Treinen has not been given the closer role, but he is the leading candidate for saves, reports Bill Plunkett of The Orange County Register.
Dodgers manager Dave Roberts stated, "Right now where we're at, we don't have a dedicated closer." While this seems a negative, Roberts also mentioned that the "easy answer" would be to turn to Treinen as the closer. It's possible the veteran reliever will be needed to put out fires earlier in games occasionally.
