Saturday’s doubleheader between the Phillies and Nationals at Nationals Park will be moved to Friday due to the potential impact of Hurricane Ian in Washington, D.C., according to sources close to the situation.

Major League Baseball worked on the plans Wednesday but will not announce the new schedule until later on Thursday. The plan calls for single games in the afternoons on Saturday and Sunday with a contingency for another doubleheader Sunday since Saturday looks like a lost day due to weather forecasts. The series will not be relocated, per sources.

If the Phillies and Nationals cannot play all four games this weekend, there is a small window to reschedule. The league installed one off day — Oct. 6 — between the end of the regular season (Oct. 5) and the start of the three-game Wild Card Series (Oct. 7). If the Phillies have yet to clinch a postseason spot, they would return to Washington after three games in Houston to play the Nationals in a makeup contest.
