What happened: Nolan Arenado hit his second home run of the night, doubling up in a game broadcast on FOX. It's his latest power display in a season that has already produced notable career milestones.

Why it matters: The two-homer night builds on a stretch that saw Arenado become the sixth player in MLB history to reach 2,000 hits, 350 home runs and 10 Gold Gloves. Continued power production keeps his name in the conversation as evaluators weigh his Hall of Fame case.

What to watch: Watch whether Arenado adds a third homer before the game closes out.
