Marussia has announced Alexander Rossi as its official reserve driver for the rest of the 2014 season.

Rossi left a similar role at Caterham earlier this month following the team's takeover by Swiss and Middle Eastern investors. Having also left the GP2 team, Rossi joined Campos for the German round of the GP2 series and has now been confirmed with another F1 drive as he joins Marussia alongside race drivers Jules Bianchi and Max Chilton.

As part of his new role, Rossi himself confirmed the plan is for him to make some FP1 appearances this season.

"Today is a good day and next step in my Formula 1 career," Rossi said. "Since my initial discussions with the Marussia F1 Team management, I've felt right at home. I'm looking forward to working with the Team in Hungary and building for the rest of the season. The timing of my affiliation with the Team is perfect, especially beginning in Hungary before the summer break.

"My goal is Formula 1, and I'm delighted to be immersed into the Team as Official Reserve Driver, where I have the opportunity to prepare for this next step, with plans to drive in Free Practice 1 this season.

"Marussia is in an exciting place right now and the progress at the team is clear for all to see. I'm thrilled that now I have the chance to be part of that journey, to progress and play a useful role in the development of the Team. I want to thank Marussia F1 Team for the opportunity this season."

Team principal John Booth said he is happy that the team was able to appoint a reserve driver with previous FP1 experience.

"We are very pleased to welcome Alexander to the Marussia F1 Team in the role of Official Reserve Driver," Booth said. "He is a proven talent whom we have observed in GP2 and we have also been impressed by his performances during Friday morning free practice sessions over the past two seasons.

"The US is an exciting market for the sport and Alexander has a great deal of support there, so it is nice to develop new links to that audience. Alexander will be an integral part of the Team, immersing himself in our engineering activity so that he is fully prepared should he ever be required to deputise for one of the race drivers."
