The Windy City ThunderBolts are a professional baseball team based in the Chicago suburb of Crestwood, Illinois, in the United States. The ThunderBolts are a member of the West Division of the Frontier League, which is not affiliated with Major League Baseball. From the 1999 season to the present, the ThunderBolts have played their home games at Standard Bank Stadium.
The team was previously named the Cook County Cheetahs prior to the 2004 season. An ownership change instigated the name change.
On August 26, 2007, the ThunderBolts won their first Central Division title. On September 17, 2007, they defeated the Washington Wild Things to win the Frontier League championship, three games to two. In 2008, they repeated a Divison Title as the West Division Champions and Frontier League champions, defeating the Kalamazoo Kings three games to none in the championship series. (NOTE: After heavy rains flooded Homer Stryker Field the entire 2008 Championship game was played at the Thunderbolts Standard Bank Stadium.) They thus became only the second Frontier League team to win back-to-back titles, joining the 2001-02 Richmond Roosters.
