Basel: Novak Djokovic made his return after missing six weeks with a back injury and defeated Xavier Malisse 6-2, 4-6, 7-5 in the first round of the Swiss Indoors on Tuesday.
The top-ranked Serb overcame some difficult moments before improving his record this season to 65-3.
Djokovic arrived on the court for the first time since September 18 wearing a fright mask resembling rock star Alice Cooper the night after Halloween. Dressed all in black, Djokovic broke his Belgian opponent`s first service game.
However, Malisse rallied against the US Open champion in the second set and broke in the ninth game.
Djokovic then broke to a lead in the decider, and Malisse required a medical time-out one game later after colliding with the umpire`s chair when racing to retrieve a drop shot.
However, Djokovic failed to serve out the match at 5-3 and wasted a match point chance in the next game.
The Serb then quickly closed out the last two games to complete a 2-hour, 13-minute win.
In Djokovic`s previous match, he retired in a Davis Cup singles match against Juan Martin del Potro of Argentina.
Earlier, fifth-seeded Mardy Fish retired against fellow American James Blake after just one game because of a hamstring injury.
Fish held serve in the opening game and lost the first point of the next game when he decided the pain in his left leg was too much to continue.
Fish is hoping to qualify for the season-ending ATP World Tour Finals for the first time. He stands in the eighth and final qualifying spot for the tournament starting in London on November 20.
Although Fish cannot be overtaken this week, the last qualifying tournament is next week in Paris.
Tomas Berdych of the Czech Republic, sixth in the ATP points race, also missed an opportunity to improve his chances for a spot in London. The fourth-seeded Berdych was ousted by wild-card entry Kei Nishikori of Japan, who won 3-6, 6-3, 6-2.
After third-seeded Roger Federer`s victory on Monday, Switzerland had two more first-round wins.
Michael Lammer, ranked No. 327, beat 37th-ranked Mikhail Youzhny of Russia, 6-4, 6-3 for his first tour win this year.
Swiss No. 2 Stanislas Wawrinka beat Ivan Dodig of Croatia 6-4, 6-4.
Jarkko Nieminen of Finland fought back to beat Thomaz Bellucci of Brazil, 6-7 (5), 6-4, 6-3; Italy`s Andreas Seppi edged Gilles Muller of Luxembourg 7-6 (4), 6-7 (5), 6-2; and Ivan Ljubicic of Croatia beat Frenchman Michael Llodra 7-5, 6-4.
