Ryan and the Twins won't face the Mariners on Thursday after the Opening Day game for both teams was postponed due to inclement weather.
The contest was rescheduled for Friday, which was an off day in the schedule amid the four-game series. Ryan remains in line to start Friday's game, which will keep the other four members of the rotation on their normal pitching schedules. The 25-year-old right-hander closed the Twins' Grapefruit League slate with six strikeouts in five innings between his two starts.
