Our American international played every minute of our 41 games in 2002-03 - the first time he'd managed the feat in his career.
His coach Hans fully appreciates the achievement after 18 years as a professional himself and the rigours of goalkeeper training day in, day out for 10 months.
"The fans only see one thing and that's matchdays," said Hans. "But the keepers during the week work really hard, throwing themselves left, right and centre five days a week.
"It is the most physical training, hitting the ground day in, day out.
"So to keep it going and be ever-present is quite an achievement for Kasey. I've done it myself and you can pay with niggling injuries, but generally Kasey has been fine and that's testament to him.
"I've been very pleased with him. He's obviously made one or two mistakes, we all do, but he's kept them to a minimum over the season and kept us in a few games as well. I'm delighted and I'm sure Kasey is as well."
