Debuting at the age of 20 against Australia in August 1992, his rise to his best bowler in the world status was initiated with his extraordinary spin-bowling prowess. His unique, almost freakish action, coupled with an angular run-up, set him apart from conventional spinners. In his first Test, he claimed the wicket of Craig McDermott, with his special powers evident when Tom Moody's leg-stump was dislodged by a delivery pitching well outside the off-stump. Muralitharan's close bond with captain Arjuna Ranatunga during Sri Lanka's back-to-back Test victories solidified his position as the team's primary wicket-taker, ushering in a new era in Sri Lankan Cricketer history.

Muralitharan's cricketing journey continued to ascend, marked by notable achievements on foreign soil. In 1993, he secured his first five-wicket haul in Tests against South Africa, including notable dismissals like Kepler Wessels and Hansie Cronje. Despite Sri Lanka's struggles against India in 1993–94, Muralitharan stood out with 12 wickets, showcasing perseverance against formidable opponents. His prowess as a match-winner on diverse surfaces was evident in New Zealand in 1995, where the Sri Lankan Cricketer played a pivotal role in their historic series victory. By overcoming doubts about his ability to trouble subcontinental batsmen, Muralitharan silenced critics and established himself as his country's leading wicket-taker, setting the stage for his title as the best bowler in the world.
