AUSTIN -- After confirming the extension of Max Verstappen's contract, Red Bull advisor Helmut Marko says it was imperative for the team to tie at least one of its drivers down beyond 2018
Verstappen will be at Red Bull for another two seasons, ending speculation of a switch to the likes of Ferrari or Mercedes in the next few years. Previously, the Dutchman had what was believed to be a 1+1 deal -- a solid contract for 2018 but a less certain option for 2019, which is likely to have included clauses which could have allowed the Dutchman to escape the agreement early in certain situations.
