This is the first time Kenin and Garcia have faced each other.
Maria and Safarova have never played each other before - and nor have Sevastova and Tomljanovic.
Sevastova is the defending champion, having beaten Julia Goerges in last year's final 6-4, 3-6, 6-3.
Garcia was the inaugural champion here, beating Sevastova in the 2016 final.
Stosur and Riske have faced off twice before - but never on grass. Their previous two encounters both went to three sets - in Rome two years ago, when the Australian won 4-6, 7-6(5), 6-1, and in Tokyo the year before that, when she won 4-6, 6-1, 6-3.
