SPIELBERG, Austria -- Red Bull has exercised its option to retain Carlos Sainz at Toro Rosso in 2018, according to team boss Christian Horner.
Sainz is now in his third season at the junior Red Bull team but has made no secret of his desire to move up to the senior team or go elsewhere in 2018. On Thursday he said it was unlikely he would remain at Toro Rosso, but speaking to Sky Sports on Friday Horner said Red Bull had already exercised its option to keep him at the Italian team.
"He's under contract," Horner said.
