Albion Under-21s were held by Swansea City in their penultimate Premier League Cup group clash on Friday night.
A late Reyes Cleary penalty appeared to have sealed all three points, until Swansea scored in the dying embers to restrict Richard Beale’s Baggies to a draw.
The result leaves Albion third in Group C with six points heading into deciding tie against Fleetwood Town on the final day of January.
Winger Ollie Bostock sent the Baggies flying out of the traps with attacking intent, rattling the woodwork twice within the first seven minutes of the tie, while Harry Whitwell blazed over from inside the penalty area.
The hosts were reduced to ten just before the half-hour mark. Target man Eseosa Sule appeared to be through on goal, before being taken down by Swans defender Sebastian Dabrowski.
With Albion keen to take immediate advantage of the man advantage, Deago Nelson was played into space by Bostock before drilling wide of the mark.
Sule looked to have made the breakthrough just before the half-time whistle but his goal was ruled offside by the linesman.
The Glaswegian almost grabbed the opener following the restart too, this time being denied by the onrushing Evan Watts, who closed down the angle well, while captain Reece Hall also fired over from just outside of the six-yard area.
Though down to 10, Swansea remained a threat on the break and forced a strong stop from Ben Cisse, who reacted sharply to deny Glory Nzingo and then Aimar Govea in quick succession.
Substitute Cleary dispatched a penalty in the latter stages of the tie, which looked to be the decisive goal until Sammie Henia-Kamau notched an equaliser to leave Group C in the balance heading into the final matchday.
Albion: Cisse, Nelson, Hall, Mfuamba, Dupont, Shaw (Humphries 64’), Crowther, Iddrisa (Cleary 59’), Whitwell, Bostock (Chimeziri 74’), Sule (Higgins 74’).
