California hosted two MLB contests on June 12, 2026, with the Los Angeles Angels picking up a home win while the San Francisco Giants fell short at Oracle Park.

The Los Angeles Angels defeated the Tampa Bay Rays 4–3 at Angel Stadium in Anaheim. The Angels held on for a one-run victory in what was a closely contested affair, improving their record at home with a gutsy performance against the Rays.

In San Francisco, the Chicago Cubs handed the Giants a 5–1 defeat at Oracle Park. The Cubs offense proved too much for the home side, as Chicago pulled away for a comfortable four-run margin of victory, leaving the Giants with little to celebrate in front of their home crowd.
