[3] This early Cape League operated through the 1939 season and disbanded in 1940, due in large part to the difficulty of securing ongoing funding during the Great Depression.

[20] Massachusetts Governor Charles F. Hurley was on hand to throw out the ceremonial first pitch to open the 1937 season in Orleans as the team faced Harwich.

[33] Orleans won the league title in its inaugural 1947 campaign, defeating the Upper Cape champion Mashpee Warriors in that year's championship series, which was played as a Labor Day home-and-home doubleheader.

Facing Mashpee's CCBL Hall of Fame ace hurler Donald Hicks in Game 2, Bremner continued his torrid pace, going 4-for-6, but Orleans trailed by two going to the final frame.

In the top of the ninth, Orleans exploded for seven runs, then brought in Bruninghaus to close out the 15–10 win and clinch the club's first Cape League crown.

In Game 1 at Keith Field, Orleans sent Bruninghaus to the mound and gave him ample support, including a three-run homer by Jim Gage in a 13–5 rout.

He went on to no-hit Sagamore for three more innings, while Orleans put the game away with a four-run 11th, capped by Junie Lee's three-run bomb, to take a 10–6 win that completed the repeat championship sweep.

[48] In the teams' fifth consecutive championship series meeting, Orleans bowed to Sagamore in the 1954 title tilt,[49] but Peterson's boys were back to face a new opponent the following season.

After playoff series wins over North Truro AFS and Yarmouth to claim the Lower Cape title, Orleans advanced to the 1955 championship round against the Cotuit Kettleers.

In Game 2 at home, Orleans lefty Ray Tucker tossed a four-hitter as the club scratched out a 4–2 victory to take a commanding series lead.

[51] For the first time since joining the revived league, Orleans failed to reach the CCBL title series in 1956, but the club was right back in championship form the following season.

The Red Sox sent Doug Higgins to the mound in Game 1 and jumped ahead early with four runs in the first and never looked back, routing the Gatemen by a final of 10–1.

Orleans completed the two-game sweep before a home crowd in Game 2, getting a homer and a pair of singles from Stan Wilcox on the way to a 5–3 victory that secured the club's seventh CCBL crown in 11 years.

[53] In 1959, Orleans reached the CCBL title series for a final time during this era, facing old nemesis Sagamore in a matchup of the two dominant clubs of the period.

Carlton was drafted in 1967 by the hometown Boston Red Sox, where he was a perennial all-star throughout the 1970s In 2000, he was inducted into the National Baseball Hall of Fame in Cooperstown, New York.

[65] The 1968 Orleans team featured CCBL Hall of Famer Phil Corddry, who went 9–2 with 108 strikeouts in 92 innings for the Cardinals to win the league's Outstanding Pitcher Award.

[83][84] The 1985 season was highlighted by Cardinal hurler Bob O'Brien's no-hitter against Cotuit in which he came short of a perfect game by just two walks and benefited from outfielder Glenn Fernandez's home run-robbing catch at the fence of a smash by Kettleers' slugger Greg Vaughn.

The team featured slugger Gary Alexander, who hit .313 with 12 home runs, and ace hurlers and future major leaguers Jeff Conine and Mike Ignasiak.

In the 11th, Petkovsek gave up a lead-off single to Alexander, and was left in the game to face Kevin Garner, who popped one just over the right field fence for the series-winning walk-off score.

Todd Haney added the insurance with a two-run blast in the seventh to give Orleans the 3–0 win and title series sweep, with Alexander taking home playoff MVP honors for his brilliant power display.

[28] The team lost in the finals to Wareham,[90] but Thomas went on to a stellar career with the Chicago White Sox and was inducted into the National Baseball Hall of Fame in 2014.

[93] In the championship series, the Cards faced a strong Wareham team, and took Game 1 at Clem Spillane Field by a 2–1 margin on a first-inning two-run homer by Aaron Boone.

Catcher Steve Fishman snuck a two-run homer down the line in the sixth, and the Cards walked away with a 5–1 win to sweep the series and claim the crown, with Ciaccio taking home playoff MVP honors.

The team finished atop the East Division with an impressive 29–13–2 record, and prevailed over Y-D in the playoff semi-finals, but was shut down by Wareham in the title series.

[102] Manager Carmen Carcone brought the Cards back to the title series for a second consecutive season in 2003, the team powered by playoff MVP and CCBL home run derby champion Cesar Nicolas.

[117] The team qualified for the playoffs in nine of ten years in the decade, winning East Division titles in 2011, 2015 and 2017, and reaching the championship series in 2013 before falling to Cotuit.

[120][121][122] Notable players of the decade included CCBL Hall of Famer Kolten Wong, who hit .341 with 22 stolen bases to claim the league MVP Award in 2010.

[123] CCBL Hall of Famer Marcus Stroman played for the Firebirds in 2010 and 2011, allowing zero earned runs over 34 career innings pitched,[124] and Trevor Gott was the league's Outstanding Relief Pitcher for Orleans in 2011.

[128] The 2018 Firebirds featured league Outstanding Pro Prospect J.J. Bleday, a CCBL all-star outfielder who hit .311 with five home runs,[129][130] and hurlers Mitchell Senger and Aaron Ochsenbein, who tossed a combined no-hitter against Brewster.

[136][137][138] The 2023 Firebirds were led by CCBL All-Star Game MVP Jo Oyama,[139] Outstanding Relief Award winner Sean Matson, and 10th Player recipient Derek Clark,[140] and swept through the East Division playoffs before falling to Bourne in the league championship.
