Marquez's scheduled start against the Twins on Wednesday was postponed, Mike Berardino of the St. Paul Pioneer Press reports.
Given the game is already set to be played as a doubleheader Thursday, Marquez will likely just see his start pushed back a day, though that hasn't been confirmed yet. The 22-year-old currently owns a 4.88 ERA through four starts (24 innings) with the big club this season.
