Errors started to appear, wide balls, and frustration grew. On the other hand, Dellien began to grow in confidence, with some effective passing shots and lobs, and started to play on his opponent's mistakes. Despite having good moments, he lacked effectiveness at crucial times, wasting eight set points. When the tie-break arrived, with three set points against him, the Argentine won the last five points consecutively and did not forgive, sealing the match on his only match point with a serve down the line that his opponent returned long. Argentine tennis player Francisco Cerúndolo (19th) defeated Bolivian Hugo Dellien (167th) in a very changeable match played at the Guillermo Vilas stadium in Buenos Aires, for the Argentina Open round of 16. According to the Argentine News Agency, the current tournament finalist won the match 6-0 and 7-6 (6). With a victory that went from comfortable to hard-fought, Cerúndolo advanced to the third round of the tournament, where he will face Czech player Vit Kopriva (95th), who has had a good week so far. The first set showed the huge ranking differences between the two players. Cerúndolo played a perfect set, with only two unforced errors, and was vastly superior, breaking Dellien's serve three times. Having lost only one of the 13 points he played on his serve, Francisco Cerúndolo took the first set 6-0 in just 18 minutes of play, in front of the incredulous crowd at the Guillermo Vilas stadium. However, as is often the case, the Argentine began to get into his own head.
