F1: Perez, Leclerc, Sainz Jr and Zhou to take Grid Penalties

Both Ferrari drivers, Sergio Perez and Zhou Guanyu will take grid penalties for the Formula 1 United States Grand Prix Sunday.

The Ferrari drivers are not changing engines until Saturday morning, at which time their grid penalties will become official.

For both Perez and Zhou, it is their fifth internal combustion engine of the season, meaning both Perez and Zhou will drop five places on the grid from their qualifying position on Saturday.

Perez is in a tight battle with Leclerc for 2nd in the point standings, separated by just a single point with 4 races to go.
