The Waratahs have signed Warringah prop Rory O'Connor through to 2020.
Loosehead O'Connor has been on the NSW radar in recent seasons and played with the side in their preseason trial against the Highlanders this year but this is his first full-time contract.
The 24-year-old is a consistent Shute Shield performer and has been long earmarked as a potential player to take the next step.
O'Connor said he would embrace the chance to learn off Test players like Tom Robertson and Sekope Kepu especially.
“I’ve come through NSW club rugby and it’s humbling to now officially be part of the Super Rugby team," he said.
"I have a lot to learn and the prospect of playing alongside some seasoned Wallabies will really help my game."
“A lot of club rugby players are very committed to making it professionally in Australia which is shown through the strength of the Shute Shield.
"Although club rugby isn’t as elite as Super Rugby, the levels are united by a love of the game and commitment to Australian rugby."
NSW forwards coach Simon Cron said O'Connor's work at the Rats had stood out to him.
:Rory has had a very strong Shute Shield and has been playing at loosehead prop for a number of years,” Cron said.
“He has an extremely professional approach to everything he does.
"His work ethic around the park separates him from other props and we look forward to getting him into the NSW Waratahs environment and helping him to achieve his goals in Super Rugby.”
O'Connor will run out for the Sydney Rays in Saturday's clash with Brisbane City at Woollahra Oval.
