US Open final chair ump Ramos to work US-Croatia Davis Cup

The chair umpire who penalized Serena Williams a game in the U.S. Open final has been assigned to officiate the Davis Cup semifinal matches between the United States and Croatia, The Associated Press has learned.

International Tennis Federation spokeswoman Heather Bowles confirmed to the AP that Carlos Ramos was chosen to work at the best-of-five series between the countries that begins on Friday and concludes on Sunday in Zadar, Croatia.

The U.S. team includes Jack Sock, Sam Querrey, Steve Johnson, Mike Bryan and rookie Frances Tiafoe.

Ramos was in the chair at Flushing Meadows last Saturday when Naomi Osaka won her first Grand Slam title by beating 23-time major champion Williams 6-2, 6-4. That match descended into chaos — with thousands of spectators booing and both players crying during the trophy ceremony — after Williams confronted Ramos about his rulings.

Williams, a 36-year-old American, was fined a total of $17,000 by the U.S. Open's tournament referee the next day for three code violations.
