What happened: Simpson followed his 44-steal debut season by reaching 40 in 2026. He became the fifth player to clear that mark in each of his first two MLB seasons since the modern stolen-base rule was adopted.

Why it matters: The achievement establishes rare year-to-year consistency on the bases rather than a one-season spike. His career total now stands at no fewer than 84 steals.

What to watch: His remaining regular-season games will determine how far he pushes this year's total beyond 40.
