Game 4 of the American League Championship Series between the Houston Astros and New York Yankees has been postponed due to expected inclement weather in New York on Wednesday night.

First pitch for Game 4 will be 8:08 p.m. ET Thursday. Game 5 has been rescheduled for 7:08 p.m. ET Friday, which originally had been tabbed as a travel day, if necessary.

The Astros have a 2-1 lead in the best-of-seven series. The winner will face the Washington Nationals in the World Series.

The move could affect pitching plans for both teams. The Astros could bring back Zack Greinke for Game 4 on regular rest, and the Yankees -- who were planning a bullpen day for Game 4 -- could instead go back to Masahiro Tanaka on regular rest.

Tanaka blanked the Astros over six innings in Game 1 on Saturday while throwing just 68 pitches to get through the Houston lineup twice.

Games 6 and 7, if necessary, are not affected by Wednesday's postponement and will be held in Houston on Saturday and Sunday.

Wednesday's matchup is the first postseason game to be postponed since Game 4 of the National League Division Series between the Nationals and the Chicago Cubs in 2017, and the first LCS game to be called off since Game 3 of the Baltimore Orioles-Kansas City Royals series in 2014.
