The Biggest Movers in the ATP Rankings this week reflect the seismic impact of the Miami Open, the second ATP Masters 1000 of the 2026 Sunshine Swing.
Champion Jannik Sinner completed the coveted Sunshine Double, becoming the first man since Roger Federer in 2017 to win both Indian Wells and Miami in the same season. His title is his 13th Big Title, and he now sits within just two Big Titles of rival Carlos Alcaraz in an intensifying race at the top of the men’s game.
Lehecka’s maiden Masters 1000 final appearance was the breakout story of the fortnight, while wildcard Martín Landaluce’s improbable quarterfinal run captured the imagination of the entire tennis world. Meanwhile, defending champion Jakub Mensik and semi-finalist Taylor Fritz found themselves on the wrong side of the ledger, shedding points they could not afford to lose.
Biggest Movers in the ATP Rankings This Week
Moving Up
Jannik Sinner: (to #2)
Sinner reached the final with a 6-3 7-6 win over Alexander Zverev on Friday night, then closed out the title in straight sets against Lehecka on Sunday. With the title secured, he now trails world #1 Carlos Alcaraz by just 1,190 points in the live rankings — a gap that looked far wider at the start of the swing. The Italian has given himself a genuine platform to reclaim the top spot at Monte Carlo.
Jiri Lehecka: +8 (to #14)
Lehecka reached his maiden Masters 1000 final with a composed straight-sets victory over Landaluce, 7-6 7-5. He became the first player to reach a Masters 1000 final without his serve being broken since Novak Djokovic at the 2018 Shanghai Masters — a remarkable feat across five matches. His wins over Tommy Paul and Arthur Fils were particularly telling. The final against Sinner was a step too far, but the Czech’s consistency throughout the draw confirmed he belongs in the conversation among the sport’s elite.
Arthur Fils: +3 (to #28)
Arthur Fils dramatically saved four match points to escape Tommy Paul at the Miami Open, with the 21-year-old winning 6-7 7-6 7-6 to reach his maiden ATP Masters 1000 semi-final. His run came to an end against Lehecka, but the week as a whole delivered both a ranking boost and a statement of intent. Since returning from a stress fracture, Fils has posted 13 wins in 17 matches, five of which have come against top-30 opponents. The Frenchman’s mentality under pressure is beginning to look like a genuine weapon.
Terence Atmane: +9 (to #44)
Terence Atmane produced a quietly excellent week in South Florida, reaching the fourth round with a notable win over seventh seed Felix Auger-Aliassime the highlight for the Frenchman. His aggressive, first-strike game is beginning to translate consistently at this level, and a new career-high of #44 is the reward.
Martín Landaluce: +46 (to #105)
The story of the tournament. The 20-year-old Spanish qualifier, ranked 151st, reached the quarter-finals, becoming the lowest-ranked player to do so at Miami since #185 Jim Grabb in 1994. He defeated seeds Luciano Darderi, Karen Khachanov, and Sebastian Korda on his way to the last eight and departs the tournament just outside the top 100 at a new career-high ranking. A week that will not be forgotten quickly.
Moving Down
Jakub Mensik: -13 (to #26)
The defending champion paid the steepest price. Menšík shed 905 ranking points following a third-round exit against Frances Tiafoe and is projected to fall 12 places in the live ATP rankings. The brutal mathematics of title defence at the Masters 1000 level do not account for context. The Czech drops sharply despite having entered the week with every reason for confidence.
Brandon Nakashima: -3 (to #33)
Nakashima failed to replicate last year’s deep run in Miami. A quiet exit from a player who will want to put this week behind him quickly as the clay season begins.
Best Matches of the Fortnight
Several standout contests delivered genuine drama across the two weeks in South Florida:
QF — Arthur Fils vs Tommy Paul: In one of the matches of the season, Fils came back from 2-6 down in the deciding tiebreak, tallying six consecutive points to advance in a two-hour, 47-minute clash in which neither player was broken throughout. Paul had been the more aggressive player for long stretches, answering Fils’ heavy topspin with his own artillery, but Fils’ resilience at the most critical moments proved decisive. A match that will be referenced for years.
QF — Jiri Lehecka vs Martín Landaluce: Lehecka ended Landaluce’s remarkable run with a composed performance against an opponent with nothing to lose who had produced many highlight-reel shots throughout the tournament.The Czech created ten break point chances to Landaluce’s one and capitalised in the closing stages of both sets. A generational contrast that played out with real quality on both sides.
SF — Jannik Sinner vs Alexander Zverev: Sinner extended his head-to-head winning streak over Zverev to seven with a 6-3 7-6 victory, winning 79% of his first-serve points and landing 15 aces across the match. Zverev competed hard and the second set was tight, but the Italian’s serving and composure under pressure made the outcome feel inevitable from the early stages.
Final — Jannik Sinner vs Jiri Lehecka: Lehecka entered the final having not had his serve broken all tournament, but Sinner closed out the match 6-4 6-4 in a performance that underlined why he has been the most complete player on hard courtd so far this season. Lehecka competed diligently but Sinner’s level on the day allowed no foothold.
Miami 2026 delivered its usual blend of brilliance and upheaval. Sinner’s Sunshine Double stands as the defining story of the fortnight; historically significant, technically immaculate, and psychologically pointed at a rival in Alcaraz who exited early and watched from home. Lehecka’s emergence as a genuine top-15 force is the secondary headline, while Landaluce produced the kind of week that the sport’s occasional wildcards live for. The circuit now turns its attention to clay, where the rankings will be reshuffled all over again.
