The Championship's top two teams played out an entertaining 1-1 draw at The Hawthorns as Semi Ajayi found the net at both ends.
The giant defender gave Albion the best possible start when he poked home from a corner only 90 seconds into the first half.
Leeds looked to press forward on the counter-attack but it was Albion should've extended their lead.
Firstly, Matheus Pereira's free kick was palmed around the post by Leeds' keeper Kiko Castilla. Then, Matty Phillips wasted Albion's best chance to score a second when he raced clear but could only fire his shot at the feet of Castilla.
United made two changes at half time with former Wolves defender Barry Douglas coming on alongside Patrick Bamford. The change worked almost immediate as United attacked down their left with Bamford's header deflecting in off Ajayi to level the scores.
Albion came closest to snatching a late winner when Kyle Edwards' dipping effort was tipped over the bar but neither of the promtion rivals could find a second.
The draw means both sides are locked at top of the division on 52 points from 26 games. United stay top courtesy of a slightly better goal difference.
