Middlesbrough came back from a goal down but were left frustrated as a resilient West Brom claimed a point at the Riverside Stadium.
The in-form Baggies started the game stronger and took the lead from their first attack as James Morrison fired home from long range after the home side had failed to clear a free-kick.
But Boro levelled soon after through Alvaro Negredo's penalty after the Spain striker had been fouled in the box by Gareth McAuley.
From that point on, Aitor Karanka's side looked the more likely to win the game, although West Brom twice hit the woodwork through headers from Craig Dawson and Matt Phillips.
