The Cubs have the season series against both, so in my mind, we won't hit "things just got interesting" territory unless the gap is cut to one game very soon, like within the next four games, maybe.
Definitely going to make career judgments on a 21-year-old rookie who has actually been pretty decent at the plate, especially when on this very team, we have a guy who was the worst hitter in the league for a year and a half and has turned it around in a big way.
