The Swede was left out of the middle day's play just like Martin Kaymer, but while the German came back to hole the all-important cup-winning putt in the singles Hanson lost to Jason Dufner and so was the only European not to contribute something toward the team total.
"The Ryder Cup kind of hurt my confidence a little bit," he said today [Thursday] after starting the Dunhill Links Championship at Carnoustie with a level par 72 on his 35th birthday.
"I came in full of confidence after the win in Holland and played really well during the practice rounds. I was feeling great and just wanted to get out there and play.
"When I didn't get to play more than 14 holes on the first couple of days (he and Paul Lawrie lost their fourball 5&4 to Bubba Watson and Webb Simpson) that really got to me.
"I think that hurt my performance a little bit on the Sunday, even if I shot a couple under.
"I think to put on a really good round on Sunday I would have needed to play a bit more."
Asked if he spoke to Olazabal, Hanson added: "I did a little bit, but it's hard. You're part of a team and when I got notified 20 minutes before we teed off on Saturday I got very upset.
"I didn't take that very well, but I just locked myself in a dark room and stayed there for a couple of hours.
"You don't want to let your bad feelings affect the other guys. It's all about getting out there and supporting your teammates, so I was out there Saturday afternoon walking the fairways.
"I think in that respect I didn't damage the team and that was the main thing. You can't let your ego affect the rest of the team.
"I was so sure I was going to play, so I actually went out and played a couple of holes Saturday morning and did my warm up early in the day.
"When I got notified I was actually filling in the pinsheet (hole positions) in my book, so that's probably why I got so upset. I was already in game mode."
