Relentless storms in the New York area forced a postponement of Wednesday nights game at Yankee Stadium. The forecast projected no halt to the rain throughout the night.
The Yankees made the announcement just prior to 2:30 p.m. Eastern time, or roughly 4 1/2 hours before the scheduled start at 7:05 p.m. Eastern time (4:05 p.m., Pacific time).
No makeup date was announced.
The Mariners plan to shift lefty Roenis Elias to Thursdays series finale, but the Yankees plan to skip David Phelps and use Hiroki Kuroda, who had been scheduled to pitch Thursday.
Phelps is normally a reliever but had been slotted for a spot start following a suspension levied to Michael Pineda, an ex-Mariner, for applying pine-tar to the ball in his last start.
With Elias shifting to Thursday, Felix Hernandez will now start the series opener Friday in Houston. That makes it likely Hisashi Iwakuma will be activated from the disabled list in time to start Saturday against the Astros.
Iwakuma worked four innings last Sunday in a rehab start for Triple-A Tacoma at Las Vegas (Mets) that marked his first game action since being diagnosed in February with a strained ligament in his middle finger.
