After joining the Scarlets in 2010, Williams made 30 appearances for Llanelli, including the 2012 Premiership Final against Pontypridd, and made his senior Scarlets debut in the LV= Cup match against the Dragons in February 2011.
Owen was a member of the Wales Under-20s squad that finished third in the 2012 IRB Junior World Championships in South Africa. Although he did not play for the Scarlets at all in 2011/12 as he gained more experience in the domestic Welsh league, he clocked up 14 games in 2012/13 including the man-of-the-match performance against Tigers.
After 81 appearances with the Tigers, Williams was signed by Gloucester Rugby for their 2017/18 season.
Williams has been included in Wales' upcoming 6 Nations 2017 squad. Owen will join up with the Wales squad for the summer tour. A prolific goal-kicker, Williams' ability to slot in at No.10 or 12 could well see a few first Welsh cap this summer.
Williams took his test cap tally to 3 in November and was named in the Wales 2018 6 Nations squad.
As of the 2018/2019 Champions Cup, Williams has had 25 European Cups appearances scoring 3 tries and 170 points.
