With Spurs leading, Kenna tried his luck on 68 minutes and his effort clipped Steffen Freund on its way goalwards - enough to send the ball beyond the outstretched hand of Kasey.
"I felt pretty confident coming into the game and I made a few saves," he reflected afterwards.
"With the goal, it took a bit a a deflection that took it around me. It was a good strike - but I think I would have had it without the deflection. These things happen though."
Even though three points was reduced to one with Kenna's leveller, Kasey insists that the important factor is that we didn't lose and are still on track for the unbeaten run the team are striving for.
"It was a nasty day, but I thought we battled pretty well. It was difficult to get the ball down and play in the conditions and they are an extremely hard working team at home.
"What we are trying to do is go on a long unbeaten streak and we came here looking for the three points, but we didn't lose.
"We now need to put on the same performance against West Brom as we did against Leeds and go from there."
Kasey Keller believes he would have saved Jeff Kenna's strike for Birmingham on Saturday had it not been helped on its way by a deflection.
