Jannik Sinner creating a moment of history by adding the Miami Open title to his Indian Wells victory will certainly not have escaped Carlos Alcaraz's notice
Sinner, 24, became the first man to complete what is known as the 'Sunshine Double' - scooping both trophies on the hard courts in California and Florida - without dropping a set. The imperious nature of the Italian's 6-4 6-4 win over Czech 21st seed Jiri Lehecka in a rain-interrupted Miami final was another illustration of how far Sinner and Alcaraz remain ahead of the chasing pack.
It was also a reminder for Alcaraz - not that he needed one - how he must continue to find ways to further improve if he is able to maintain his current status as the leading player on the men's tour. World number two Sinner has now won his past 34 sets at Masters events, enabling him to join Novak Djokovic and Rafael Nadal as the only men to claim three consecutive titles in the tier of tournaments below the Grand Slams.
Securing another triumph in Miami helped Sinner close the gap on Alcaraz, who was beaten in the third round, at the top of the rankings. The gap is down to 1,190 points as the season moves on to the European clay-court swing, where the pair will unquestionably spar again for the biggest prizes given the stratospheric level on which they operate.
