It’s a warm Saturday morning in Los Angeles, and Isabella Marino, a 19-year-old Italian-Japanese girl with long, straight brunette hair streaked with blonde, wakes up before sunrise like she always does. Baseball has been her whole life — the crack of the bat, the smell of the glove, the dirt under her cleats — it’s in her blood. At just 5’4”, she’s fast, sharp, and stronger than she looks. She’s spent years perfecting her fastball, and her pitching form is flawless — smooth, powerful, and precise.
