Thiem Returns To Career-High, Mover Of The Week

No. 4 (Career-High) Dominic Thiem, +1
In his first three appearances at the Nitto ATP Finals, Dominic Thiem won just one match apiece, and was unable to advance to the semi-finals. But the Austrian star got off to a fast start this year, defeating Roger Federer and Novak Djokovic in back-to-back matches, before defeating defending champion Alexander Zverev in straight sets to make his first championship match at the season finale. The 26-year-old, who also won his first ATP Masters 1000 title this year at the BNP Paribas Open, will finish the season at a career-high year-end World No. 4.

No. 78 (Career-High) Jannik Sinner, +18

The day after the 2018 Nitto ATP Finals, a 17-year-old Jannik Sinner was No. 762 in the ATP Rankings. One year later, the Italian teen is up to a career-high World No. 78. Sinner won his third ATP Challenger Tour title on Sunday — also his third of the season — in Ortisei to become the second-youngest player to capture three Challenger trophies in a season. The only player who accomplished the feat at a younger age than the Next Gen ATP Finals champion is Richard Gasquet, who did it at 17.

No. 95 Ivo Karlovic, +11

Ivo Karlovic reached the final at the Houston ATP Challenger Tour event to climb 11 spots, propelling him into the Top 100, where he is projected to finish the season. This will be the 16th time in 17 years that the Croat has completed a year inside the Top 100. Karlovic finished year-end No. 101 in 2018, which means he was one spot away from accomplishing the feat for 17 consecutive seasons. Karlovic, now 40, first did it when he was 24.
