Who are the Windy City ThunderBolts?
The Windy City ThunderBolts are a professional minor league baseball based out of Crestwood, Illinois and a member of the Frontier League, a MLB Partner League, since 1999.  The ThunderBolts are one of four active league franchises to win multiple titles winning the championship in 2007 & 2008.  We are proud to be the official minor league team of the Chicago Southland.  We were formerly known as the Cook County Cheetahs, but in 2004 we received a new ownership group, name, mascot, and a new look at minor league baseball.  The Cheetah/ThunderBolts franchise has existed since 1995.  The 2022 season will be the organization's 28th overall and in those years the club has gone through three leagues, three stadiums, two names, five playoff appearances, and three championships.  For more information on the history of the club please go to the Team History page on this website.

How long has the Frontier League Existed?
In the winter of 1992-1993, several men got together and decided to start an independent professional baseball league to serve the West Virginia, eastern Kentucky and southeast Ohio areas. They believed they could bring professional baseball to areas that would never have a chance of affiliated professional baseball coming to their communities. The seed was planted and they named their project the Frontier League. These founders approached business people and interested individuals in many different cities about owning and operating the franchises. In late June of 1993, eight cities began play in high school, college and municipal parks. College players quickly heard of the fledgling league and mostly came from the Midwest and East Coast to chase their dreams of playing pro ball.
 
Currently, the Frontier League has sixteen operating organizations throughout Canada and the United States. The league set records for attendance with more than 1.54 million fans visiting the ballparks in 2013. These teams are located in Illinois, Indiana, Kentucky, New Jersey, New York, Ohio, Pennsylvania and three teams in Canada. The Frontier League is now the oldest and biggest MLB Partner League in North America.

What is a MLB Partner League?
While the Frontier League is a part of Major League Baseball minor league structure, it is not specifically affiliated with any MLB team.  Any MLB club can sign Frontier League players and put them into their own system.  All 30 Major League Baseball teams have signed Frontier League players. The Blue Jays, Brewers, Cubs, Dodgers, Giants, Mets, Rangers, and White Sox currently have former ThunderBolts' players or coaches in their organizations. There are 38 players who have reached the Major Leagues after playing in the Frontier League, including the Cook County Cheetah’s Chris Oxspring (with the San Diego Padres in 2005), ThunderBolts' pitchers Dylan Axelrod (White Sox (2011-13) and Reds (14-15)), and Andrew Werner (with the San Diego Padres in 2012).  The Frontier League has over six hundred former players who have been signed into MLB affiliated systems which is the most among MLB Partner Leagues.  The ThunderBolts organization is the team to play for if you want to get noticed as the club has had over 60 player contracts sold to Major League organizations, easily the most in the Frontier League.

Where do the Windy City ThunderBolts play?
The ThunderBolts play at Ozinga Field which is located in Crestwood, Illinois.  Ozinga Field is easily accessible from anywhere in Chicagoland, two blocks east of Cicero Avenue off the Midlothian Turnpike, just 1.5 miles south of I-294.  The facility is unique for its intimacy, while still holding championship sized crowds.  Catered picnic areas and skybox suites are available for rental and are great for group outings. There are three concession stands with a wide menu as well as a grill and beer garden. Ozinga Field also features one of the few upper decks in minor league baseball.

Who are the players?
The Frontier League is the premier developmental professional league in the country.  Only four players on the roster may have turned 28 or older by October 1st of the year in which they wish to play. All other rostered players can not have turned 28 by October 1st of the year in which they wish to play.  Over 65% of the players in the Frontier League enter with previous professional experience, with the remaining having recently completed four years of college baseball.  They are paid to play and come from all over the country and even outside the United States.  At this level, the players always play hard and have a strong passion for the game.
 
How long is the season?
The ThunderBolts regular season consists of 51 home games and 45 road games (a total of 96), running from May 12th to September 4th.  The Playoffs start on September 6th in which the top three teams in each division participate.
