Yonny Hernandez is to replace the injured Ben Spies for the rest of the 2013 MotoGP season. So far, Spies’ seat has been filled by Ducati tester Michele Pirro, but the stress of racing as well as working through a very busy test schedule has taken its toll on the young Italian.
Furthermore, Pirro racing the three flyaways would have meant that testing would have ceased for the three-week duration, and with work in full swing for the 2014 season, that was not time Ducati had to lose.
