The deal runs until 2027 with the option of an additional year. The midfielder joined the Reds last summer from the FAW North Academy, initially representing our Under-21s side.
She made her first-team debut during our Adobe Women’s FA Cup fifth-round victory over Wolverhampton Wanderers, appearing as a substitute and scoring twice in a 6-0 win for Marc Skinner’s side.
Griffiths, who turned 18 in March, has been capped by Wales at both youth and senior level, playing for the Dragons against Italy in a Nations League fixture earlier this year.
After making a number of appearances on the bench for the Reds as an unused substitute late in the 2024/25 season, she’ll now be hoping to kick on having committed her long-term future.
