Looks like he had a very tight match. On to the next challenger. Can some one explain to me how the points in challengers work toward getting into qualis for ATP events. I don't know anything about that system. Also how is Mariano doing in regard to points and his long journey to the ATP. Anyway I'm glad to see him in SF's and a final this season and hope he continues to improve his success.
As any ATP event, Challengers give players points. The points are acumulated. ATP Tour/International Series tournament requires NORMALLY a higher amount of points than challengers. When he accumulates points enough to enter in ATP Tour/IS tourney draw or qualy draw, he'll play the ATP Tour/International Series tourneys.
He can also get in the draw with a WC like he did for the Sevilla Challenger.
