On the back of their first career WTA titles last week, Americans Madison Keys and Coco Vandeweghe each set new career-high marks in the rankings. Keys, the youngest player in the top 50 since the end of last season, now becomes the youngest player in the top 30. She rises 17 places from No. 47 to No. 30 and passes Venus Williams to become the American No. 3.

Vandeweghe, whose previous ranking was No. 69, qualified to win the International-level event in 's-Hertogenbosch. She upset Garbine Muguruza and Klara Koukalova en route, and rises nearly 20 places to No. 51.

Speaking of breakthroughs, Great Britain's Heather Watson became the first British woman to reach the semifinals in Eastbourne since Jo Durie in 1982, and rises 10 places in the rankings this week. Watson missed much of 2013 due to a bout of mononucleosis, but has made a winning return to the WTA Tour. She upset Flavia Pennetta en route to the semis in Eastbourne, before falling to Keys. Far off of her career-high of No. 39, she rises to No. 60 for her efforts. 

On the men's side, a first-time title-winner also triumphed in 's-Hertogenbosch. Roberto Bautista Agut was forced to rally from a set down in both the semifinal and final, but managed to walk away with the trophy. He rises five spots in the rankings to a new career-high of No. 23. The beaten finalist in Rosmalen, Benjamin Becker, long known for sending Andre Agassi into retirement, moves up 18 places to No. 65. 

American Sam Querrey reached his second semifinal of the year on the grass in Eastbourne, before falling to eventual champion Feliciano Lopez. Querrey, who began the year as the American No. 2, slipped to the No. 6 American in the top 100 prior to his Eastbourne run. With the semifinal result, he moves up 10 places to No. 67 and returns to the No. 2 position behind John Isner.
