What happened: The four reached base eight times on six hits and two walks in the Wild Card opener against the Cubs. Five batted balls registered over 103 mph, including Manny Machado's knock scoring Tatis to extend the lead.

Why it matters: Winning Game 1 leaves San Diego one win from the Division Series. Concentrating that production across four regulars forces Cubs pitchers to navigate traffic with no soft landing in the middle innings.

What to watch: Watch Game 2 adjustments to the middle of the order and whether San Diego closes the series without going to a decider.
