Only six minutes were on the clock at the Stadium of Light when Perry, under pressure, was forced to direct the ball back to his own goal. Trouble was, he made a slightly sweeter connection than he might have anticipated and, at one stage, it looked like Kasey was going to be beaten all ends up and the ball was going to fly under the crossbar.
Thankfully, Kasey backtracked with some speed, but then encountered another problem - his momentum would carry him over the line. Somehow Kasey did the sensible thing and caught the ball to prevent the initial danger then deliberately dropped the ball right on the line to stop himself getting on the scoresheet.
"That was a hell of a back pass!" reflected Kasey, who revealed that previous experience in Spain helped him to deal with the situation. "I saw the line and I started sliding over it and I thought I've got to drop this.
"I did it one time, I was playing Oviedo for Rayo on a real wet day and I came running back and slid to try and hook a ball off the line. It hit the post and came back and hit me in the stomach. It rolled into the goal and I couldn't keep it out.
"I've been really wary after that. I saw the line coming up and I knew there wasn't going to be anyone close enough. If I kept it out I knew I'd have time to pick it up after that."
Unfortunately, Kasey was unable to prevent Sunderland scoring two more conventional goals on a day where it didn't seem to happen for the team.
"No it didn't and it's frustrating," he added. "We felt, going there, that we definitely had a chance of picking up points.
"We had a few close scares in the first half and in the second we felt that we really had to take in on.
"We came out of the break a little bit flat but, in saying that, we had a great chance to take the lead.
"They came down and got the first one, then we gave the second away too quickly after that.
"They hit you real hard. You think you've got a good chance of getting back in the game as we have done in the past - but we gave that second one up way too quickly."
While Kasey Keller was naturally frustrated at conceding two goals at Sunderland on Sunday, he could afford a wry smile when looking back at nearly being beaten by a superbly executed lob - from Chris Perry!
