The Baggies conceded early to Yoan Gouffran but the decision to award a free kick instead of a spot kick for a challenge on Billy Jones denied the hosts a chance to draw level just before half-time.
While Clarke rued the decision, he accepted that his side were sluggish in their first game for two weeks.
|WRONGED BUT ON TOP
|PLAYER RATING | BILLY JONES
|Got forward well to support the attacking ranks and dealt well with everything defensively. Something of an unsung hero for the Baggies and his display was topped off with a deserved equaliser.|
"A draw was a fair result. They were quicker out of the traps first half and you could tell we haven't played many games recently.
"It's difficult chasing a game at this level but we made a tactical change at half-time and it paid off with an equaliser. We had a right go second half but couldn't quite get a winner."
Newcastle manager Alan Pardew was pleased with the commitment of his players but was left ruing the chances missed in the first half having seen his side squander a dominant position.
|BAGGED AND TAGGED|
|8/1||West Brom are 8/1 with BetVictor to finish in the bottom half of the Premier League|
"We had to have two sides because West Brom went direct the second half and it worked for them because they've got really powerful strikers and they started causing us a problem.
"I think, first half, we should have had two goals and that would have been enough but fair play to West Brom; they put us under a lot of pressure, a lot of corners and we had to play well. All parts of our team have played well."
