Steve McNulty: 8 - Dominant centre-half was far too powerful and strong for ineffective Boro.
Jake Howells: 8.5 - Rejuvenated wide man got plenty of joy on the left as he gave the Hatters real width.
Scott Griffiths: 8 - Experienced full-back timed his tackles well and overlapped to good effect.
Ryan Inniss: 8 - Giant on-loan Crystal Palace youngster was unlucky to see a header cleared off the line as he formed a fine partnership with McNulty.
Cameron McGeehan: 7.5 - All-action Norwich City midfielder showed some real bite in the tackle and plenty of potential for the future.
Luke Guttridge: 7.5 - Struggled to find his stride in the first half, but Luton’s threat grew as he became more involved.
Matt Robinson: 7.5 - Young midfielder started slowly, but grew in confidence and influence.
Ronnie Henry: 7.5 - Reliable skipper put in a disciplined all-round performance that was too much for Boro.
Paul Benson: 8 - Knits everything together so well and is the perfect foil for Gray.
Andre Gray: 9 - Livewire striker took his hat-trick brilliantly as he showed why he is the premier striker in the division.
Mark Cullen (sub): 6.5 - Gave Benson a well deserved rest as he came on as a late sub and almost scored.
David Martin (sub): 6 - Looked keen to make an impact and saw one effort soar over the bar.
