Millwall avoided a potential banana skin as they reached the FA Cup fourth round with a 3-0 win against Newport.
Matt Smith’s seventh-minute goal gave the hosts the perfect start at The Den, the striker poking home a corner.
Newport started the second half well and should have been level but Jamille Matt could not beat Bartosz Bialkowski.
And the League Two side were left to rue that miss as Connor Mahoney converted a penalty before Tom Bradshaw sealed the win for the Lions.
Smith, who made a name for himself in the FA Cup as he scored twice to knock Liverpool out in 2013, eased any early nerves with his goal and continued to cause the Exiles trouble until he was replaced on the hour mark.
Matt should have equalised with Newport’s best chance of the game and Padraig Amond almost levelled from the rebound but he could only hit the side netting.
It was not to be for Amond, who failed in his bid to score in a ninth consecutive FA Cup game having been chasing Stan Mortensen’s record of 12 successive games.
Instead the Championship side weathered the pressure from Newport before Mark O’Brien fouled Jon Bodvarsson in the area, and Mahoney confidently took his penalty to double Millwall’s lead.
And the result was put beyond doubt when substitute Bradshaw got on to the end of a low cross to deftly chip the ball beyond Tom King to book Millwall’s place in the fourth round.
Newport manager Michael Flynn told BBC Sport Wales: “The first two goals we conceded, it’s not good enough.
“The boys have worked so hard today, they all put a real shift in, the chances could have put us back in the game.
“It’s a little bit frustrating because the first 30 minutes of the second half I thought we were the better team, we played some really good stuff.
“But it was not to be and credit to Millwall.”
