The Hatters were behind when Donervon Daniels put through his own net after 15 minutes, with home defender Semi Ajayi putting the game beyond them with 20 minutes to go. Here's how the Town players rated at the Hawthorns.
9. Kazenga LuaLua: 6.5
Led Lutons charge forward, as he caused the Baggies defence some headaches when turning and running at them. Once more though, final ball was lacking, while couldn't quite prevent Phillips' cross for the second.
10. Harry Cornick: 6.5
Well marshalled by the visitors defence for long periods, as they had the pace and awareness to cut out his danger. Still managed to escape their attentions now and again though, but just couldn't pick out a team-mate in the box.
11. James Collins: 6
Handed the captains armband and thought he had made it 1-1 in the first half, only to see the linesmans flag cut short his celebrations. Not too many clear-cut chances afterwards as the visitors defence tightened up.
12. Izzy Brown (SUB): 6.5
Got longer from the bench as he continues to build his fitness back up. Ghosted past a few opponents as if they werent there, but Baggies second with 20 to go blunted his impact.
