Martina Trevisan defeated Elvina Kalieva 6–1, 6–0 in the first round of the WTA 250 Hamburg tournament on clay on 23 July 2023, confirming her status as the pre-match favourite with a dominant performance. The Italian's comprehensive victory, achieved without dropping a set across two decisive frames, underlined her superiority on the surface and suggested strong form heading into the tournament's latter stages. Kalieva, the unseeded underdog, offered minimal resistance and was unable to establish any competitive foothold in either set. Trevisan's clinical display on Hamburg's clay courts reinforced her credentials as a genuine contender for the title.
