Eastwood Field opened for the 1999 season, when the Erie SeaWolves franchise was relocated to Niles upon the granting of an expansion Eastern League franchise to Erie. With an official seating capacity of 6,000, the park was originally known as Cafaro Field, named for William M. Cafaro, founder of the real estate developer Cafaro Company. The name was changed to Eastwood Field in 2003 to match the Eastwood Mall, a Cafaro property on U.S. Route 422, behind which the ballpark was built. On August 14, 2012, the stadium hosted the 2012 New York-Penn All Star Game.[6] In 2015, the Fall Experimental Football League announced the Boston Brawlers franchise would relocate and play its home games at Eastwood Field as the Mahoning Valley Brawlers, however, the team would cease operations prior to its first game.[7]
The stadium's highest attendance was recorded on July 18, 2024, when 7,869 fans were in attendance for 717 Credit UnionFinancial Wellness Night, where the Mahoning Valley Scrappers beat the State College Spikes 16-8. Free tickets to attend the game were provided by the credit union on a first-come first-served basis.[8]
