There are some very notable movers on the ATP rankings this week, including American Learner Tien breaking into the Top 20.
The 20-year-old Californian rises from No. 21 to No. 20 following his run to the fourth round of Rome, which wasn’t just his best career result at a Masters 1000 event on clay, it was actually the first time in his career that he’s won back-to-back matches on the surface.
As of now, his best results have all come on hard courts, including his first ATP title (Metz last year), another ATP final (Beijing last year), his best Grand Slam result (the quarterfinals of the Australian Open earlier this year) and his best Masters 1000 result (the quarterfinals of Indian Wells earlier this year).
But Tien is now finding his groove on other surfaces, without much to defend the rest of the clay season, or even the grass season.
He’s currently the No. 3-ranked American man, after Top 10 players Ben Shelton (No. 6) and Taylor Fritz (No. 8). Frances Tiafoe (No. 21) and Tommy Paul (No. 26) round out the U.S. men’s Top 5.
