Yes, the Garmin pair are done in the GC race. As a result of this nasty thing in the stage 1 Team Time Trial:
While 2012 Giro champ Hesjedal remains in the race, he is no longer a threat to win this thing. He lacks to skills to make the kind of attack needed to make up 3 minutes without help from someone else that would benefit in a greater way. He might win a stage, maybe even one in the mountains, but he isn't winning the Giro.
As for Martin, the crash is the cap on a disastrous early season where he started his build up later than usual aiming at defending his win at Liege-Bastogne-Liege and then taking a shot at GC in the Giro. Now, he has no real results (a podium at Fleche Wallonne is nice but underwhelming if the only item on the palmares) and has crashed out of Liege-Bastogne-Liege (on the final corner when about to take the lead in the race) and the Giro. With his broken collarbone, he is unlikely for the Tour, making him a rider now targeting the Vuelta in a last chance saloon type of scenario for his season. Just awful for him and his team where he is the captain.
