Alexander was left off the NLCS roster after only one appearance in the NLDS, tossing a perfect eighth inning in a Game 3 loss in Atlanta. The lefty appeared in 25 games, allowing 11 runs (10 earned) in 18 innings over the final two months of the season for the Dodgers.
The 22-year-old Ferguson was outstanding for the Dodgers as a reliever in 2018, going 7-1 with a 2.35 ERA in 38 1⁄3 innings over 26 appearances.
Ferguson appeared in four games in the NLCS, retiring four of the five batters he faced.

Boston made a change of their own, adding lefty Drew Pomeranz in place of Brandon Workman. Pomeranz makes it as another lefty option, but hasn’t pitched since September 30.
