Serena Williams says she has not thought about her controversial defeat against Naomi Osaka in last year's US Open final as she again goes for a record-equalling 24th Grand Slam title.
American Williams, 37, called umpire Carlos Ramos a "thief" and a "liar" as he docked her a game amid extraordinary scenes on Arthur Ashe Stadium.
She meets Canadian Bianca Andreescu, 19, in this year's final on Saturday.
On last year's final, Williams said: "It hasn't really crossed my mind."
Williams is competing in her 10th US Open singles final, 20 years after her maiden victory in New York, while Andreescu is playing in her first Grand Slam final on her main-draw debut at Flushing Meadows.
