South Africa's Kevin Anderson has jumped 39 spots to 74th in the latest ATP Tour rankings.
This follows his win over 20-year-old American Jenson Brooksby in the Hall of Fame Open final on Sunday.
It was the 35-year-old South African's first title on grass - and his first ATP crown since the Pune event in 2019.
Since undergoing right knee surgery in February 2020, Anderson struggled on the ATP Tour but battled back last week for his seventh career ATP title.
This one is truly special ?? Winning my 7th title at the @halloffameopen means so much, being with my family and in such a historic place for tennis, it’s just an incredible feeling. Thank you @TennisHalloFame for having me and everyone in Newport and beyond for your support. ?? pic.twitter.com/TlFNF5N6li— Kevin Anderson (@KAndersonATP) July 18, 2021
