The pecking order in American men’s tennis changed hands this week without a ball being struck, and the player who lost the top spot spent Wednesday afternoon in Montreal beginning the work of winning it back. Taylor Fritz moved past Ben Shelton in the ATP rankings released Monday, taking over as the highest-ranked American man at No. 9 while Shelton slid to No. 10, on the outer edge of a top 10 he has held for most of the past two seasons. Neither man produced the result that caused it. The calendar did.
Shelton won the Canadian Open last year in Toronto, beating Karen Khachanov in the final for his first ATP Masters 1000 title and the 1,000 ranking points that came with it. Those points came off his total this week. Because the tournament sits a week later on the 2026 calendar than it did in 2025, the ranking system stripped last year’s return before this year’s event began, leaving Shelton to defend a title he had, on paper, already surrendered. The same quirk reshuffled the very top of the list, where Alexander Zverev shed the points from his semifinal run there and dropped to No. 3 behind Carlos Alcaraz, who has not played a competitive match since April.
The mechanics are unglamorous but decisive. A player’s ranking is a rolling 52-week total, and points fall away on the anniversary of the week they were earned rather than on the anniversary of the tournament. When an event moves in the schedule, that gap opens, and everyone who did well the previous year absorbs the loss before they get a chance to replace it. The system rewards consistency and punishes players whose best weeks are concentrated in a single stretch. Shelton’s are.
He began the reply on Wednesday, holding off fellow American Jenson Brooksby 6-3, 7-5 in a first meeting between the two at IGA Stadium. Seeded fifth in a draw that placed him in the tournament’s most crowded quarter, Shelton needed 12 games in the second set to shake off a player ranked 74th who had beaten Adam Walton in straight sets a day earlier. The win moves him into the third round and returns 50 points against the 1,000 now missing.
The wider picture for Shelton is more encouraging than the ranking suggests. He arrived in Montreal 27-12 on the season with three titles on three different surfaces, in Dallas, Munich and Stuttgart, a career first that he has nonetheless described as falling short of what he wants from a season measured in Masters 1000 and Grand Slam results. The hard-court swing has started unevenly. All three of his matches at the DC Open went the distance before Alejandro Tabilo beat him in the quarterfinals.
Fritz arrived in Canada in the opposite condition. He beat 19-year-old Rafael Jodar 7-6 (2), 6-4 in Washington on Monday for his first title since June 2025, ending a stretch of finals that had become the defining frustration of his past year. Seeded seventh in Montreal, he opened against Thiago Agustin Tirante on Wednesday afternoon. The two Americans are drawn in opposite halves and could not meet before the final.
What follows matters more than the label. The top 10 carries seeding protection at the majors, and US Open seedings are set by the rankings published shortly before the draw, which means the next three weeks decide whether the American No. 1 is seeded eighth or 14th in New York. The Cincinnati Open main draw begins Aug. 13 with both men entered, and both appear on the US Open entry list for a tournament that opens Aug. 30.
Montreal has also handed both of them an unusually open field. Jannik Sinner and Novak Djokovic withdrew in the week before the tournament, Alcaraz has not played since the wrist injury he sustained in Barcelona, and Zverev is the top seed in a bracket missing three of the four biggest names in the men’s game. Shelton exploited a similarly thin draw a year ago. He does not need to repeat the title to reclaim American No. 1, but he does need most of it.
His US Open history complicates the arithmetic. Shelton reached the semifinals in 2023 and has not gone as far since, losing in the third round in 2024 and retiring from the same round last year with a left shoulder injury that ended his season. The points he is chasing in Montreal are the ones he can least afford to leave behind.
