The Ottawa Titans Baseball Club joined the now 16 team Frontier League as an expansion franchise in the fall of 2020. The Frontier League of Independent Baseball dates back to the winter of 1992, where several businessmen gathered with aspirations of bringing independent baseball to the West Virginia, eastern Kentucky and southeast Ohio areas. Nearly 30 years later, the Frontier League has grown north of the border as the Canadian–American League of Professional Baseball merged with the Frontier League in October of 2019.

The present-day Frontier League is aligned into two divisions stretched over a 96-game season, with the eight team Can-Am division, consisting of the Titans, Trois-Rivières Aigles (Trois-Rivières, QC), Québec Capitales (Québec City, QC), New York Boulders (Pamona, NY), New Jersey Jackals (Little Falls, NJ), and Sussex County Miners (Augusta, NJ), joined the Frontier League from the Can-Am League. The Washington Wild Things (Washington, PY) were moved to the Can-Am division to balance out the geographic distance in divisions. The Tri-City ValleyCats (Troy, NY) joined prior to the 2021 season after serving as the short season-A affiliate of the Houston Astors for 18 seasons.

The eight team Midwestern division remains intact from the days of pre merge in the Frontier League with the Evansville Otters (Evansville, IN), Florence Y’alls (Florence, KY), Gateway Grizzlies (Sauget, IL), Joilet Slammers (Joilet, IL), Lake Erie Crushers (Avon, OH), Schaumburg Boomers (Schaumburg, IL), Southern Illinois Miners (Marion, IL), and the Windy City Thunderbolts (Crestwood, IL) who round out baseball’s largest independent league, stretching the borders of the Mississippi River to the Atlantic Ocean and from the Ohio River to the Saint Lawrence Seaway.

The Frontier League is also one of independent baseball’s most successful, sending a total 22 and counting players to the major leagues, most recently, Nick Anderson of the Tampa Bay Rays. Not only does the Frontier League send players back into the affiliated ranks, but also coaches, as seven former members of the league were hired into major and minor league coaching roles over the 2019 offseason.
