Stuttgart, Germany, 15 June 2018 | tennis.com.au

Back in singles action for the first time in two months, Nick Kyrgios made a winning start in Stuttgart.

The world No.24 recorded a 6-4 4-6 6-3 victory over German Maximilian Marterer to book a quarterfinal spot at the Mercedes Cup.

Kyrgios, who missed Roland Garros last month with an elbow injury, fired 20 aces in the 87-minute victory. It sets up a quarterfinal showdown with eighth seed Feliciano Lopez of Spain.

Bernard Tomic plays his quarterfinal tonight, taking on Fernando Verdasco. Tomic has won his past five matches against the fourth-seeded Spaniard. Matthew Ebden is also into the final eight, where he’ll play Romanian Marius Copil.
