WITH Friday's Under-23 Premier League Cup game at Fulham in mind, Argyle fielded a particularly young side for this EFL Youth Alliance League game in Wales.
Yet, it was the Pilgrims who took a tenth-minute lead after a right-wing cross found Reuben Collum at the far post to play the ball back for top scorer Rubin Wilson to steer home from close range.
That was as good as it got for Argyle as their hosts hit back, with two goals on the counter-attack, to go in at the break leading 2-1. The second half saw Argyle enjoying more than their fair share of the possession without ever troubling the home goalkeeper.
It was Newport who were to show Argyle the way to goal as they extended their lead with a fierce 25-yard free-kick that flew high into the centre of the goal.
Argyle almost hit back but Wilson's header crashed back off the crossbar and with the game in the final minute, it was the home side that struck again as the Pilgrims failed to clear a corner for Newport to scramble the ball over the line.
Argyle: Tyler Coombes, Isaac Burdon (Ollie Tomlinson 65), Ali Mansaray, Brandon Pursall, Reuben Collum, Angel Waruih, Carlo Garside, Charlie Miller (Jarvis Cleal 75), Jeremiah Medine, Rubin Wilson, Rhys Shirley (Scott Crocker 55). Substitute (not used): Harry Townsend.
