Striker Zan Vipotnik scored for Swansea City in both normal time and the penalty shootout
Andy Fisher's save from Matthew Sorinola helped Swansea City to a penalty shootout win over Plymouth Argyle and put them through to the third round of the EFL Cup.
Fisher's save from ex-Swansea player Sorinola was the only miss in the shootout after the game had finished 1-1 in regular time.
Sweden midfielder Melker Widell struck the decisive penalty after successful kicks from Zan Vipotnik, Ethan Galbraith, Liam Cullen and Ben Cabango.
Earlier, Vipotnik had given the home side the lead with a 25-yard strike that went in off the underside of the crossbar midway in the first half.
It was the Slovenia international's second goal in successive games, having come off the bench to earn a point against Watford in the Championship last Saturday.
But a resilient Argyle drew level a minute before half-time when defender Brendan Wiredu outmuscled Widell in the Swansea penalty area to head home Sorinola's free-kick.
The equalizer shocked the home crowd and came after Argyle goalkeeper Luca Ashby-Hammond had denied Swansea - and Vipotnik - a second goal with a save from close range after initially being rounded by the Swans number nine.
That was one of many Swansea chances - including an opening minute one-on-one with the keeper from Widell and a free header in the box for substitute Malick Yalcouye.
Argyle forward Bim Pepple had two superb opportunities to give his side the lead. The first was a close-range effort which was saved by Swans keeper Andy Fisher, who then a missed chance to score on the goal line from the resulting corner.
But it was Swansea who triumphed in the shoot-out to maintain their unbeaten start to the season at home.
What they said
Swansea head coach Alan Sheehan:
"We asked to get through to the next round and we got the job done. I think we made it more difficult than we perhaps should have. In the first half I was happy with a lot of things - we controlled the game for 43 minutes until the set-piece which was obviously disappointing and then Plymouth came out on the front foot and it became a bit of a basketball game. But ultimately we stayed in the game and got through to the next round."
Plymouth head coach Tom Cleverley:
"It was a terrific performance, we're in a moment where we don't seem to be getting what we deserve right now but it's important the players keep believing in the right things, the right processes, and eventually that will bring results. I thought they were fantastic tonight."
