The Russian was notoriously blanked 6-0, 6-0 in Monte Carlo last month. On his way to an early exit from that ATP Masters 1000 event, the former world No. 1 drew ire and received a fine for smashing his racket seven times in a contest that lasted all of 49 minutes. But on Friday, against the current world No. 1, Medvedev found himself playing much longer in Rome, on the very surface thats caused him so much trouble over the years. The 30-year-old Medvedev, seeded seventh in the Italian Open, gave top-seeded Italian Jannik Sinner everything he could handle in the semifinals.Medvedev forced a third set, threatening Sinners 32-match win streak in Masters 1000 events a record-breaking mark he set on Thursday, surpassing Serbian great Novak Djokovic and, by extension, jeopardizing Sinners similarly trail-blazing streak of five consecutive Masters 1000 titles.Play 2026 Soccer Pick 'Em with FOX One and make your picks for the world's biggest soccer tournamentUltimately, Sinner escaped unscathed in a match that saw him physically taxed, bent over and taking a medical timeout in the third set. After all of that, play was suspended due to rain in the seventh game of that fateful set. Following a postponement, Sinner, already up 4-2, finished off Medvedev on Saturday after 15 minutes, advancing to the final, thanks to a 6-2, 5-7, 6-4 triumph.Sinner throwing upthis doesnt look good That cameramans reaction though pic.twitter.com/MUQ9Ie0LOD SK (@Djoko_UTD) May 15, 2026Sinner is now one win away from becoming the first Italian to claim the Italian Open since Adriano Panatta accomplished the feat in 1976.
