The 16-year-old son of Australia's former world No.1, who had gone through qualifying to make the event at Roland Garros, proved a handful on Sunday for Italian Pierluigi Basile, two years his senior and higher-placed in the world junior standings, before succumbing 7-6 (7-4) 5-7 6-3.
Hewitt lost the tightest of opening sets on a breaker and looked practically down and out as Basile served for the match at 5-3 in the second set and earned a match point at 5-4, but the Sydney youngster fought tigerishly to turn it around and take the match into a decider.
The Italian had the superior firepower but Hewitt wouldn't lie down, revving up the the galleries packed round the tight court No.4 with the sort of crowd-rousing exhortations taken straight from his father's book.
Ultimately, he lost in two hours 10 minutes, unable to reach the second round as he had done at the junior event in January at the Australian Open, where he also lost in the first round in the qualifiers for the senior event.
On Monday, 16-year-old Emerson Jones, the world's No.2 female junior, kicks off her campaign as top seed in the girls' event against US qualifier Capucine Jauffret, while the other Australian in the boys' tournament Ty Host will face US sixth seed Benjamin Willwerth.
Hewitt wasn't the only son of a famous player to feature in Sunday's program, with fifth seed Jagger Leach, whose mother is American former triple grand slam winner Lindsay Davenport, beating Kazakh Zangar Nurlanuly 6-1 1-6 6-0.
