Alcaraz clinched his sixth major title<\/a> at the US Open<\/a>, but has yet to hoist the Australian Open trophy, which he will have the chance to do next January. <\/p>\n Predicting the first to collect all four on the \u2018Nothing Major\u2019 podcast, former world number eight John Isner<\/a> said: \u201cI\u2019m going to say Alcaraz, just because he has the first shot at it\u2014winning the Australian Open.<\/p>\n \u201cI think just by virtue of that being the next major\u2026 It\u2019s a weird one that he hasn\u2019t done that well at that tournament.<\/p>\n \u201cZverev has gotten him, Djokovic has gotten him there in recent years, so he should be fine.<\/p>\n \u201cIt is a weird one that he hasn\u2019t done it with that level that we saw at the US Open. If he brings that, no one\u2019s beating him, as we know.\u201d<\/p>\n Former American player Sam Querrey added: \u201cI\u2019m agreeing with you. I think Alcaraz has a better shot.<\/p>\n \u201cHim winning on the hard courts feels more feasible than Jannik winning on the clay. I don\u2019t think Jannik\u2019s dominant on the clay.<\/p>\n \u201cHe could have won it this year, but it just feels like, you know, maybe Jannik comes up against Musetti, and then, you know, Casper, and then Alcaraz\u2014it\u2019s a little tougher.<\/p>\n \u201cI\u2019d give the slight edge to Carlos on that one.\u201d<\/p>\n Every men\u2019s player in the Open Era to complete the Career Grand Slam<\/p>\n Only five men in the Open Era have claimed all four Grand Slam titles; the first to do so was Rod Laver in 1969. <\/p>\n It was not until 1999 that Andre Agassi<\/a> followed suit, when the American won his first and only Roland Garros championship. <\/p>\n Both Roger Federer<\/a> and Rafael Nadal<\/a> completed the Career Grand Slam in 2009 and 2010 respectively, with the Swiss star coming out on top at the French Open, and the Spaniard clinching a maiden US Open crown.<\/p>\n![\"Carlos](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/09\/GettyImages-2234264764-1-1024x683.jpg\")
