What happened: MLB.com collected the top moments from the Pete Crow-Armstrong power-speed campaign. The milestone was sealed with a steal of second base.
Why it matters: Only six players had reached both marks before, making it one of baseball's rarest benchmarks. That rarity places the season in the historical record beyond a single year.
By the numbers: 40 home runs, 40 stolen bases; 7th 40-40 season in MLB history.
What to watch: Watch for where the final home run and steal totals settle before season's end.
