From ESPN’s preview:
Everything is pointing toward Nestor Cortes returning from a flexor strain in his left forearm, and because he hasn't pitched since Sept. 18 and isn't built up, the strong likelihood is him slotting into a relief or opener role. New York could be inclined to use him early in the series to see whether his stuff is playing -- and if he can be an effective left-on-left counter to a pocket of the lineup that includes Shohei Ohtani and Freddie Freeman. "It's risky spending a roster spot on a guy you don't know you can rely on," an executive involved in postseason roster construction said. "If he's not good, you can just take him off the roster, but if he costs you a game, you're already regretting the choice."
