Novak Djokovic needed a deciding tie-break to see off young Czech Tomas Machac at the ATP Tour event in Dubai in his first match since the Australian Open.
The Serbian took three weeks off after defying a hamstring problem to win a record-equalling 22nd grand slam title in Melbourne and looked understandably a little rusty in a 6-3 3-6 7-6 (1) win against 130th-ranked Machac.
