United's under-23s drew 1-1 at the Bradley Community Stadium - with Trialist on target from the penalty spot in the 22nd minute, following a foul on Aidan Durkan.

Ex-Pilgrim Dayle Southwell levelled with a powerful free-kick after the break and Borough finished with 10 men following Reece York's straight red card.

Goalkeeper Alex Barker saved brilliantly to deny ex-Pilgrims Josh Venney and Paul Walker in the shootout, with Sam Warburton, Will Langford, Rufus Brooks, Jake Thompson and Durkan all on target for the visitors.
