The play-off champions seemed set to record a much-needed win as goals from Jamie Steer and Jeff Hoad saw Jim Lynch's side lead 2-0 with just nine minutes remaining. But the Devils defenceman Martin Lindman set up a tense finish by pulling one back before Steve Thornton broke Eagles' hearts with an equaliser just a second from the end to take the game into overtime.
Neither side could find the winner, the draw leaving Ayr needing Nottingham or Cardiff to lose their remaining three games if they are to go through.

Tomlinson doubled his side's advantage, and Rick Brebant gave Storm some breathing space with a third with three minutes of the second session remaining. Pietrangelo continued to foil the visitors, who leaked a fourth when Jeff Jablonski broke with three minutes left to beat Bruno Campese.
