That result means that Europe trail 10-6 heading into today's 12 singles matches, facing a seemingly insurmountable task to keep their hands on the famous trophy.
"Ian Poulter gave us a chance last night," Olazabal told BBC Sport. "It's a slim chance and obviously it will be difficult, but it has been done in the past.
"I could have had any order today. I wanted to put the guys that are on fire, playing well, on those first spots and try to win as many points as possible. I rested Luke on Friday afternoon and told him he is one of my important men. Many of the others are big hitters who are in good form."
Poulter goes out second today against US Open champion Webb Simpson.
