The home side did indeed take the lead in the latter stages of the first period when Mikel Balenziaga could only turn into his own net from close range.
Valladolid had their equaliser after 71 minutes when Oscar Gonzalez whipped a powerful effort into the top corner. There was time for late drama, however, with Jonas heading home in the final minute to hand Valencia the three points.
