Taylor Fritz and Tommy Paul will need to wait until Monday to play for the Delray Beach Open title. The singles and doubles finals at the ATP 250 were delayed by a day due to rain.
The doubles final between top seeds Santiago Gonzalez/Neal Skupski and third seeds Julian Cash/Robert Galloway will begin at 10 a.m. The singles championship match will start not before 12:30 p.m.
Fritz and Paul, friends since the juniors, have split their four Lexus ATP Head2Head meetings. They most recently met in last year's Acapulco semi-finals, which Paul won in a final-set tie-break.
Fritz will try to earn his first ATP Tour title of the season and become the second player in tournament history to successfully defend the title, joining Jason Stoltenberg, who triumphed in 1996 and 1997.
Paul, who lifted the trophy last week in Dallas, can become the first American to earn tour-level titles in consecutive weeks since John Isner emerged victorious in Newport and Atlanta in 2017. He is on a seven-match winning streak, tied for the best of his career.
