Born on 17 March 2003 in Oostvoorne, Youri Baas is a Dutch centre back whose steady progression from local youth sides to Ajax first team has made him a notable name in modern Dutch football. Featured here on Walkouts, his profile combines on-field credentials with clear provenance, appealing to collectors seeking signed shirts and authenticated memorabilia tied to a recognised career trajectory.
Baas began his football education locally with OVV before joining the youth ranks at Excelsior in 2012. A move to the Ajax academy followed in 2017, where he developed through successive age groups and adapted to Ajax's technical, possession-based approach. His pathway mirrors the club's emphasis on academy talent and provided the platform for his first professional minutes.
He made his official debut for Jong Ajax as a substitute in a 2-2 draw against De Graafschap on 11 December 2020, and a contract extension on 26 March 2021 confirmed the club's belief in his potential. Baas took his next steps into senior football with an Ajax first-team debut on 28 August 2022 in an Eredivisie win over FC Utrecht, and he featured across domestic and European fixtures during the 2022 to 2023 campaign.
Seeking regular senior minutes, Baas spent the 2023 to 2024 season on loan at NEC, where he emerged as an influential presence at the back. He made 27 league appearances and scored 3 goals, performances that helped NEC reach the KNVB Cup final, finishing runners up to Feyenoord. The loan season provided sustained match exposure and useful additions to his statistical record.
Returning to Ajax for the 2024 to 2025 season, Baas established himself as a regular starter, often deployed on the left side of central defence. He featured in European competition, including a notable UEFA Europa League group stage match away to Slavia Prague on 3 October 2024, where he was sent off after receiving a second yellow card. Ajax confirmed a new contract extension on 20 December 2024, tying him to the club through to 30 June 2028, a factual milestone that cements his short term future at the club.
On the international front, Baas represented the Netherlands at youth level, including seven caps for the Under 17s, and earned his first senior squad call up in March 2025 for the UEFA Nations League quarter finals against Spain on 20 and 23 March 2025. Those selections underline his rising national profile.
For collectors, the direct links between match milestones, club confirmations and national selection provide clear provenance for memorabilia. Signed shirts, authentic autographs and match issued merchandise tied to documented dates and appearances are central to collector narratives. Items connected to recognisable events, such as a first-team debut, a cup final appearance or a contract announcement, carry crisp provenance and appeal to those assembling modern Ajax collectibles.
As a young centre back with a steady record of development and documented appearances across domestic and European competitions, Baas offers both a sporting storyline and collectible relevance. His ongoing role at Ajax and national recognition suggest a continuing trajectory collectors will follow, and Walkouts remains a source for authenticated Youri Baas memorabilia that links provenance to each item.
