So that idea came to my mind. It is not necessary to make it happen. Just saying.
What if someone has 0/3 and he gets a kill the announcer says: Comeback! or something like this. You know, just how she says Killing Spree when someone gets 3 kills? Something like that.
TL;DR: When someone is on a death spree of 3 deaths and gets a kill, the announcer says something like Comeback!
