Albion lost their fourth consecutive game and made it five games on the spin after their 1-0 defeat to Leicester.
Here's what the press had to say about the Baggies' loss. Click on the link to read the full report.
Tony Pulis’s men have not hit the net in seven of their last eight games and the run is threaten to tarnish a campaign in which they have exceeded expectations.
Results elsewhere mean they remain eighth in the table but clubs are now beginning to queue up behind and the top half finish which looked certain only a few weeks ago is no longer so secure.
In truth they might consider themselves unfortunate to have been beaten here. Vardy, well marshalled for much of the game by Jonny Evans, made the most of his only real chance of the game after Rondon had presented Shinji Okazaki with the ball in the middle of the park.
Albion pressed for a leveller in the second half but never really looked like getting one as the visitors held out for a win which all but ensures their survival.
Jamie Vardy continued his red-hot run in front of goal as Leicester eased their Premier League relegation fears with a 1-0 win at West Brom.
Vardy made no mistake two minutes before half-time as Leicester won away from home in the top-flight for only the second time this season.
His strike was his 17th of the season, his third in the last four games and his eighth in 12 matches under the control of manager Craig Shakespeare. It was also the third successive game that he had scored at The Hawthorns.
While Vardy has hit form at just the right time, Albion have hit a losing habit and a goal drought.
Jamie Vardy always has a party at the Hawthorns and this latest strike surely ends any lingering relegation fears for the Premier League champions.
Vardy collected his third goal in three games at West Bromwich Albion, who have gone 465 minutes without finding the net, to ensure a memorable return for former Baggie Craig Shakespeare.
Albion have now lost four games in a row and are running on empty, while Leicester and Vardy have been revitalised since the controversial departure of Claudio Ranieri in February.
