welcome back. for the first time in eight years an american is waking up as indy 500 champion. ryan hunter-reay crossed the line a half car ahead of helio castroneves. it was the second-closest finish in indy 500 history. when he got out of his car, hunter-reay called his win a dream come true. >> it hasn't sunk in. it is the most fantastic team. the support they have given me, to give me the race car two years in a row to have a shot at winning the greatest race in the world. a dream has come true today. i'm a proud american boy for sure. >> he got to take the traditional swig of milk after he crossed the line. just .06 of a second from the guy behind him. >> that is amazing. the lead is traded throughout
