The Washington Open final between world number three Jessica Pegula and rising star Alexandra Eala will not be decided until Monday after thunderstorms forced play to be suspended on Sunday. Pegula held a one-set lead when the match was interrupted. Eala reached the final by defeating former world number one Naomi Osaka, second seed Elina Svitolina, and defending champion Leylah Fernandez. The WTA final was originally scheduled to finish on Sunday, but rain in the Washington area halted play. Organizers said the match would resume Monday. No further details about the resumption time were given. Eala, a young player from the Philippines, has been the surprise of the tournament, knocking out three higher-ranked opponents on her way to the championship match. Pegula, the top-ranked player in the field, is seeking another title in the U.S. capital. The winner will take home the winner's trophy and ranking points, though those specifics were not announced. Fans will have to wait an extra day to see who lifts the title.
