What is katniss's trainer's name?

Haymitch Abernathy is a former District 12 tribute and winner of the Hunger Games. He is pretty much a drunk who is asked to come out of his alcoholic stupor long enough to coach Katniss and Peeta to victory in the Hunger Games.

This question is so easily answered that I must ask if Catalina P. has read the book. It is a complete improbability that such an integral character as Haymitch could be forgotten.
