If I am not wrong, he will lose 20 points.
15 of the 2nd round in Viña and 5 of the 1st round in Buenos Aires.
The 10 points from Costa Do Sauipe, he will defend them in Memphis.
He will lose 9 points from Viña and 5 from Costa. And in that Memphis week he will need to win his first round to add a couple of points (10 points with a first round win, 35 with a QF spot).
