Duffey threw five scoreless innings with two strikeouts and one walk in Monday's win over Toronto. He has a 3.86 ERA with a 6:1 K:BB in 11.2 innings this spring.
Duffey delivered a strong outing against a Blue Jays lineup that featured most of its starters. He remains in the fifth starter competition that will likely be decided next week, once Jose Berrios returns from the WBC.
