Tsitsipas's US Open Controversies and On-Court Outbursts
Stefanos Tsitsipas expressed anger and disapproval towards Daniel Altmaier's use of the underarm serve during their US Open match, which ended in a five-set defeat for Tsitsipas. The Greek player criticized Altmaier for targeting his body and was involved in tense exchanges, including a warning for coaching during the match.
