Oh c'mon, if he plays even nearly as well as he did today he will take it.
But there's very little reason to think he will, though. This is Frank Dancevic we're talking about. He's well known for those flashes of great play in a inconsistent career. You certainly wouldn't want to put the entire tie on him, he could (and likely would) fail under the pressure of the moment as he has for much of his career.
No, the tie will most likely still comes down to Milos getting done what he should get done. He'll need to do better than today to win, but if he serves well on these courts, it's tough to see Granollers beating him. Just doesn't have the same weapons.
Would be nice to get a surprise doubles win so neither of the matches matter, though.
