The new tennis rankings showed predictable results but there were some upset as well. After winning the Memphis Open, Ryan Harrison climbed to the top 50 for the first time in five years.

He is the biggest mover in the new rankings and he is seriously attracting a buzz for his comeback.

Harrison was declared early in his career to be the new American tennis star after Andy Roddick. The player was under a lot of pressure to impress but he never quite lived up to the expectations. The 24-year old star – despite the number of years in the spotlight – shocked the tennis world when he won his first ATP title. He did it in style, as he did not drop a single set throughout.

Roddick quickly took to his Twitter profile to congratulate the player for his victory. Harrison is the first American to win the Memphis Open since Roddick back in 2011.

David Goffin, 26, is another player that was favoured by the new ranking. He is the first Belgium international to break into the top ten of the ATP rankings, with his display in Sofia and Rotterdam giving credence. He has been decent in the ATP circuit, hence his rise. He was set to get his first title in three years but he was denied by Grigor Dimitrov and Jo Wilfried Tsonga.

Tsonga, 31, won his 13th career title when he saw off a challenge from Goffin at the Rotterdam Open – his first ATP title since 2015. He only returned from a knee injury last year but the victory sees him move to 11th place in the new rankings. His win in Netherlands means he had to wait six years for it after his meeting with Robin Soderling in the 2011 final.

On the flip side Dominic Thiem has suffered in the rankings, with the schedule not favouring him. The 23-year old is hardworking but he would have to better manage his time.

David Ferrer is another tennis star that is not doing well in the new rankings. Ferrer has been consistent but the 34-year old is starting to wear down.
