Slovenian ace Primoz Roglic set a serious marker on the Giro d'Italia on Sunday, not only winning the stage nine individual time-trial, but damaging several key title rivals in the process.
European champion and world one-hour record holder Victor Campenaerts was second on the day despite a late mechanical failure, while Dutch rider Bauke Mollema came third to boost his chances of an eventual podium shot.
Roglic, of Team Jumbo-Visma, who also won the opening day's time-trial, finished the 34.8km rain-sodden run to San Marino in 51mins 52sec to win in impressive style.
It was a full 1min 05sec faster than Italy's two-time Giro winner Vincenzo Nibali, and a devastating 3min 11sec faster than Britain's self-declared pre-race favourite Simon Yates, who appeared to struggle on the final climb.
Reigning Vuelta champion Yates led the Giro for over two weeks last year only to suffer a penultimate-stage meltdown, and has vowed to make up for it this year.
The win leaves Roglic, a 29-year-old former ski-jumper, in second place in the overall standings behind overnight leader Valerio Conti of Italy, who had promised to fight and keep hold of the pink jersey.
But above all it puts this season's form rider Roglic, who won the Tour of Romandie, the UAE Tour and the Tirreno Adriatico, firmly in the driving seat for a first ever victory in a three-week tour.
The Slovenian takes a 1min 44sec advantage over Nibali into the mountainous section of the Giro where Nibali's cut-throat tactics saw him claim overall wins in 2013 and 2016.
