The transformation of Linfield's baseball facility began in the late 1980s. Most of the improvements were the result of direct support from community members, who donated untold amounts of time, energy and resources.

Roy Helser Field, together with Jim Wright Stadium, has developed from a below-average facility to a jewel among Northwest small colleges.

The most recent project, completed in 2008, involved covering the infield with a FieldTurf artificial playing surface. Drainage was improved and construction of covered, enclosed batting cages on the venue site was undertaken.

In 2000, outdoor lighting was added to the field. Musco lighting systems were installed in the fall of 2000 to give more flexibility in scheduling while enhancing the facilities and allowing for NCAA post-season competition. Outdoor lighting also provides more quality opportunities for the McMinnville-area youth teams during the summer.

Wright Stadium was added to Helser Field in 1990, replacing portable aluminum bleachers and a chainlink backstop.

The stadium, a crescent-shaped brick and concretegrandstand, offers intimate, unobstructed views of the action on the field. It contains 860 aluminum-backed seats, along with a fully enclosed press box, public address system, dressing room and
covered storage areas.

While the stadium was being built, Helser Field was undergoing renovation as well. Automatic underground sprinklers were put in place, Astroturf was installed in the batting cages, dugouts were erected and new grass was planted. A cyclone fence with vinyl slats was built along the field's perimeter, which was pushed back 20 feet to allow to allow room for the new stadium.

On May 25, 1991, Linfield dedicated its newly completed baseball stadium at Roy Helser Field in honor of Jim Wright, his wife, Sondra, and parents Edith (Hall) Wright of McMinnville and the late Neale Wright, class of 1929. Jim Wright, a Portland businessman, provided a large portion of the funding
for the new stadium.

The first baseball field, cornered by Linfield Avenue and Davis Street, was home of the Wildcats for over four decades. In 1971, the Wildcats moved to their present location, south of Maxwell Field, near the end of Lever Street. The field wasformally dedicated in 1973 in recognition of former athletic director, baseball and basketball coach Roy Helser. When Helser's 1966 baseball team won the NAIA championship, it was the college's first national championship in any sport.
