Marcora - Duckworth

My mind has a very clear choice with a not very high coefficient, but I am very confident in this choice. Vukic is currently in the best form of the year. He won a Challenger tournament in Canada and had a very good performance in the Washington tournament, which shows his excellent form that he should bring to this tournament. His opponent is a clay-court/sand-court player who recently played in Switzerland on this surface. Chile even has a losing streak of 3 defeats in the first rounds on their favorite surface, and these were against significantly lower-ranked players. Overall, everything seems to be in favor of Vukic, as he has 2 wins against Peru and one of them this year in America on hard court. But it can be seen that Vukic purposely lost to get a LL (Lucky Loser) card, even skipping the first round of the main tournament. Generally speaking, Vukic should easily and confidently handle his opponent, whom he also has additional motivation against, as Barrios is in very poor form, making it hard to expect good tennis from him.
