Nick Kyrgios took just 48 minutes to win his Miami Open second-round match against Dusan Lajovic.

In his first match since Davis Cup nearly two months ago, the 17th-seeded Australian served seven aces and was never in any trouble as he steamrolled his Serbian opponent 6-4 6-1.

Kyrgios has been sidelined in February and March due to an elbow problem but showed no sign of discomfort as he hit 21 winners to set up a third-round showdown with Italian 15th seed Fabio Fognini.
