2023 Frontier League season

The 2023 Frontier League season was the 30th season of operation (29th season of play) of the Frontier League (FL). The regular season began on May 11, 2023, when the Florence Y'alls were hosting the Gateway Grizzlies at Thomas More Stadium.

The playoffs concluded on September 17, with the Québec Capitales defeating the Evansville Otters in the finals in five games, winning their second consecutive championship and 9th in franchise history.

Team and rule changes
The 16 teams in the league are split evenly between two divisions, East and West. The Empire State Greys return as a traveling team with a roster of players from the Empire Professional Baseball League.

The season will be played with a 96-game schedule; teams play either three or four series against their divisional rivals while facing the eight teams from the other division at least one series each. The top three teams in each division will qualify for the 2023 playoffs, with the first-place team already qualifying for the division championship, and the second and third place teams playing each other in a wild card game.

The league's player compensation budget increased by $230,000 compared to 2022. Teams were required to spend a maximum of $365,000 on their 24-player rosters with a minimum of $13,800 per player. Veterans could earn up to $22,800, and each team's highest-paid player could make as much as $27,300. For players aged 23 and younger, only 50% of their salary counts towards the cap.
