Simon Yates won stage 19 of the Giro d’Italia to set up a fascinating final weekend even as Egan Bernal added a few more seconds to his overall lead. Just as he did up the Sega di Ala on Wednesday, Yates rode away from Bernal on the Alpe di Mera at the end of the 166km stage from Abbiategrasso, taking 28 seconds out of the Colombian who remains troubled by a back problem. Bernal took third to push his advantage over second-placed Damiano Caruso up to 2min 29 sec, but all eyes will be on the in-form Yates – 20 seconds further back in third – going into Saturday’s brutal stage to the Alpe Motta before Sunday’s closing time-trial in Milan. “I’m really happy,” Yates said. “The team did a fantastic job today, they really controlled the start and worked a lot and I managed to finish it off. I saw the boys from Ineos were happy just to ride a tempo and I had a feeling they would let me go. I read something from Egan on Twitter about how they would be conservative and try to control rather than go with me, and as soon as I attacked I saw that was correct.” It was on stage 19 of the 2018 Giro that Yates, after 13 days in pink, cracked at the moment Chris Froome sprang to victory, but three years later the 28-year-old is the rider coming into form just as Bernal is put on the defensive. Friday was all about the final 10km climb, with organisers having amended the original route to remove the planned ascent of the Mottarone after the cable car disaster which killed 14 people on the mountain on Sunday. Prize money from the day was donated to the victims’ families. Yates wasted little time in attacking on the climb to the finish, the Team BikeExchange rider going clear with six and a half kilometres to go. Caruso and others tried to follow as Bernal initially offered no reaction, showing maturity as he paced his way up the climb without panic. “I felt really good,” Bernal said. “I did good numbers, a good climb. Of course Yates was the best today and chapeau to him but I’m really happy with my condition. Tomorrow with the altitude I hope to have the same feelings and I just try to manage the gap I have. I have some time to play with and I also want to have good legs for the time-trial. Everything should be OK if I’m feeling good.” But Bernal’s rivals have seen the damage that can be done on a single mountain, and will relish the thought of Saturday’s feast of climbing. The 164km run from Verbania goes over two passes at more than 2,000 metres before the summit finish in Valle Spluga, should be the Colombian’s natural habitat, but after two days of relative struggles this week Yates will get the better night’s sleep. “Today was not the most difficult of stages,” Yates said. “It was a very, very difficult final climb but tomorrow is very different, a very hard stage. We’re back in the high altitude. We’ll see what I can do.”
