Troubled Novak Djokovic made a strong start to his Wimbledon preparations with a 6-2, 6-1 demolition of Australian qualifier John Millman at Queen's Club on Tuesday, while Andy Murray prepared to return to action after almost a year on the sidelines.
Djokovic is a lowly 22nd in the ATP rankings after an embarrassing French Open quarterfinal defeat against Italian journeyman Marco Cecchinato extended his wretched run in 2018.
The 31-year-old Serb, hampered by an elbow injury last year, has failed to reach the semifinals in any of his last five Grand Slam appearances.
Djokovic hasn't earned a major title since competing his career Grand Slam by winning the 2016 French Open.
Dogged by rumours that he no longer has the motivation to return to the top, the 12-time Grand Slam winner decided to start his bid for a fourth Wimbledon crown by accepting a Queen's wild card.
With Wimbledon starting on July 2, Djokovic was desperate to improve his lacklustre 14-8 record in 2018.
And, in his first appearance at Queen's since 2010, Djokovic was quickly in the groove on grass as he romped to a first round win in 65 minutes.
Breaks in the fifth and seventh games sealed a one-sided first set.
Barely tested by the world number 63, Djokovic broke twice in the first five games of the second set to see off Millman with ease.
A sterner test lies in wait for Djokovic in the second round against 2017 ATP Finals champion Grigor Dimitrov.
World number five Dimitrov beat Bosnia's Damir Dzumhur 6-3, 6-7 (4/7), 6-3 in his opening match as the Bulgarian bids to win Queen's for the second time.
Later on Tuesday, former world number one Murray will finally set onto court for a competitive match for the first time since his Wimbledon quarterfinal defeat against Sam Querrey 342 days ago.
