An ominous Carlos Alcaraz warned he was getting “better and better” after sweeping into the Australian Open last 16 on Friday. 

The Spanish World No. l wasted little energy in his 100th Grand Slam match — he has won 87 of them, matching Bjorn Borg’s record at the same stage of his career — with a 6-2, 6-4, 6-1 mauling of France’s Corentin Moutet, ranked 37th.
