Argentinian tennis player Camilo Ugo Carabelli (48th) defeated Bolivian Hugo Dellien (149th) to advance to the semi-finals of the Challenger in Rosario. According to the Argentine News Agency, the defending champion of the tournament, held at the Rosario Jockey Club, secured his spot with a 6-4, 6-2 victory. Thus, Ugo Carabelli will face the fourth-seeded Argentine Juan Manuel Cerúndolo (85th) for a place in the final. With some errors and physically weakened, and also having to continue a suspended match against Manuel La Serna, Dellien ceased to be a threat for the 'Brujo'. Camilo Ugo Carabelli was the one who set the pace of the points and decided their outcome: either he won them with winners after making his opponent run, or he lost them by taking too many risks. Accelerating with the parallel backhand and dominating with his forehand and drop shots, Ugo Carabelli managed to break in the first and seventh games, and then closed out the match with a parallel backhand. Valerio Aboian could not continue his surprising run and fell in the quarter-finals. The Argentinian tennis player Valerio Aboian (526th) could not continue his winning streak and lost to the Taiwanese player Chun Hsin Tseng (122nd). Aboian, who had entered the main draw as a lucky loser and had achieved two wins to reach the quarter-finals, lost 6-2, 6-1. Nevertheless, it was a great week for him: he gained 19 points and climbed 60 places, reaching the 466th spot in the live ATP ranking.
