Right-back Alex penned his first professional contract midway through his final year as a scholar.
The defender signed a two-and-a-half-year deal in January 2023, committing his long-term future to the club after impressing academy staff both at U18s and U21s level.
Although other defenders gained more opportunities down the right side of defence during Alex's final scholarship term, the Warwick-born youngster gained plenty of minutes with Leigh Downing's team in the U18 Premier League. Williams made 17 appearances in the 22/23 campaign, registering three assists.
Williams is an enthusiastic defender who plays with confidence, energy, and is a great crosser of the ball.
The Baggies youngster, who operates from right-back, has been an ever-present in the club's Under-18s and produced several eye-catching performances in Richard Beale's PL2 side during the 2021/22 season.
Alex excelled during an away defeat to Southampton for the Under-23s and went onto rack up five appearances in the PL2 team over the 2021/22 campaign, while featuring in 20 matches for the 18s.
The defender has also represented Wales at Under-17s level.
