Ranking Reaction: Ben Shelton breaks into Top 15 after winning first ATP title in Tokyo

American Ben Shelton continues his incredible rise up the ATP rankings today, moving up four spots from No. 19 to No. 15 after capturing the first ATP title of his career at the ATP 500 event in Tokyo.

The 21-year-old hasn’t even been in the Top 100 for a full year yet—he made his Top 100 debut last November after winning three Challenger titles in three weeks, his Top 50 debut in January after reaching his first major quarterfinal at the Australian Open and his Top 20 debut in September after reaching his first major semifinal at the US Open.

And today, his Top 15 debut.

There are now four Americans in the Top 15 of the ATP rankings: No. 9 Taylor Fritz, No. 12 Tommy Paul, No. 14 Frances Tiafoe and No. 15 Shelton.

A little further down, Nicolas Jarry breaks into the Top 20 for the first time, rising from No. 21 to No. 20. He didn’t play any tournaments this past week but moves up after Lorenzo Musetti dips from No. 20 to No. 22.

Jarry, who’s had a breakthrough year highlighted by two ATP titles, three Top 10 wins and a first Masters 1000 quarterfinal in Shanghai, is the seventh Chilean player to reach the Top 20 in ATP rankings history.

CHILEANS TO REACH TOP 20 ON ATP RANKINGS (since 1975):
~ Marcelo Rios [career-high No. 1 in 1998]
~ Fernando Gonzalez [career-high No. 5 in 2007]
~ Nicolas Massu [career-high No. 9 in 2004]
~ Hans Gildemeister [career-high No. 12 in 1980]
~ Jaime Fillol Sr. [career-high No. 14 in 1974]
~ Cristian Garin [career-high No. 17 in 2021]
~ Nicolas Jarry [career-high No. 20 in 2023]

One of the other names on that list is very familiar to Jarry, too: Jaime Fillol Sr. is his grandfather, even giving him his first tennis racquet and taking him to tournaments like Wimbledon and the US Open as a child.

The biggest jump in the Top 100 belongs to Gael Monfils, who soars 51 spots from No. 140 to No. 89 after capturing the 12th ATP title of his career on the indoor hard courts of Stockholm over the weekend.

Having been ranked in the Top 20 as recently as last summer, Monfils dropped out of the Top 100 during a seven-month foot injury lay-off between August 2022 and March 2023, even falling as low as No. 394 early on in his comeback to the tour as he was working his way back into top form. But he was in vintage form in the Swedish capital last week and is now firmly back in the Top 100, and with barely any ranking points to defend until next summer, how high can the Frenchman go?

The biggest jump in the Top 200 belongs to 20-year-old Japanese breakout star Shintaro Mochizuki, who went into Tokyo without ever having won a tour-level match but made it all the way to the first ATP semifinal of his career at the ATP 500 event, notching his first Top 10 win en route against Fritz. He soars 84 spots from No. 215 to No. 131 today.

And 23-year-old Petros Tsitsipas, the younger brother of Stefanos Tsitsipas, breaks into the Top 100 on the ATP doubles rankings today, rising from No. 110 to No. 81—shattering his previous high of No. 107—after capturing his first ATP doubles title in Antwerp with his big brother.

Meanwhile, there were three WTA 250 events last week, and all three title winners make big moves up the WTA rankings today: Elise Mertens returns to the Top 30, rising from No. 36 to No. 30 after winning in Monastir, Tunisia; Katerina Siniakova returns to the Top 50, jumping from No. 60 to No. 46 after winning in Nanchang, China; and Tamara Korpatsch returns to the Top 100, rising from No. 105 to No. 71—surpassing her previous high of No. 74—after winning in Cluj-Napoca, Romania.

Former Top 20 player Leylah Fernandez also continues her resurgence up the rankings, rising from No. 43 to No. 35 after reaching the semis in Nanchang. Last week she rose from No. 60 to No. 43 after winning in Hong Kong, meaning she’s cut her ranking in almost half in two weeks.
