Great Britain's opening tie at the Davis Cup finals will go down to a pivotal doubles rubber after Dan Evans lost to Dutchman Robin Haase in Madrid.
British number one Evans looked on course for a one-sided win before Haase fought back to win 3-6 7-6 (7-5) 6-4.
Haase levelled the tie after Andy Murray said he "didn't deserve" to beat world number 179 Tallon Griekspoor.
Jamie Murray and Neal Skupski are set to play in the deciding doubles later on Wednesday.
Andy Murray had survived a scare to put Great Britain ahead when he beat Griekspoor 6-7 (7-9) 6-4 7-6 (7-5) .
