What happened: Trei Cruz made his Major League debut, with his father and grandfather in the stands to see it. The night marked the third generation of the Cruz family to reach the big leagues.

Why it matters: Multi-generational lineages are rare in baseball, and a third-generation arrival puts the Cruz family in select company. The debut follows Cruz's call-up that extended the family's three-generation MLB run.

What to watch: Cruz will look to carve out a regular role as he settles into his first stretch of big-league action.
