ZADAR, Croatia — The chair umpire who penalized Serena Williams in the United States Open final was back at work Friday.
Carlos Ramos was assigned to the best-of-five Davis Cup semifinal series between Croatia and the United States.
“I’m just focusing on this tie and working again. That’s all I can say,” Ramos said before the opening singles match between Borna Coric and Steve Johnson, which he did not officiate.
Ramos worked the second singles match between Marin Cilic and Frances Tiafoe, which was completed without incident.
Ramos calmed the raucous crowd on several occasions and checked a ball mark in the clay at one point, but otherwise had no impact on the match, which Cilic won in straight sets to give Croatia a 2-0 lead.
