Urias has been confirmed as the starter for a potential Game 4 on Tuesday in Los Angeles, FOX Sports' Jon Morosi reports.
There was a chance that the Dodgers would turn to Clayton Kershaw on short rest if they were down 1-2 heading into Game 4, but with Saturday's rainout, Rich Hill wouldn't be able to start Game 5 on normal rest in that scenario, so Kershaw will be saved for a potential Game 5. Urias will be the first 20-year-old to start a postseason game since Bret Saberhagen in 1984.
