Carlos Sainz Jr. will remain with Toro Rosso for the 2017 season, extending his stay with the team for a third campaign.
Sainz Jr. has been backed by Red Bull throughout his single-seater career and won the Formula Renault 3.5 championship in 2014, resulting in a gradutation to Formula 1 with Toro Rosso.
Sainz Jr. finished 15th in last year's championship and amassed 18 points, with a best finish of seventh at the United States Grand Prix.
This season, the 21-year-old Spaniard has finished five of the eight Grands Prix in the points, with a best result of sixth at his home event.
"Very happy to be signed by Toro Rosso for next year," Sainz Jr. posted on social media.
"But it is time to focus [on the] 2016 season as there is still a lot of unfinished business."
Toro Rosso has not yet indicated whether Daniil Kvyat will be retained alongside Sainz Jr.
Kvyat began the season racing for Red Bull but was demoted to Toro Rosso prior to the Spanish Grand Prix, with Max Verstappen moving to the senior squad.
