Diego Schwartzman defeated Oleksii Krutykh 6–4, 6–7, 6–3, 7–6 in the first round of the Australian Open on hard court on 17 January 2023, confirming his status as the pre-match favourite with odds of 1.58 to Krutykh's 2.52. The Argentine weathered a competitive second set that went to a tie-break before reasserting control in the third, then edging a fourth-set tie-break to secure passage. The result reflects Schwartzman's higher seeding and ranking advantage against an opponent ranked outside the top 100, though Krutykh's competitive showing in two of the four sets suggested occasional resistance. Schwartzman advances to face a second-round opponent as he aims to build momentum in Melbourne.
