6. The Alous Form MLB’s First—and Only—All-Brother Outfield
While the above is Felipe Alou, later in his career with the Oakland Athletics, he did something very special a decade earlier, across the Bay.
On September 15, 1963, the San Francisco Giants made history by fielding the first—and still only—all-brother outfield. Felipe, Matty (Mateo), and Jesús Alou patrolled the outfield together, creating an unmatched moment in MLB history. Given the rarity of three brothers reaching the majors at the same time, this family feat feels untouchable. It's one of those legendary baseball quirks etched in history forever.
