77Australian RP Brandan Bidois competing for Pittsburgh Pirates in MLB.
Brandan Bidois was born in Brisbane, Queensland, on 21 June 2001. A right-handed pitcher who bats and throws right-handed, he developed through Australian baseball and represented Australia at junior level before signing with the Pittsburgh Pirates as an international free agent in September 2019. He played for his hometown Brisbane Bandits in the Australian Baseball League during the 2020–21 period, gaining senior experience before moving into the Pirates’ professional development system.
Bidois’ early professional pathway was affected by the cancellation of the 2020 minor-league season during the COVID-19 pandemic. He made his affiliated minor-league debut with the Florida Complex League Pirates in 2021 and missed the 2022 season because of an injury. He returned with the Bradenton Marauders in 2023, progressed to the Greensboro Grasshoppers and Indianapolis Indians in 2024, and moved through Bradenton, Greensboro, Altoona and Indianapolis during 2025.
His breakthrough came in 2025, when he produced an outstanding relief season across Pittsburgh’s minor-league system. The Pirates reported that he posted a 0.74 earned-run average over 61.0 innings, the lowest ERA in Minor League Baseball among relief pitchers with at least 60 innings and the lowest such mark since 2019. He also recorded 18 consecutive scoreless innings during that campaign. Those performances led Pittsburgh to select his contract and add him to the organisation’s 40-man roster in November 2025.
The Pirates promoted Bidois to the major leagues in May 2026. He made his MLB debut on 13 May 2026 against the Colorado Rockies, pitching one relief inning at PNC Park. His debut made him the first Australian-born player to play for the Pittsburgh Pirates. His mother travelled from Brisbane to Pittsburgh for the occasion, and MLB reported that it was the first time he had seen her in two years.
Bidois’ role is that of a bullpen or relief pitcher rather than a starter. The official Pirates profile lists him at 6 feet 2 inches and 174 pounds, with the pronunciation “bid-WAH”. The supplied provider record lists him as inactive with Pittsburgh as of 18 August 2026; his most recently verified major-league context is the Pirates’ 2026 roster. Publicly available sources do not establish a current active roster placement beyond the supplied provider status.
His first major professional breakthrough was his 2025 minor-league relief season. Pittsburgh reported a 0.74 ERA over 61.0 innings, the best mark in Minor League Baseball among relief pitchers with at least 60.0 innings, together with 18 consecutive scoreless innings. This performance preceded his addition to the Pirates’ 40-man roster and his MLB promotion in May 2026.
The Pirates reported a 0.74 ERA across 61.0 innings as a minor-league reliever in 2025, described as the lowest qualifying relief-pitching ERA in Minor League Baseball and the lowest such mark since 2019. MLB’s official player page lists his 2026 regular-season major-league line as 13 games, 14.0 innings, 0–0 record, 5.14 ERA, 17 strikeouts and a 1.86 WHIP. No individual MLB award has been verified.
MLB debut for Pittsburgh on 13 May 2026 against the Colorado Rockies; became the first Australian-born player to appear for the Pirates. His mother attended after travelling from Brisbane, and MLB reported that the occasion marked their first meeting in two years.
