Some pro lacrosse as well as professional and amateur softball has also been played at Wintrust Field due to the late start (mid-May) of the independent baseball season.

Now called Wintrust Field, the Alexian Brothers Medical Center in nearby Elk Grove purchased the naming rights to the ballpark in 2000.

At that point, the village and park district which owned the stadium began eviction proceedings against the Flyers for failure to pay $551,800 in back rent.

On February 24, 2011, a Cook County court ruled the Flyers could be evicted, ordered the now defunct team to pay the back rent, and the naming rights contract was terminated when there was no professional baseball played in the park in 2011.

The franchise is known as the Schaumburg Boomers named after the "booming dance" of the male Greater Prairie Chicken and the team earned a 54–42 record during its Inaugural Season, falling one win short of a playoff berth.
