There will need to be some patience as Nate gets into this closer role. Control was never his strongest suit, so he may walk or HBP someone in a key situation. But with a one inning role , he can go out confidently and bring his heater for 20 pitches and let it fly, making a curve/slider and change up very effective. His 8 innings vs the Dodgers in the WS shows you may get 2+ innings from him to get the win. No one else in the pen brings that endurance to the table, although Workman did get more than an inning in this week.
I'd give Eovaldi 4 appearances before deciding if he is the answer to closing games strongly. Hope he gets the opportunities to show his stuff before the deadline.
