Swansea City maintained their unbeaten start to the season despite being frustrated by Wrexham in a goalless Welsh derby that failed to truly catch fire.
Vitor Matos' side, who stay top of the Championship, again caught the eye and enjoyed the majority of possession.
But they failed to notably trouble their disciplined visitors who had the game's two biggest chances to break the deadlock.
They spurned both second-half opportunities, with debutant Callum O'Hare shooting narrowly wide and Max Cleworth failing to connect when just yards out.
Substitute Zan Vipotnik came closest for Swansea, although not even last season's Championship top scorer could provide the game with the breakthrough, with bragging rights at stake.
It did mean Swansea moved a point clear at the top before their trip to Southampton on Tuesday, as well as keeping up an impressive defensive record that has seen them only concede once in their opening five games.
And Wrexham, having won their first game of the season in midweek at Millwall, will draw positives as they look to build towards games with Burnley and West Ham over the next week.
That looked in some doubt with the way Swansea started, penning Wrexham in and troubling defenders without really working the goalkeeper.
Having kept the threat at bay during a first-half dominated on the ball by the hosts, it was clear just minutes after the restart that Swansea would face a more aggressive opponent as debutant O'Hare fizzed just wide from a Sam Smith knock-down.
Swansea did respond, Moussa Yeo not able to stretch to meet Josh Tymon's centre, but Wrexham's introduction of fresh wing-backs and attacking double-act Kieffer Moore and Josh Windass kept momentum the visitor's way.
Windass' 70th minute shot fired it's way through legs after a quick free-kick, but centre-back Cleworth could not react when he whipped his way a few yards from the line.
Swansea - who saw Ben Cabango booked for a wild challenge on O'Hare - revived to set up a tense finale, but Vipotnik could not have the final say as he failed to guide Moussa Yeo's cross past Anthony Patterson.
And when Lawrence Vigouroux reacted well to collect a Moore attempt in injury time, both sets of fans knew they had to settle for a share of the points and the Welsh pride at stake.
