Lamont Marcell Jacobs wins the men's 100-meter dash

Lamont Marcell Jacobs won gold in the men's 100-meter dash, becoming the first Italian to ever win the event.

In a wide-open men's final, Jacobs, 26, chased down American Fred Kerley in the final meters to take the gold, setting a new European record with a time of 9.8 seconds. Kerley picked up the silver as Canadian Andre de Grasse took the bronze.

"It's been my dream since I was a child," Jacobs said after his win. "I've won an Olympic gold after Usain Bolt, it's unbelievable. Tonight, staring at the ceiling perhaps I will realize."

Jacobs was born in the United States but moved to Europe with his Italian mother when he was one month old. He had broken 10 seconds in the 100 meters twice earlier this year and won the 60-meter dash at the European Indoor Championships in Poland in March.

The result capped off a big day for Italian athletics. Jacobs' result came 10 minutes after Gianmarco Tamberi shared the gold with Mutaz Essa Bashim of Qatar in the men's high jump. 

"I need a week or so to understand what has happened," Jacobs said. "Seeing Gimbo win the high jump gold fired me up a lot.
