How to handle a Fizz

Ran into one in Normals... got fed and annihilated the party. That invincibility was a pain in the arse and he got such a burst too.... Any way he can be handled when fed? Even Yasuo is manageable since he don't have escapes and vulnerable to melee and non-projectile attacks, but this little annoyance got ridiculous mobility too for both escape and engage.
