Kasey describes the ball as 'strange' and insists is does the keepers no favours at all.
"I'm hating this ball, to be honest," Kasey admits.
"It's a strange, strange ball. It's really weird and you have to do things in a certain way. If you don't hit that ball perfectly it just doesn't go anywhere and if you hit it too well it goes too far.
"It's just not a very forgiving ball.
"I think it's actually heavier than usual and if you hit it well the momentum takes it and if you don't it really doesn't shift.
"If you watched our game against Portugal, Brad and some of our defenders were hitting the ball real well and Baia was topping everything and it was dying before midfield.
"It's one of those balls that, on the day, if you're feeling it and making good contact it's just going to take off. Then on another day if you're timing is a bit off it just goes nowhere."
David Seaman said he was having difficulties with the colour of the ball - one he described as 'skin' - explaining that it is harder to pick out in flight.
"We've been training with it for quite a while and that has helped. I know when I first starting playing with it I found exactly that," agreed Kasey.
"I played in Germany and had a good game, but the first few days was really strange trying to pick up the ball.
"It's a funny ball and it's definitely going to cause a few issues."
So why, ahead of major tournaments, do unfamiliar balls come into play?
"Who knows? Marketing my friend, marketing..."
The World Cup ball has attracted a fair amount of negative comment during the tournament, particularly from the goalkeeper's union - and our Kasey goes along with the party line.
