Four quickfire goals in 20 minutes from Zane Banton, Jemale McKenzie-Lowe, Arel Amu and Isaac Galliford saw Luton defeat the Pilgrims and progress to the second round proper on a wet Wednesday evening at The Jakemans Stadium.

Boston did have their chances with Aaron Eyett having a 25-yard free-kick tipped over the bar by Luton keeper Ben Barnes. After the break Louis Saebe, who tried to create all game against a physical Luton defence, skipped beyond his marker and hit a strike from the edge of the penalty area which looked destined to bend into the net.

But Barnes again pulled off a top one-handed stop to match the brilliance of Saebe’s effort and after a spirited second half performance from United, Miles Lynch was sent off for a crunching challenge.

Luton held firm to seal a trip to Gateshead in the second round.

Boston (4-3-3): Sam Vince; Daniel Worthington (Billy Hodgkiss 74), Josh Spencer, Ollie Price, Jordan Sowerby; Miles Lynch, Jacob Pease, Aaron Eyett; Leon Squire (Liam Moran 70), Louis Saebe, Bradley Easey (Steven Dovey 80). Subs (not used): Joe Searson, Juris Kormis.
