Will Arthur Fils be in the ATP Top 10 on August 31?

Why: 1) Wikipedia states ATP rankings are updated weekly on Mondays (UTC) → 31 Aug 2026 (a Monday) is a scheduled rankings date. Source: en.wikipedia.org/wiki/Current_tennis_rankings. 2) The ATP official rankings page lists 2026.08.31 as a selectable rankings date → there is an ATP rankings list with the ‘as of’ date 2026-08-31 to check against. Source: atptour.com/en/rankings/singles. 3) ATP’s own “Movers of the Week” article specifies changes “as of Monday 31 August 2026” → confirms that the 31 Aug 2026 rankings were published that day. Source: atptour.com/en/news/buse-pif-atp-rankings-31-august-2026. 4) On 31 Aug 2026, Tennis.com’s US Open match page shows Arthur Fils with Singles Ranking 11 → his ATP singles ranking number that day was 11, i.e., outside 1–10. Source: tennis.com/tournaments/us-open/matches/s-tsitsipas-vs-a-fils-2026-08-31. 5) Independent lists corroborate the top 10 on/for that ranking date do not include Fils: ESPN’s ATP rankings page lists Taylor Fritz 10th and Arthur Fils 11th; Olympics.com’s 31 Aug 2026 update likewise names Ben Shelton 9th and Taylor Fritz 10th, implicitly excluding Fils from the top 10. Sources: espn.com/tennis/rankings; olympics.com/en/news/atp-singles-world-rankings-complete-tennis-list-jannik-sinner-carlos-alcaraz-novak-djokovic. Conclusion: Arthur Fils was ranked 11 on the ATP rankings ‘as of’ 2026-08-31, so he was not ranked 1–10.
