Williams then completed his hat-trick on the hour mark to notch his 19th goal in 17 games. A quite remarkable scoring run which sadly he couldn't match at subsequent spells at the club.
A minute later Steve Heard scored when played through by Cliff Hercules and Heard added Aylesbury's fifth from a similar position nine minutes later.
Odegbami hit his side's third late on but it was only a consolation.
