Rob Hulse scored his first goal since November to help West Brom to a comfortable victory over Coventry.
Horsfield opened the scoring
His striker partner Geoff Horsfield opened the scoring when he muscled Steve Staunton off the ball to rifle home from the edge of the 18-yard area.
Hulse then doubled the lead after the break when he fires high past Scott Shearer after the keeper had made a great save from Horsfield's volley.
Mark Kinsella secured the win with turn and strike from eight yards out.
It was not long before the Baggies attack began to test the Sky Blues shot-stopper.
The 22-year-old kept out a good low 18-yard drive from the boot of the Hulse with 10 minutes of the match gone.
Moments later, Horsfield had a golden opportunity to put his side ahead. The former Fulham forward had the goal at his mercy when he collected a Thomas Gaardsoe headed pass from a corner, but mis-kicked at the crucial moment.
But the burly striker made amends midway through the first-half when he picked up a diagonal pass and muscled Coventry defender Steve Staunton off the ball to fire home through the legs of the unlucky Shearer.
Coventry may have deemed themselves unlucky having gone behind, but they did nothing to help their own cause and were limited to half-chances.
Liverpool on-loan player Stephen Warnock came the closest when he headed over after eluding his marker inside the six-yard area.
Things went from bad to worse for the visitors after the break.
With seven minutes gone, Horsfield beat Staunton yet again but saw his stunning volley brilliantly palmed away by Shearer.
But the keeper could little with the follow-up as Hulse pounced first from the resulting cross to rifle in from the edge of the 18-yard box.
Coventry huffed and puffed in search of a reply, but for all their pretty play in midfield they failed to make sufficient in-roads into the West Brom defence.
With 11 minutes of the game remaining Republic of Ireland midfielder Kinsella turned inside the penalty area to fire past Shearer and keep his side firmly in the hunt for automatic promotion to the Premiership.
