Carlos Alcaraz and Jannik Sinner have claimed every major title up for grabs so far in 2026.

Alcaraz captured the Australian Open earlier this year to complete his Career Grand Slam, while Sinner has strung together three straight ATP Masters 1000 titles.

The ‘new two’ are a cut above the rest of the ATP Tour right now, and it doesn’t look like that’s going to change anytime soon.

Sinner and Alcaraz, with four and seven Grand Slams each, have already moved past several legends on the all-time list.

They both appear to be tracking toward the grand totals of Roger Federer (20), Rafael Nadal (22), and Novak Djokovic (24) – something Juan Martin Del Potro recently said is within reach.

Del Potro shares thoughts on Alcaraz and Sinner

Speaking to Tennis 365, Del Potro said: “Of course, Carlitos and Jannik are playing magnificent tennis. They are so good, they are playing well on all surfaces, which is very important.

“But I can’t compare them with the Big Three. The other guys, for me, are very special.

“I played my whole career with them. I know how good they are, how difficult it was to achieve everything that they have done for tennis.

“I also know that Carlitos and Jannik have a big opportunity to get closer to them, because tennis now is open, and they are playing much better than the rest.

“So in my point of view, they have big chances to keep winning the big tournaments.”

Carlos Alcaraz is best placed to break Novak Djokovic’s record Grand Slam tally
