In April, the world’s best male player, the Italian Jannik Sinner, will swap the blue hues of Rod Laver Arena for a more confronting court; his doping appeal case against the International Tennis Integrity Agency, the World Anti-Doping Agency and the International Tennis Federation, is listed for two days in the Court of Arbitration for Sport.

Everything that Jannik Sinner means to the summit of men's tennis could be temporarily wiped away in just a few months.

Tennis fans are calling out the great "shame" of Jannik Sinner's march into the Australian Open semi-finals at the expense of Alex de Minaur - given anything he achieves in Melbourne will be clouded by a possible suspension.

Sinner's remarkable on-court ability to block out any distraction from his mission has been on full display as he seeks to defend his Melbourne title.

Since Hewitt won his last major title, only two Australians have even reached grand slam finals - Hewitt at the Australian Open (2005) and Nick Kyrgios at Wimbledon (2022). At 19 years old, Kyrgios was anointed Australia's next grand slam winner when he beat Rafael Nadal and reached the Wimbledon quarter-finals in 2014.
