The 20-year-old has been training with the Blades and recent reports suggested he had impressed coaches while on trial.
He has now put pen to paper on a deal at Bramall Lane and will initially link up with Gary McSheffrey’s under-21s.
Baptiste had been a free agent since the end of the 2023/24 season, when he was allowed to depart Manchester City. He reportedly spent time on trial at Portsmouth in the summer but a move to Fratton Park did not materialise.
A ball-playing centre-back, Baptiste was nurtured within the famous youth system at West Ham. He was fast-tracked through the age groups, debuting for the club’s under-23s at the age of 15.
When the defender aged 17, West Ham offered him a professional contract, and in January 2021, he made his senior debut in an FA Cup victory over Doncaster Rovers.
Last year, he moved from West Ham to Manchester City, although he struggled to establish himself in the senior lineup at the Etihad Stadium. He played for Lommel on loan in Belgium while he was registered at the Etihad Stadium.
Having played for England at the under-16, under-17, and under-19 levels, he also has international experience on his resume.
