Updated Schedule for rain-hit Washington ATP 500

Update: Shelton and Cobolli began playing at 9.45 p.m.

Editor's Note: The tournament has released an updated schedule for tonight: The Shelton v Cobolli match has been moved to John Harris court, starting not before 9 p.m. Tiafoe and Korda are scheduled not before 9 p.m. on Stadium following the WTA semi.

Saturday night's men's singles semi-finals at the Mubadala Citi DC Open have been delayed by rain and lightning. 

Ben Shelton and 22-year-old Italian Flavio Cobolli are scheduled to open the evening session, followed by an all-American matchup between local hero Frances Tiafoe and Sebastian Korda. It marks the first time since 2001 that three American men have advanced to the Washington semis.

Shelton, Tiafoe and Korda are hoping to snap a 17-year wait for a home champion by becoming the first American to win the D.C. title since Andy Roddick in 2007. Cobolli, who competed in the Next Gen ATP Finals presented by PIF last November, is seeking his first tour-level final.

Before the nighttime men's action can begin on the Washington stadium court, the women's semi-final between Aryna Sabalenka and Marie Bouzkova still needs to be completed. Sabalenka led 4-6, 6-3, 2-1 when lightning suspended play.
