What happened: Munetaka Murakami put Chicago in front with a postseason home run on Saturday. The blast carried the rookie slugger's late-season power surge into October.

Why it matters: A lead-changing swing matters more in the postseason, where one at-bat can reshape bullpen usage and late-inning leverage. It also reinforces the pressure Murakami carried into October after reaching 35 homers last week.

What to watch: The next question is whether Chicago can turn the lead into a win and how opponents pitch Murakami in later leverage spots.
