YOKOHAMA (Reuters) - Naomi Osaka said on Thursday Serena Williams's row with the umpire during the U.S. Open final had not altered her feelings about winning a Grand Slam, largely because she had no idea how she was supposed to react.

The Japanese player's breakthrough triumph in New York was overshadowed by an explosive row between her opponent Williams and umpire Carlos Ramos which resulted in the 23-times Grand Slam champion being docked a game and fined $17,000.
