Kasey has only conceded six goals in as many games during that period, against teams including Leeds, Arsenal and weekend opponents Liverpool.
He stamped his mark on the game during the first ten minutes with a superb stretching stop to deny Liverpool captain Sami Hyypia's header from finding the back of the net.
"That makes it nice when you can get into the game nice and early," reflected the USA keeper. "I didn't feel the best during the warm-up, I don't know why, but to get a big save in early and then get a little lucky with a ball coming off the post - we seemed to settle down a bit after that.
"I was very happy with the way we came out in the second half and negated their chances a lot more than we did in the first.
"To do that against a team fighting for the title for the whole second half with a 1-0 lead is fantastic."
Kasey certainly appeared to have his eye in during the encounter, collecting crosses with ease and directing operations in front of him.
"I felt really good, like I said, once I got going. The pitch really improved from the last time we played here, especially on the first half side, and that was always nice.
"It worked out fantastically well, the only trauma really is handing the title to Arsenal, but that's not our problem.
"Fans want to see us win at home and hopefully next year we can be in a position where we can be challenging more."
Kasey Keller says a big early save against Liverpool on Saturday provided the platform for his first clean sheet since returning to the side.
