Marin Cilic made the biggest move among top players in this week's ATP rankings, rising from No. 37 to No. 29 after another strong tournament.
The 25-year-old made the final of the ABN AMRO World Tennis Tournament, one week after winning the Zagreb Indoors. Cilic, a top-20 mainstay who peaked at No. 9 four years ago, slipped as low as No. 47 last year after serving a four-month doping ban.
