, is planned to have covered seating, a new orientation to face east, a
beer garden, an entry plaza with artwork, and more
concession stands. Repayment of the bonds would come from revenue generated by the stadium, and if necessary, discretionary funds from the general budget. City officials expected a $7.1 million economic impact annually from the stadium, and said the overall cost of the project would be half of what would normally be expected due to the existing infrastructure at the complex. However, the city council did not consider the matter at that meeting as planned, as negotiations were still continuing with the Yakima Bears and the league. Two weeks later, the Council announced they would again look at approving a
term sheet with the owners of the Yakima franchise, and that the league had two teams interested in possibly relocating to Hillsboro. The deal with the Bears called for a 20-year lease on a $13.4 million stadium, with the team paying rent of $150,000 per year. The rent would increase 3% each year, with the team retaining concession revenues and the city keeping parking revenues, among other provisions. On June 5, the city council approved the offer sheet with Short Season, LLC in a unanimous vote, and agreed to hire Hoffman and SRG to design and build the facility. The deal was contingent upon Short Season signing-off on the deal, plus approval of the league, as well as both Minor and Major League Baseball. The city also acknowledged that revenues may not be enough to cover the debt payment, and that the city may need to use funds paid by
Intel Corporation to the city as part of that company’s tax breaks or other city funds to cover any shortfall. Both the Bears and the Northwest League approved the offer sheet on June 8, and the city signed an agreement with the team on June 26. Final approval of the move was needed by September 4, 2012, from the league,
Minor League Baseball, and
Major League Baseball (MLB), with construction scheduled to start in October 2012. MLB gave the final approval in August 2012 for the relocation, clearing the way for construction to begin. A ground-breaking ceremony with local leaders and team ownership was held on September 21, 2012. In February 2013, the main piece of public art was revealed to be a sculpture entitled
Barometer to be created by Devin Laurence Field. Construction ended in mid-June 2013 with a public opening on June 13. The final construction costs totaled $15.55 million. The Hops' first home game was on June 17, 2013, with a sellout crowd of 4,710 in attendance. The stadium was named project of the year for 2013 by the American Public Works Association for public projects in Oregon between $5 and $25 million. On May 13, 2014, the Ron Tonkin Family of Dealerships signed a ten-year naming rights deal with the city at $150,000 per year, giving the ballpark its new name of Ron Tonkin Field. Tonkin Field hosted the Northwest League's
all-star game in 2017. It was announced in March 2023 that the Hillsboro Hops would build a new ballpark for the 2025 season instead of renovating Ron Tonkin Field. The new ballpark opened for the 2026 season to replace Ron Tonkin Field. ==Features==
