(6)Federico Delbonis def (WC)Nicolas Massu 6-1 4-6 7-6(4)
I only got to watch the third set and it was hard to tell who was going to win though Massu seemed really aggravated so it wasn't looking good. Then he argued with the umpire over what seemed to be about more than just what he thought was a bad line call. He even started to get in Delbonis face a little.
Then he calmed down and played better. It helped that Delbonis choked when serving for the match. Don't know what happened to Nico in that tiebreak though
