KITZBUHEL, Austria. Yannick Hanfmann stunned former world No. 3 Dominic Thiem 6-4, 3-6, 6-4 to reach the semi-finals at the Generali Open on Thursday.
Tim was down 5-4 in the third set when play was suspended due to rain and the 2020 US Open champion was unable to hold his serve when play resumed.
Thiem, 28, returned in March from a long-term wrist injury and has reached at least the quarter-finals in his last three tournaments.
This is just the fourth ATP semi-final for Hanfmann, who finished 140th. The 30-year-old German will next play either Dusan Lajovic or Filip Misolic, whose quarter-final match has been suspended.
Third-placed Spaniard Roberto Bautista Agut beat Jiri Lehecca 4–6, 7–5, 7–5.
He will next play compatriot and fifth seed Albert Ramos-Vinolas, who eliminated another Spaniard, seventh seed Pedro Martínez, 6-4, 6-2.
