Kimi Antonelli stormed to his ninth win of the season on Sunday at the United States Grand Prix. The Associated Press and NBC News reported the lights-to-flag drive at the Circuit of the Americas. The Mercedes driver started from pole and pulled away in Austin.

The 20-year-old Italian further tightened his grip on a Formula 1 title chase he could finish at the next race in Mexico City. A victory plus poor results from his closest rivals would have sealed it in Texas. Those rivals scored enough to keep the fight alive for one more weekend.

Antonelli controlled pace and tire wear after an early lead. The pages described a masterful race weekend from qualifying through the flag. Crowds in Austin cheered the young championship leader as he climbed from the car.

Mercedes has built a strong late-season run around Antonelli. Rivals still have a mathematical path if he falters in Mexico. No protest or stewards drama changed the result on the pages.

What we know: Antonelli won from pole in Austin and remains the clear title favorite.
What we don't: Whether he will clinch in Mexico City or need another race.
