On Center Court, the Spaniard prevailed 7-6 (7-3) 7-5 6-2 to start the match.
Alcaraz, who won the French Open last month, is aiming to win two major championships in a row.
The 21-year-old remarked, “Stepping on this court, it is the most beautiful court I have played on.” “I still get anxious before performances here.
“I practised for 45 minutes on Thursday and it was the first time I was nervous on practice because I was playing on this court.”
On his maiden appearance in a Grand Slam main draw, Lajal, 21, fought valiantly.
To be honest, I was a little taken aback because I haven’t seen him practice or play much,” Alcaraz continued.
He can advance to a very high level. He is exactly my age, so we will definitely see each other more frequently.
After Alcaraz defeated Austria’s Sebastian Ofner in a thrilling five-set match, the Australian will now play Aleksandar Vukic in the second round.
In the meantime, first seed Jannik Sinner overcame German Yannick Hanfmann in a match that was played partially inside on Court One, winning 6-3, 6-4, 3-6, 6-3.
Hanfmann made things tough for the top seed, but Sinner—the January Australian Open winner—overcame it in three hours.
