On the men\u2019s side, former champion Daniil Medvedev crashed out in his opening match<\/a> against Adam Walton, as the Russian\u2019s poor form continues. <\/p>\n Carlos Alcaraz<\/a> and Jannik Sinner<\/a> remain the favourites to go all the way at the ATP<\/a> event, but one teenage star, who picked up a hard-court Masters title earlier in 2025, may be going under the radar. <\/p>\n With his triumph over American home hope Ethan Quinn in the first round, 19-year-old Jakub Mensik<\/a> now ranks seventh all-time for most Masters 1000 wins as a teenager.<\/p>\n He has 21 wins at the level, more than the likes of Pete Sampras<\/a> and Lleyton Hewitt, and is tied with three-time Grand Slam champion Andy Murray<\/a>.<\/p>\n Should Mensik go all the way in Cincinnati, he can add five more wins to his tally, which would result in him surpassing Andy Roddick<\/a> as fourth on the list. <\/p>\n As the Czech star will turn 20 on the first of September, he will be unable to catch Andrei Medvedev in third place.<\/p>\n Jakub Mensik\u2019s results at ATP Masters 1000 events this year<\/p>\n Mensik kicked off his Masters series at the Indian Wells Open in March, where he reached the second round. <\/p>\n In the second leg of the \u2018sunshine double\u2019, he announced himself to the tennis world, earning victories over top ten players Jack Draper<\/a> and Taylor Fritz<\/a> to advance to the Miami Open final. <\/p>\n Masters 1000ResultIndian Wells OpenSecond RoundMiami OpenChampionMonte-Carlo MastersAbsentMadrid OpenQuarterfinalsItalian OpenFourth RoundCanadian OpenThird RoundJakub Mensik\u2019s results at ATP Masters 1000 events in 2025<\/p>\n![\"A](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/08\/GettyImages-2229308036-1024x683.jpg\")
