It was a low-key opening first half-hour, notable only for a decent reaction stop from Ian Lawlor - making his first league start in 21 months - as he pushed a Lamine Fanne attempt over the bar.
Rovers just couldn't get going down the other end and just before half-time the hosts went in front as the visitors concede from yet another set-piece. Luton skipper Kal Naismith headed home unmarked from a free-kick taken on Rovers' left. Just moments later the hosts had a golden chance to double their lead when Jamie Sterry clumsily bundled over Nahki Wells in the area. Wells then stepped up but saw Lawlor deny him with a terrific diving save to keep out his penalty.
The visitors, in truth, struggled to fashion anything close to an equaliser. A Glenn Middleton free-kick was charged down whilst Luke Molyneux fired a shot straight at Josh Keeley as the hosts held on.
Here's the Rovers player ratings from Kenilworth Road:
13. Ben Close 7
Came on at the interval and immediately upped the tempo with a selection of nice passes dished out. Did his chances of a starting role no harm at all on this showing. Photo: Craig Hawkhead / AHPIX LTD
14. Toyosi Olusanya 4
Botched a brilliant chance when Gibson fed him not long after coming on, but his touch was way off it. Then showed a nice bit of pace as he burst past a few players before blazing a shot over. Photo: Howard Roe/ahpix.com
15. Jordan Gibson 6
Led the charge on a super-quick counter as he teed it up for fellow sub Olusanya. One of the few bright sparks for Rovers. Photo: Howard Roe/ahpix.com
