And he followed that up with a second goal, tapping in from close range after a defensive mix-up.
Usain Bolt taps in a second and follows it up with a #Fortnite celebration!

Bolt expressed his delight at his headline-grabbing debut, saying: "My first start and scoring two goals, it's a good feeling.
"I'm happy I could come here and show the world I'm improving. I'm keen to be a Mariner, to play my best and get into the team."
Bolt has taken steps into professional football after hanging up his running shoes, having won eight Olympic gold medals during his sprinting career.
An outspoken Manchester United fan, the 32-year-old has previously trained with Borussia Dortmund, and played in Soccer Aid at Old Trafford.
He hopes to win a permanent contract with the Mariners, and his two goals on Friday will have done nothing to harm his chances.
"I think [Bolt] can make it. I don't really know the level of the Australian league and I don't know the teams there," Gotze said.
"He is a sportsman and he has a lot of abilities that are important to be successful in football, too."
