What happened: More than 30 family members and friends were on hand to celebrate with Joshua Báez after he became the first player in MLB history to hit three home runs in his debut. The Cardinals shared the scene of the gathering following the game.

Why it matters: The turnout underscores how rare Báez's feat was: no player in MLB history had hit three homers in a debut before him. It also marks a personal milestone for the organization, giving the Cardinals a signature moment to promote around their newest call-up.

What to watch: Attention turns to whether Báez keeps his spot in the lineup and how he performs in his next outings for St. Louis.
