Wimbledon.com's highlights from the first day of the WTA Aegon International at Devonshire Park and ATP Aegon Open at Nottingham Tennis Centre...

The WTA's Aegon International in Eastbourne and the ATP's Aegon Open Nottingham have long and storied histories stretching back - on and off - to the 1970s. Rolls of honour include tennis legends from Martina Navratilova and Jimmy Connors to Justine Henin and Richard Gasquet.

Yet 2015 marks a fresh start for both events, enabled by the new third week in between Roland Garros and Wimbledon that has dramatically reshaped and extended the grass season. Having been a mixed event for the past six years, Eastbourne has gone back to its WTA-only status - while the men have returned to Nottingham for the first time since 2008. Additionally, both tournaments have expanded 48-player draws - hence the earlier start than usual.

Konta continues where she left off

Britain's No.2, Johanna Konta, is having a fine grass season so far, having impressed with a quarter-final showing in Nottingham before winning a round and taking the first set off eventual Edgbaston finalist Karolina Pliskova. She picked up in Eastbourne exactly where she left off, scoring a 6-3, 6-2 win over world No.34 Zarina Diyas, of Kazakhstan.

British No.3 Naomi Broady also carried her good form over - though sadly just missed out on an impressive scalp, falling to former Wimbledon quarter-finalist Sloane Stephens, of the USA, 6-3, 3-6, 6-7(4) despite battling back from a 2-5 deficit in the deciding set.

Americans move on

It was a good day for Team USA: as well as Stephens, grass-loving Alison Riske made short work of France's Alizé Cornet - the conqueror of the great Serena Williams at last year's Wimbledon - 6-0, 6-3. Meanwhile, big-serving 2014 's-Hertogenbosch champion Coco Vandeweghe recovered from a wayward opening set to dominate Swedish No.1 Johanna Larsson 6-7(3), 6-1, 6-1.

Other winners included France's Caroline Garcia, who won 24 of 28 first serve points en route to a  6-2, 6-2 rout of Italian veteran Roberta Vinci; the 2013 Wimbledon doubles' runner-up, Australia's Casey Dellacqua, who had no problems against Slovakian 20-year-old Anna Karolina Schmiedlova 6-2, 6-4; and Swiss prodigy, 18-year-old Belinda Bencic, who fought off Germany's Mona Barthel 6-4, 7-6(7).

Teenagers triumph in Nottingham

Two of the three youngest players in the ATP Top 100 were in action on Day 1 of the Aegon Open Nottingham - and both justified the growing hype around them. Alexander Zverev, the 6'6" German 18-year-old, trounced Kazakh veteran Mikhail Kukushkin 6-0, 6-2; while 19-year-old Hyeon Chung, of South Korea, scored his first ever main draw grass win over Spain's Albert Ramos Vinolas 6-4, 7-6(6).

Ukrainian giant-killers find their groove

Ukraine's Sergiy Stakhovsky is best known for his shocking, serve-and-volley-propelled upset of Roger Federer in the second round of Wimbedon in 2013. His compatriot Alexandr Dolgopolov, meanwhile, was the man who upended Rafael Nadal in the first round of Queen's last week. Both are known as mercurial talents rather than reliably consistent players, but neither faced many difficulties today in taking out two Americans: Dolgopolov won 6-4, 6-4 over Donald Young, while Stakhovsky found it straightforward against Steve Johnson 6-4, 6-3.
