Birmingham City made it five games unbeaten in the Championship with an impressive 3-0 win over QPR.

In-form Liam Millar scored in both halves for Blues before substitute Demarai Gray's stoppage-time effort sealed a third straight win for Chris Davies' side.

Only goal difference separated the teams before the game but QPR, themselves unbeaten in five heading to the West Midlands, offered little to preserve that run.

Birmingham stay in fourth place as their strong start to the season continues, while the R's slip out of the play-off places to ninth.

The visitors wasted a huge chance to take the lead inside the opening 10 minutes when defender Boy Kemper failed to connect with a flick-on from a long throw at point-blank range.

With chairman Tom Wagner watching on, Blues started confidently after Tuesday's 4-0 win over Preston and their speedy attack was in full force when the in-form Millar gave them the lead following a counter.

Millar, on loan from Hull, found the bottom corner for his second goal in as many games after he was sent through one-on-one after 27 minutes.

Blues needed just four second-half minutes to double their lead, with Millar again finding the net after finishing another breakaway move.

Home goalkeeper James Beadle was forced into action just after the hour mark to tip an effort from Ronnie Edwards around the post as the R's enjoyed their first sustained spell of pressure in the match.

At the other end, Millar might have had his hat-trick but fired straight at QPR keeper Pierce Charles when well placed.

His replacement Gray wrapped up another good day at the office for Blues when he blasted the ball high into the net from close range late on.
