West Brom went temporarily top of the Championship with a win over in-form Queens Park Rangers at the Kiyan Prince Foundation Stadium.
Teenager Nathan Ferguson opened the scoring before the 2-0 victory was sealed when Matheus Pereira scored from a free-kick.
The Baggies remain the only unbeaten side in the Championship as Slaven Bilic’s side are flying at the start of the season.
Ferguson has caught the eye under boss Slaven Bilic this season and enhanced his growing reputation with a terrific performance and goal.
His all-important opener came eight minutes into the second half and was no more than Albion deserved.
They were the better side during a scrappy first half in which Charlie Austin had an effort saved by Lumley and was just unable to get to Grady Diangana’s low cross.
Austin, playing against his former club as were Darnell Furlong and Matt Phillips, was given a warm reception by the home crowd before kick-off and when substituted on the hour mark.
The striker, signed from Southampton during the summer, is still waiting for his first league goal for Albion. That wait will surely not last much longer in a side with plenty of fluency going forward.
QPR, on the other hand, struggled to create clear-cut chances and rarely looked like finding an equaliser once Ferguson had broken the deadlock in emphatic fashion.
Rangers had won their previous four league games and they too would have gone top with a win, but they were second best throughout.
Ilias Chair shooting over was a rare moment of concern for Albion, who always looked threatening at the other end.
Shortly before being substituted, Austin saw a deflected shot pushed away by Lumley, who also kept out a strike from Diangana and denied substitute Kyle Edwards at point-blank range.
Lumley was unable to keep out Pereira’s free-kick but did produce a fine save to prevent a third when he clawed away Robson-Kanu’s header.
