Substitute Jack Marriott came off the bench to grab a late brace as Luton earned a 2-0 win over 10-man AFC Wimbledon.
The young striker produced two prolific finishes from close range inside the final 12 minutes after the visitors had to play with a man short for almost an hour after Karleigh Osborne was sent off.
Before going down to 10 men, Wimbledon had looked the more likely, George Francomb testing Mark Tyler from 18 yards and Adebayo Akinfenwa looping a header over.
Tyler made a fine stop from Francomb's deflected long-ranger as home striker Josh McQuoid glanced a header narrowly wide.
Tyler produced an even better stop from Andy Barcham's effort at the near post while Craig Mackail-Smith shanked well wide from a rare opening.
However, Osborne then picked up two bookings in the space of five minutes to see red after 35 minutes.
Paddy McCourt shot over the top while in the second period substitute Sean Rigg fired across goal and Scott Griffiths' angled drive was touched behind by James Shea.
Tyler was called upon again, saving brilliantly from Rigg, before Marriott tapped home after a goalmouth scramble after 78 minutes and he was at it again in stoppage time, firing home once more to seal another welcome Hatters victory.
