Hubert Hurkacz defeated Alexander Zverev 6-3, 6-4 in the round-robin stage of the United Cup on hard court on 5 January 2026. The Polish player controlled both sets with consistent tennis, breaking Zverev's serve twice in the opening set and maintaining that momentum through the second to secure a straightforward victory. Hurkacz's performance underlined his capability on hard courts early in the season, whilst Zverev's loss marked a disappointing start to his campaign in the team event. The result gives Hurkacz valuable momentum heading into the remainder of the tournament's group stage.
