The Pilgrims conceded four times in a decisive 11-minute spell before the break, with Ryan Jones, Brett McGavin, James Daly and Johl Powell all on target.

Substitute Mason Obeng added a fifth in the second half before Powell scored his second, from the penalty spot, after Gavan Holohan's foul.

Louis Chadwick, following on from his heroics at FC Halifax Town on Tuesday evening, produced early saves to deny Powell and twice from Slavi Spasov.

Home keeper Jos Barker made a good stop to deny Terrell Agyemang from distance - and it laid the platform for the Glovers' onslaught at the end of the half.

Town took a 34th minute lead when JONES waltzed through to get the better of Georgie Gent and Jamie Grimes to slam the ball past Chadwick.

McGAVIN added Town's second three minutes later and DALY had the freedom of the back post to angle home Yeovil's third in the 42nd minute.

POWELL wriggled through in stoppage time to add Yeovil's fourth - and leave the travelling contingent stunned.

Sub OBENG steered home number five in the 73rd minute and United's woes were compounded three minutes later when Holohan gave possession away, brought down POWELL and the same player stepped up to roll home Town's sixth.
