Neil Kilkenny scored a superb goal and Luciano Becchio missed a penalty in Tuesday night's League One clash as Yeovil player-manager Terry Skiverton was left still searching for his first win in charge.
Beckford opened the scoring in the 26th minute when a telegraphed pass was seized on by Ben Parker who hoisted the ball into the penalty area for Beckford to stick out a boot and divert the ball past unguarded keeper Josh Wagenaar.
Beckford had a goal disallowed for offside almost immediately but Yeovil fell further behind to Kilkenny, who spotted Wagenaar off his line and lobbed him from 30 yards in the 43rd minute.
Kilkenny put Beckford through for his second goal in the 52nd minute and the former Weadstone striker completed his hat-trick six minutes later after being released by Jonny Howson - his 28th goal of the season.
Becchio was brought down after 71 minutes but fired his penalty high over the bar.
