The Belgian, who is competing at his first Ryder Cup, won the match against Woods and partner Steve Stricker on his own, with playing partner Lee Westwood not contributing a single hole.
Speaking of Colsaerts display, Woods said: "That's probably the best putting display I have ever seen.
"We ran into a guy who made everything today. I don't know what he shot.
"He was like seven under through 10. I quit counting after that."
Woods has since been dropped for today's morning foursomes but Colsaerts has been given the nod and will partner Sergio Garcia.
