The Red Sox should know soon what the price will be for using an Apple Watch to steal signs from the Yankees last month in Fenway Park.

Asked by The Post on Tuesday night at Citi Field if there was a timetable for a resolution of MLB’s investigation of the Red Sox for stealing Yankee signs with electronic technology, Commissioner Rob Manfred offered a one-word answer.

“Quick,’’ Manfred said on the field before the Yankees’ 2-1 loss to the Rays at Citi Field on Tuesday.

Manfred was with MLB’s Chief Baseball Officer Joe Torre and Senior VP of Baseball Operations Peter Woodfork.

The Yankees accused the Red Sox of stealing signs during a series at Fenway Park last month and the Yankees sent video to MLB. The Red Sox admitted to the wrongdoing.

The Yankees alleged members of the Red Sox’ training staff relayed information from video personnel to players using an Apple Watch.

MLB rules don’t prohibit sign stealing but do prohibit using electronics to do so.
