Amid waving Chinese flags on Court 5 in Roland Garros, Zhang started the match strong, breaking Lajovic four times to sweep the first set.
"I performed well today, I kept my cool at crucial moments and made few unforced errors," said Zhang, reflecting on his victory. Prior to this, he had lost all his previous three Grand Slam first-round matches in five-set battles.
Zhang, aged 27, then broke in the fourth game and held his own serve to surge to a 4-1 lead in the second set, after which Lajovic was unable to continue playing.
