The 19-year-old found a number of stunning angles in front of the packed crowd on Court des Princes and played with intensity to overwhelm Berrettini, who defeated Daniil Medvedev<\/a> 6-0, 6-0 in the second round.<\/p>\n “It is super special. I was looking for this result for a long time,” Fonseca said. “Of course I want more. I am very confident and focused. I was very happy with the way I fought today. From the beginning, putting a lot of pressure. Playing huge return games and very good serve games. I was putting a lot of pressure and that helps you stay more calm during the match.”<\/p>\n Fonseca won 94 per cent of first-serve points in the opening set and did not let a setback at the start of the second deter him. Berrettini was broken at the beginning of the second set but responded immediately when he crushed a forehand pass to level at 2-2, triggering a roar from the former Top 10 star.<\/p>\n However, Fonseca continued to play aggressively and pulled the Italian from corner to corner to regain momentum and triumph after 75 minutes. Fonseca is the first Brazilian Masters 1000 quarter-finalist since Thomaz Bellucci<\/a> in Madrid in 2011, while he is the youngest man to reach this stage in Monte-Carlo since Rafael Nadal<\/a> and Richard Gasquet<\/a> in 2005.<\/p>\n Fonseca, who is making his debut in Monte-Carlo, is up five spots to No. 35 in the PIF ATP Live Rankings after levelling his Lexus ATP Head2Head series with Berrettini at 1-1. The former Next Gen ATP Finals champion will meet third seed Alexander Zverev<\/a> in the last eight.<\/p>\n Zverev downed Zizou Bergs<\/a> 6-2, 7-5 to reach the quarter-finals in the Principality for the first time since 2022. The German failed to serve out the match at 5-4 in the second set, but quickly bounced back to reel off the final two games to triumph.<\/p>\n “[It was] a better match from my side,” Zverev said when asked how it compared to his opening-round win on Wednesday in Monte-Carlo, where he rallied from 2-5 in the deciding set to defeat Cristian Garin<\/a>. “It was still not perfect. Still far from the level I played in the US, but this is my first clay tournament… I am happy with the level today. We move forward.”<\/p>\n The No. 3 player in the PIF ATP Rankings Zverev is chasing his eighth Masters 1000 crown and will now meet Fonseca for the first time. Last month, Fonseca faced Carlos Alcaraz<\/a> and Jannik Sinner<\/a> for the first time in Miami and Indian Wells, respectively, pushing both in narrow defeats.<\/p>\n “I think clay is his best surface,” Zverev said when discussing Fonseca. “He won Buenos Aires and has played well on the surface before. I am excited to play him for the first time. He is a young upcoming talent and I think we will play each other a lot more in the next couple of years.”<\/p>\n![\"\u201cATP\"\/](\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2026\/01\/1768144283_348_atp-no-1-club-banner-article.jpg\")
