The 86-year-old Hoffman was sitting in the Royal Box, an area reserved for special guests invited by the All England Club, while Mahomes and his wife, Brittany, were in the stands, according to local media.
The presence of Hoffman — who won an Oscar for his role in “Rain Man” — was perhaps fitting on a day when showers disrupted play at the grass-court Grand Slam tournament both in the morning and afternoon.
The match between Alcaraz and Tiafoe was played under a retractable roof, keeping everyone dry.
Hoffman is no stranger to Wimbledon. In 2012, he was in Serena Williams’ player box to watch the American’s fourth-round match.
Mahomes, the Kansas City Chiefs quarterback who won his third Super Bowl title this year, had also attended a Morgan Wallen concert in Hyde Park in central London on Thursday.
