Grigor Dimitrov's Vienna run ended at the hands of Flavio Cobolli after a hard-fought match of more than two hours, with the Italian moving on to an all-Italian meeting. Earlier in the week, Grigor drew attention sharing a practice court with Carlos Alcaraz.
Cobolli got the better of Grigor in Vienna after a long, tight battle that lasted 2h15.
The win sent Cobolli through to face a fellow Italian in the next round.
Before the event, Grigor practised with Alcaraz in front of a big crowd of fans.
