Despite their lead, the Brits still had work to do on Sunday when Harriet Dart lost to Paula Badosa 7-6 (8-6), 6-7 (7-5), 1-6.
Dart belied their world rankings of No. 98 to push Badosa to the top, at one point just two points from winning the game in a thrilling tie-breaker in the second set.
But the No.13 steeled itself when it mattered most, running away in the third set to put Spain back in the tie.
While Nadal waited in the wings for a potentially crucial fifth rubber, much hung on what Ramos-Vinolas, a replacement for Pablo Carreno Busta, could do against Evans.
After a sluggish first set, the Spaniard revived in the second set and Evans, a disappointing first loser to Aussie Jason Kubler, looked nervous going into the third set.
However, the world No. 27 secured a crucial break in game seven and eventually served out the contest with a 6-3, 1-6, 6-3 win, making the mixed doubles a dead rubber.
“I don’t feel my strongest, but I have a great team behind me,” Evans said.
“It helps that it’s not a regular tournament; It’s hard to throw in the towel when you’ve got so much behind you.”
Petra Kvitova earlier defeated Laura Siegemund 6-4, 6-2 to secure her second consecutive win of the tournament as the Czechs took a 3-0 lead in a draw against Germany.
