The Baysox captured its first Eastern League Championship in 2015 with a 3–2 series victory over the Reading Fightin Phils. Its 79–63 regular season finish earned the ballclub its second-ever division title by five games over Altoona. The 3–1 Divisional Series win over the Curve sent Bowie to its first championship series in six attempts. One of the team's stars was Trey Mancini, who hit .359 for the season but fell 29 plate appearances short of the 384 needed to qualify for the league batting title due to his having been promoted to the team in June.
