LONDON — Novak Djokovic's first appearance at Queen's Club in eight years was successful when he put away Australian qualifier John Millman 6-2, 6-1 on Tuesday.

Djokovic, entered as a wild card, will play second-seeded Grigor Dimitrov in the second round.

Also, Milos Raonic, runner-up to Roger Federer last week in Stuttgart, won his opener when Indian qualifier Yuki Bhambri retired hurt while trailing 6-1, 3-1.

Djokovic's comeback from right elbow surgery in January has been gathering pace after reaching the Rome semifinals and French Open quarterfinals. He leads Dimitrov 6-1 in career matchups.

Dimitrov, the 2014 Queen's champion, struggled past Damir Dzumhur 6-3, 6-7 (4), 6-3. Dimitrov saved six of eight break points.
