Adam Jiricek

Adam Jiříček first drew attention as a junior defenceman with a scoring touch, born 28 June 2006 and developing through Plzeň's system. In 2022–23 he split time between Škoda Plzeň's under-20 squad and the Czech Extraliga, finishing the U20 campaign with 12 goals and 29 points in 41 games while adding two assists across 12 Extraliga appearances. He dropped back to the under-17 side for the playoffs, contributing 1 goal and 13 points in eight postseason games.

North American clubs showed interest: Jiříček was taken 19th overall in the 2023 CHL Import Draft by the Brantford Bulldogs of the OHL but chose to remain in Europe that season. His 2023–24 year was derailed by a knee injury sustained during international play in December, ending his season; prior to that he had registered one assist in 19 Extraliga games. That injury and his modest Extraliga totals tempered draft expectations.

At the 2024 NHL Entry Draft, St. Louis selected him with the 16th overall pick. He signed a three-year entry-level contract with the Blues on 2 July 2024. On 29 October 2024, St. Louis assigned Jiříček to the Bulldogs for the remainder of the 2024–25 OHL season, where he reunited with Tomáš Hamara, a teammate from the 2024 World Junior Championships.

Internationally, Jiříček has represented the Czech Republic at several junior events: he wore an alternate captaincy at the 2022 World U-17 Hockey Challenge, collecting a goal and an assist in six games; he earned a silver medal at the 2023 Hlinka Gretzky Cup; and he was part of the bronze-medal Czech team at the 2024 World Junior Championships, where he suffered the knee injury in the opening game against Slovakia and subsequently underwent surgery.

On the ice, his game blends offensive instincts developed in junior ranks with the responsibilities of a stay-at-home defenceman; off the scoresheet, he is the younger brother of Philadelphia Flyers defenceman David Jiříček.
