Honestly its quite sad to see people blasting Del Toro the way many in this forum or on social media are doing.
Yes, he did make mistakes, he should have paced with Carapaz to try to bring back Yates, especially when they were only 25 meters away from him or so but we need to contextualise things, he is a 21 year old that was not even supposed to lead UAE in this race and for the first time was in a position of winning one of the biggest races of the calendar.
If anything, yesterday UAE showed once again how tactically inept they are, first of all they let a rider like Van Aert in the break with such a gap that he can be useful to his leader after Finestre and then they don't tell Del Toro to chase Yates when he wasn't still too far back on the climb, because let's be realistic here, when Yates connected with Van Aert with a 2 minute gap, the Giro was lost but its a UAE defeat above anything, they were the ones that had the goal of winning the Giro not Del Toro himself.
For Del Toro this is actually a very succesful Giro. At 21, he got into a GT podium, won a stage and spent almost two weeks in pink. He showed the world that he is a GT rider and might very well win one in the future.
