ESL Ballpark (originally known as Frontier Field and later Innovative Field) is a baseball stadium at One Morrie Silver Way in downtown Rochester, New York. It has been the home of the Rochester Red Wings of the International League since 1997. The park opened in 1996, replacing Silver Stadium in northern Rochester, which had been home to professional baseball in Rochester since 1929. Although the stadium was built for baseball, ESL Ballpark has had several tenants in numerous sports, including the Rochester Raging Rhinos of the United Soccer Leagues from 1996 to 2005, and the Rochester Rattlers of Major League Lacrosse from 2001 to 2002. The ballpark seats 10,840 spectators for baseball. Rochester-based telecommunications company Frontier Telephone of Rochester held the naming rights to the ballpark from its opening in 1996 until the 2022 baseball offseason. Originally in December 2015, an agreement was reached to maintain the name for a further ten years. However, on October 24, 2022, a new naming rights agreement was reached with Innovative Solutions, a Henrietta-based information technology firm, as Frontier was looking to cut back on sponsorship costs after its bankruptcy in 2020. The stadium was renamed Innovative Field. On February 10, 2026, Monroe County and the Red Wings announced a new naming rights agreement with ESL Federal Credit Union, which was originally founded in 1920 by George Eastman to serve employees of Eastman Kodak. Ground was broken on the stadium in November 1994. The ballpark, designed by Ellerbe Becket, opened on July 11, 1996. Although it was always intended to be primarily a baseball facility, it was constructed to be able to accommodate the Rochester Rhinos soccer team as well. The Red Wings moved from Silver Stadium to Frontier Field at the conclusion of the 1996 International League season. The first event at the ballpark was a concert by The Beach Boys on July 11, 1996. The facility also hosted the 1996 Drum Corps Associates World C
