## National Representation

At the 2025 Davis Cup qualifiers stage, Bergs struck his rival Cristian Garín (Chile) with his shoulder on his eye while celebrating a point, knocking him down. According to the Chilean team doctor, this caused him "swelling, vision difficulties, nausea, and a severe headache". Bergs was not defaulted, but given a warning for unsportsmanlike conduct. As Garín was unfit to continue playing, and after a quick and controversial assesment by the neutral doctor (a Belgian doctor), umpire Ramos gave him three consecutive time violations, thus ending the match. After the match, the Chile Tennis Federation officially requested to the International Tennis Federation a reversal of the match result, a rescheduling of the decisive fifth match to a later date and an automatic wildcard entry into the Davis Cup Finals, as well as an internal revision of umpire Ramos actions and decisions.
