Roy E. Lee Field is named for former coach Roy Lee, the founder of the SIUE baseball program. Lee amassed 237 wins in 11 seasons as the Cougars' head coach. He enjoyed nine winning seasons, and finished his career with a .617 winning percentage. Lee put the Cougars into the national spotlight with eight consecutive appearances in the NCAA Championships from 1970 to 1977. In three appearances at the Division II College World Series, the Cougars' best finish was second place in 1976.

SIUE baseball began playing at the current site with the start of the 1972 season.

Major renovations took place in 2004 and again in 2005. The site was transformed from a field to a stadium in 2005, when the grandstand was upgraded to include the brick stadium, permanent restrooms, concession stands, concourse, and entrance gate.

Another round of renovations took place following the 2010 season when the Cougars received a new clubhouse and home dugout. The natural grass infield was replaced with Astro Turf® GameDay Grass in time to play all but three home games on it during the 2011 season. The Astro Turf® surface means less rainouts, but more importantly more practice time on the field during the offseason. During the summer of 2014 the natural grass outfield also was replaced with Astro Turf® GameDay Grass, and the outfield wall was replaced, making a truly symmetrical outfield.

Prior to the 2023 season, the infield surface was replaced again, this time with a FieldTurf DoublePlay surface.

Renovation to the Simmons Baseball Complex were made possible due to a donation by John Simmons and the Simmons Law Firm.
