Stunning long-range strikes from John Swift and Darnell Furlong helped West Brom coast to their first Championship win of the season as they ended Hull City's unbeaten league start in fine style.
The Baggies, in the bottom three prior to kick-off, struggled to create chances early on and could easily have trailed but were ahead at the break through Callum Elder's unfortunate own goal.
Steve Bruce's increasingly confident side doubled their lead within three minutes of the restart, Swift striking home his second goal of the season from the edge of the box before Furlong made it 3-0 with another sumptuous long-range shot.
