What happened: Chourio, 22, sits near the center of Milwaukee's postseason attack as the club begins its October schedule. The Brewers open the NLDS after a first-round bye, putting one of their youngest stars into a prominent early role.

Why it matters: Short postseason series can swing on one bat heating up, and Milwaukee is asking its young core to provide that punch. If Chourio produces early, the Brewers' lineup looks deeper and their path through the National League looks sturdier.

What to watch: The next test is whether that production carries into Milwaukee's opening NLDS game. His first few trips to the plate should be an early read on how opponents plan to attack Milwaukee's young star.
