Barnsley have completed the signing of Jason McCarthy, who has swapped Southampton for the Championship side for an undisclosed fee.
The 21-year-old had been at his hometown club since linking up with their youth team in 2002, and made his only Premier League appearance as a late substitute against Crystal Palace in 2014.
He has since found regular action on loan at both Wycombe Wanderers and Walsall, and will now hope to do so again after signing a three-year contract with the Tykes.
“I’m really, really pleased to get Jason to join us,” Barnsley boss Paul Heckingbottom told the club’s official website. “As soon as we became aware that there was a chance, we jumped at it.”
McCarthy, who operates in a right fullback position, becomes the second new arrival at Oakwell this summer following Stevie Mallan, who joined from St Mirren last month.
“I’m absolutely delighted to be here, it’s a thrill to get it over the line,” said McCarthy. “This was the perfect next step for me, to sign for a Championship club, especially one like Barnsley.”
