I love to see Marin in this Davis Cup match, it's so visible what difference it makes when he cares. Even when he doesn't play at his best he is a threat to almost anyone. He spent 10 hrs on court in 2 days and still doesn't give and says he will fight against DelPo.
He always plays his best tennis in DC. That's the best thing I like it about him.
Pitty Karlovic didn't make a point at 4:3, 30:15 on Nalbandian's serve. He had forehand volley and missed for eanch. If he did we would probably won that match.
