Gold Coast product Jack Sinfield won a rookie spot on the Queensland contract list ahead of the 2022-23 summer after being part of the Australian side that finished in third place at the 2022 Under-19 World Cup.
The off-spinner made his Marsh Cup debut in February 2023 and a week later made his Marsh Sheffield Shield debut for the Bulls against NSW at the Gabba.
Although Sinfield didn't feature for the Bulls in either format during the 2023-24 summer, he was upgraded to a full Queensland contract for the 2024-25 season.
